What you want is something like this. I know/knew a guy who lived out of one of these and used it like a mini-rv.

He gutted the back and installed a bunk bed, shower, kitchen with fridge/freezer and some general storage.

If you have somewhere you can park it and can make use of some of the surrounding land you can do a few neat things.

1: use a compost style toilet. Build a compost bin and all your organic waste (this includes human waste ie: poop) goes into the compost bin.

This only leaves plastic and metal trash that can be recycled. So you won't need to pay for trash service or deal with sewage.

If you don't have room to build a shower in your van/truck you can build a small outdoor shower. Anything from a $10 solar shower bag from wal-mart to a 5 gallon bucket of water heated with a portable plugin water heater. You can buy those at any farm & tractor supply type stores.

They heat up fast too, 5-10 minutes. You can also use this method to heat water for doing your dishes too.

For that you'll want 3 plastic tubs from wal-mart ($1-2 apiece) Use one for hot soapy water and 2 others with clean water for rinsing. Wash, prerinse, rinse.

For food, your cheapest bet is dry/canned goods. Or you can get a small fridge or freezer and run it off a battery and charge the battery up once or twice per day.

For cooking you can get gas powered stuff and cook outside or electric portable stuff (toaster oven, microwave, hot plate) and just turn your vehicle on when cooking.




u/OrangeCurtain · 9 pointsr/Homebrewing

Should be possible if you can DIY the electrics or know someone who can...

u/sillycyco · 8 pointsr/firewater

220 definitely. 5500w element like this one.

Controller like this or similar DIY. I would add a volt/amp meter to get some feedback, like this one. If you have money to spare and want to go top of the line, a controller based on this unit is the most versatile. You also need an SSR and a temp probe, as well as a box, wiring, etc.

As for connecting it up, most triclamp to element kits I've seen are 2". So perhaps an integrated element/1.5" TC like this would be good. Otherwise, a simple adapter like this would work if you have the other parts.

u/xbox666 · 6 pointsr/CannabisExtracts

you need a digital temp controller ( here ), a 1000watt horse trough heater ( here ) and a submersible pump ( here ).

u/AllMenMustBlergh · 6 pointsr/whatisthisthing

But you can still buy them.
Even for the car!

  • Aeropress
  • Porlex grinder (fits inside aeropress handle)
  • A handful of paper filters and a reusable SS filter
  • Small scale for measuring beans (water I do by volume in the AP)
  • Third Wave Water (Only if I'll be staying in one place for more than ~4 days because you need to buy a jug of distilled water)
  • Immersion water heater (if I suspect I may not have an electric kettle)
  • Good beans
u/reimannk · 6 pointsr/BuyItForLife

I've installed two of the Takagi T-KJr. They're built like tanks, have been around forever, and are pretty efficient. They're also pretty inexpensive ($500-$600). I'm up in Wisconsin, so if this heater can keep up with our crazy delta Ts in single bath houses, I know it'll be able to keep up with your needs just fine. There are some larger heaters from other companies like Triangle Tube and Rinnai that are good, but they are much more expensive or oversized for what you need.

u/Codebender · 6 pointsr/Coffee

Have you tried pre-heating your french press with some additional boiling water so it doesn't cool so fast? You could also wrap it in a towel, insulating foam, etc..

I haven't looked, but I assume you can find vacuum-insulated french presses.

Another possibility is one of those submersible water heaters, but it might be tricky to hold a good temperature.

u/drinkduckshit · 5 pointsr/tea

Sounds like you could use a [collapsable kettle] (https://www.amazon.com/Useful-UH-TP147-Electric-Collapsible-Travel/dp/B00ZJHXNIU).

Or even better, you could use an [immersion heater] (https://www.amazon.com/Lewis-N-Clark-Portable-Immersion/dp/B001U0PB1C/ref=pd_lpo_60_bs_t_2?_encoding=UTF8&refRID=HQQTG0FG7821QSZJFXMB).

Immersion heaters work with any size container you want.

You can ask the cafe attendant for hot water, or just bring something like this (I think mine was under $10 at the local hardware store)

u/alf3311 · 4 pointsr/Homebrewing

Random thoughts:

  • if your tap water is colder than room temp, fill the kettle the night before so it has time to warm up a bit
  • put a lid on the kettle (only for heating up: you want the lid off for your boil)
  • upgrade your propane burner. E.g. the new Blichmann burners put out 140k BTU/hr and some of them top out at a crazy 220k BTU/hr.
  • make sure you have a wind-screen around your propane burner. Sometimes cheap or DIY stands omit this and it causes the burner to be a lot less efficient
  • make sure you have adjusted the air/propane mixture. you don't want any orange flames.
  • some sort of submersible electrical heater
  • heat some of the water up in a smaller pot on your kitchen stove, then combine
  • find something else to do while the water is heating up. prep ingredients, sanitize your fermenter, drink a beer, etc.
u/thingpaint · 4 pointsr/analog

I built a hot water bath using a temperature controller and heating element I got from Amazon. Whole thing cost me $70. Mounted the heating element in a plastic tub, wired up the temp controller, added a small aquarium pump to keep everything mixed well.

Element: https://www.amazon.ca/Camco-02203-2000W-Heater-Element/dp/B0006JLVBW/ref=sr_1_3?ie=UTF8&qid=1487969670&sr=8-3&keywords=heating+element

Don't buy the A.O. Smith rigid rod. There is nothing special about theirs. Get a flexible unit. Available in aluminum/zinc, and magnesium.

u/jam905 · 4 pointsr/Plumbing

Full disclosure - my day-job is a research microbiologist and my lab works on anaerobic bacteria.

Your water heater has something called a sacrificial anode rod in it that is electrically contiguous with the steel tank. This anode is made from a less noble metal than iron; as a consequence, the anode is more reactive and sacrifices itself to oxidation preventing the steel tank from rusting away (rust is iron oxides).

Anodes are typically made from magnesium with a steel core. Here's where anaerobic bacteria come into the picture. They are present in municipal water supplies, and some of them thrive in an environment that is around 120-130^o F. Many of the enzymes they need for their growth are dependent on divalent cations - especially magnesium, the material the anode is made of. The anaerobic bacteria enter your tank with the municipal water supply and establish themselves in this niche. As indicated by u/wtfgolf4fun, the product of anaerobic respiration is hydrogen sulfide, which smells like rotten eggs.

There are two things you need to achieve:

  • Get rid of the bacteria (and therefore the smell)
  • Prevent the smell (and bacterial growth) from happening again

    Let's start with getting rid of the bacteria. Cut the power to the water heater. Remove the existing anode rod. Drain the tank. Add 3-4 gallons of drug-store hydrogen peroxide (3%) and let it sit for 1-2 hours. Then drain the hydrogen peroxide as well.

    Next, how to prevent the smell from re-occuring. Aluminum and Zinc are also less noble than steel, and are not used effectively as divalent cations to support the growth of anaerobic bacteria. You can replace the magnesium anode with one made from aluminum or zinc. There are also permanent electrically powered anode rods; these run around $100, and will last the lifetime of your tank (~20 years).

    In addition to changing the anode with an aluminum/zinc/powered anode, you should also raise the temperature for the upper and lower thermostats to 140^o F. This is high enough to kill >99.9% of the anaerobes typically present in municipal water supplies. If you do this, be aware that the higher temperature can scald. To prevent that from happening, you should install a water heater tank booster - so that the water temperature at hot water faucets remains 120^o F.

    When you're all done, make sure the water heater is filled with water (i.e. cold water comes out of all hot water faucets) before restoring electric power to the heater.
u/baggar11 · 4 pointsr/HomeImprovement

I've had a tankless for about 8 years now. I love it. Endless consistent hot water is awesome. Even though we use a lot of water in our household, our bill has gone down too. Probably mostly due to the really old inefficient water heater before.

If you really want upwards of 9 gpm, then yeah, 2 tankless water heats in series will probably do the trick. You may look into adding on a real small water heater, like a 6 gallon unit to handle the recirculation and prevent the cold water sandwich effect. Most recirculation pumps aren't recommended for tankless.

u/Belial88 · 4 pointsr/WTF

You're wrong. The average cost of electricity is ~$0.11/kWh. 1000w is enough to boil three gallons of water very quickly, just google 'water boilers 1000w: http://www.amazon.com/MARSHALLTOWN-Premier-742G-Bucket-Heater/dp/B000BDB4UG/ref=sr_1_1?s=hi&ie=UTF8&qid=1356817956&sr=1-1&keywords=Bucket+Water+Heater . The true cost of the extra cup of coffee is a tiny speck of that, as we are calculating just the increased energy usage vs normal coffee heating, so we're talking maybe a penny's cost for each pot of coffee.

A small coffee at McDonalds costs is $0.99 before tax.

One extra cup would greatly offset the cost of heating a pot. That's a 900% return on that investment. That's insanely huge, and now you see why McDonald's did it.

On top of that McDonalds sells ~1 billion cups of coffee a year (http://scheingrosslaw.com/mcdonalds-coffee-lawsuit/). A pot of coffee makes ~12 cups of cofee. That's a 8% increase in coffee sales with a 0% increase in food cost. That's 80 million cups of coffee that cost McDonald's less than a penny each to produce.

You can see very easily now, why McDonald's would say 'fuck you lady'

u/machinehead933 · 4 pointsr/Homebrewing

Typically the electric stoves dont have enough power to do a full boil. You can supplement the power of your stove with an additional heating element like a heat stick(plenty of DIY instructions floating around), or one of these.

u/Navec · 3 pointsr/Homebrewing

I am unaware of anyone who sells kettles with threaded connections big enough for heat elements.

I would recommend getting kettle with a 1.5 TC port or using a weld-less 1.5 TC bulkhead and pairing it with a 1.5 TC heating element with the locking plug like this one. It is so nice to be able to "unplug" your kettle when you clean it.

u/lostron808 · 3 pointsr/povertyfinance

FWIW:
https://www.amazon.com/dp/B077K428LC/ref=dp_cerb_1

Garden hose+ propane tank + portable water heater = bliss.

I’ve used these style heaters off grid for years, they work very well!

u/jaimefeu · 3 pointsr/personalfinance

That's what they're called. Water heater blanket and water heater insulation pad. They sell them on amazon and at home depot. You just need to measure your heater to make sure you get the right size. Most of the blankets are 'universal' cut to fit, so it's more of a question of how thick to get it.

I was going to get this one, but eventually decided that since my water heater was in the same room as my gas boiler - it wasn't really necessary.

u/Acidsparx · 3 pointsr/solotravel

I did a 100 day backpacking trip around the world with a North Face Backtrack 50. It was small enough to be a carry on. Some advice others have mentioned here, first aid kit is very important, along with copies of your passport and some passport photos just in case. You should also have photocopies of your credit cards and their 1-800 number if you're bring them along. A lock to keep your belongings safe. Travelers duct tape is also useful. They're small and doesn't take up space but very handy to have. If you'll be doing laundry yourself without a machine, a sink stopper and cloths line are useful too. Eating utensils are also useful like this immersion heater, or fold up cups etc.

Wardrobe is fine, though it's better to use synthetic fabrics for t-shirts and such since it dries faster and doesn't wrinkle like cotton does when you shove it into a bag. Also to not stand out as much as a tourist, all your cloths should also match. Greys and browns work well with everything should you decide to wear the same cloths a few days in a row. If you're paranoid about getting robbed, a money belt is also good. If you get past the dorkyness of it's wonderful. I had most my stuff in it while keeping some money in my pockets. You don't want to be whipping the belt out for every purchase. That's all I can think of at the moment. If i come up with more I'll edit this comment.

u/McFeely_Smackup · 3 pointsr/HomeImprovement

Looks like the heater shoudl be about $900

since it's replacing an existing tankless heater, I'd think MOST of the work for installation is already done.

Last time I had a problem with the price of a job, I asked the contractor to estimate the time it would take, subtracted materials, and then asked what justified $500 per hour for labor.

Either way, $1200 - $1800 for installation sounds high, by about $1000. I'd get a few more quotes.

u/Frackenbrau · 3 pointsr/Homebrewing

if you haven't already bought the kettle, I'd highly recommend something with tri-clamp adapters like Bru-Gear. Its a little more money up front to buy all the TC fittings but you can completely disconnect everything with minimal effort, including your element, for cleaning. then you can go with the 5500w stainless steel element.

u/Daph · 3 pointsr/Homebrewing

I'll start with the electrical device, it's a heat stick. You can build one yourself, but I opted to buy one from Amazon. You stick it in the wort and plug it in and it adds some direct heat to help boil faster. It makes a night and day difference in the speed it takes to get to boil.

I made the insulating jackets myself out of some Reflectix and Foil Tape. I can't really tell you how well it's doing with 10.5gal pot since I wrapped it right away so I don't have any good before/after there, but with my 5 gallon pot it allowed me to get to boil a couple minutes faster and also allowed the pot to hold the boil on its own, meaning I could take the heatstick out once it got boiling.

Another thing you can't see in the picture, is the 8" element is a canning element, which is a bit higher wattage than my regular 8" element so it burns a bit hotter, which helps with boiling.

u/EchoesOfSanity · 3 pointsr/Homebrewing

Have any of you used something like THIS to help your stove keep up, or have any similar suggestions? I did my first boil last weekend and the coils on my stove actually burned through their coating. I plan on using propane outdoors in the spring after this upcoming Minnesota winter.

I also drained a few gallons from the water heater and put in about a gallon of bleach right before I placed the new powered anode

u/xSW3ATYx · 2 pointsr/cocktails

I imagine something like this would do the trick. Off flavors from the aluminum should be minimal. It certainly isn't as cool as the iron rod though.

u/EternalStudent · 2 pointsr/Homebrewing

Hey dude:

I brewed a lot in a small bachelor's barracks in Korea with a shitty coil stove top.

  1. You don't want a 5 gallon pot; boil overs for days. I had a 7.5 gallon pot and for a full-volume boil, that was a bit too small. Even for a stove top, you'll really want a 10 gallon pot with a ball valve (i had a siphon. Siphons suck. A lot of people will tell you (myself included) that one of the biggest steps you can take for your beer to taste better. If I could do my first step all over again, i'd have gone with one of these: https://www.amazon.com/Bayou-Classic-gallon-Kettle-Stainless/dp/B00OBMB7CI?th=1 (or a Spike).

  2. Get the bigger pot even with a smaller stove. You can get a number of 110v water heaters on the relative cheap that'll bring it up to a boil super quick. I had (I think) this one, and it worked just fine to bring 6 or 7 gallons up to a boil in combination with my stove. https://www.amazon.com/Precision-Premier-Line-742G-Submersible/dp/B000BDB4UG/ref=sr_1_3?ie=UTF8&qid=1509719891&sr=8-3&keywords=bucket+heater

  3. You'll want to cool that down. An icewater bath tub will take its good god damn time getting there; you might want to look at an immersion chiller (NY Brew Supply sold me a 50 foot one on the dirt cheap back then).

    For the record, I did all of this (and got an insulated bag for temperature control) before I did my first batch; if you make it more painful on yourself and get an inferior product, then you'll probably not want to do it again.
u/JoNahNuhNah · 2 pointsr/Homebrewing

Thank you! Just purchased this water heater, by browsing your list. It's exactly what I need to get my water up to temp on my dinky stove!

u/evlpengwyn · 2 pointsr/Homebrewing

I used this one when I was stuck brewing on the stove in my last apartment:
http://www.amazon.com/Allied-Precision-Premier-742G-Bucket/dp/B000BDB4UG

Gave me no issues at all, though I've since moved into a house where I can brew outside with propane.

u/TheRealOzz · 2 pointsr/Homebrewing

The heat sticks will help get you to strike temp, but not really to boil. If you do decide on one, I would recommend changing the male plug end to one of these:


https://www.amazon.ca/gp/product/B00I97LLEA/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1


Or just make sure you plug it into a GFCI circuit.


Alternatively, you can punch a hole near the bottom of the grainfather, below the basket line and add one of these:

http://www.amazon.com/Camco-02853-Screw-Foldback-Element/dp/B000KKVZUO?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

That will give you far better results than the bucket heater...but you're then drilling a hole in your brand new toy.

u/AbsolutelyPink · 2 pointsr/HomeImprovement

Agreed. Those propane units are awesome.

You could also use a camp shower bag. Hang outside during the day to warm. Now, those aren't going to be very long showers, but enough to get a person clean. I suspect you'd need a bag per person.

Another option is this added to this. Again, it's going to be a short shower, but it will work.

u/skeezyrattytroll · 2 pointsr/Cooking

stinger although what we used was home made.

u/socsa · 2 pointsr/Homebrewing

Technically, the primary reason to fully boil the wort is to reduce the volume and concentrate it. DMS decomposition occurs starting at around 120F IIRC, and evaporates down to 100F or so. The Oxide (DMSO) is much less volatile, and does not evaporate until about 180F, but is generally produced in much lower quantities (especially if you are doing extract, since there really should be no reason for excess oxygen to enter the wort). Hop acids and whatnot dissolve just fine at non-boiling temperatures.

Honestly, it's far from ideal if you cannot reach a full boil, but it also isn't the end of the world. It's more important to not cover the wort if you can avoid it, and keep it as hot as possible. You'll end up with beer on the other side, and it will probably taste fine, if not a bit weaker than expected, though once again, since it is an extract brew you can just use less water to top it off (or throw in some extra extract to compensate). If you want to stay electric and indoors, you can try something like this to help you get a better stove boil.

u/ace915 · 2 pointsr/Homebrewing

I bought a bucket heater, and it is great! Plug it in, go do some stuff and come back later to strike temp. Or set up with a temp controller/timer, etc.

u/scottfl · 2 pointsr/IAmA

This is difficult to answer because everyone tours differently. It's entirely possible to travel anywhere in the US, Canada or Mexico and not spend a single penny on lodging. You have to be very flexible with how far you are willing to travel in one day and where you are comfortable sleeping though. Sometimes I can find a free place to camp within a couple miles of looking. Other times I've had to ride 20 miles.

If you like staying in motels plan on that costing about $30-$60 per night on average anywhere in the US/Canada. In Mexico they run $10-$20 on average.

Campgrounds in Canada are expensive--usually $15-$20 a night on average. Along the West coast in the US they have hike/bike CG's that charge about $5. There are no campgrounds in Mexico except a couple on Baja. It's not hard to find free places to camp here but I prefer motels.

Food costs can also change a lot depending on how you tour. If you bring your own stove, cooking stuff and food you'll spend a lot less. If you stop and eat meals in restaurants that'll add up. You will eat a lot of junk food. On any given day I burn 5000-6000 calories so I have to keep eating. I probably spend $10-$15 on just between meal food per day. In Mexico all food is cheaper, especially at roadside stands. You have to buy bottled water down here so that adds some extra cost. I usually cook my own food even if I'm staying in motels. Get an immersion heater!

Bicycle costs can be high especially if you go with expensive components. I've replaced 2 chain rings, a chain, a rear cassette and paid $300. I could have bought cheaper ones but I don't want parts breaking in the middle of no where. If you can tune your own bike (or car) you'll save money too.

u/awkwardsoul · 2 pointsr/tea

There are these USB/plugin hot plate cup warmers out there, but i haven't tried them myself. https://www.amazon.com/Mr-Coffee-Warmer-Office-MWBLK/dp/B000CO89T8/

There are also immersion heaters designed to heat contents of a cup. I also haven't tried it myself, but always tempted to buy https://www.amazon.com/Portable-Water-Heater-Aluminum-GCG/dp/B00PFZFK78/

I'd use a vacuum stainless steel flask. That would be less work and less energy used as you'd only have to fill it once.

u/compulsivehobbyist · 2 pointsr/HomeImprovement

Look into replacing the anode rod in your hot water tank with a powered titanium rod. We just moved into a house we well water that smelled strongly I sulfur. I shocked the hot water tank with bleach (and then flushed thoroughly afterward) but also switched out the anode rod. I guess the corroding metal of the usual magnesium/aluminum produces a lot of hydrogen which leads to the production of hydrogen sulfide which is the rotten egg smell

Corro-Protec CP-R Titanium Powered Anode Rod for Water Heater (40-80 gal tank) https://www.amazon.com/dp/B01H459TAK/ref=cm_sw_r_cp_apa_vHpVBbGD1GMJ1

u/skunk_funk · 2 pointsr/Homebrewing

My setup is indeed a cooler box with a ball valve poking out it, using the steel braid from the outside of a hose to lauter (and a few other things like a 1/2" nipple through where the drain was and a hose to drain it) but you can just use a kettle with a grain bag in it. If you go the cooler way, make sure everything is stainless or brass cause it'll taste like shit if your stuff corrodes in the mash.

Something like this could be used to supplement your stovetop. I actually do the boil in 2 separate 5 gallon kettles on the stove top myself, so don't need one. If you want to do it on a stove top in one big kettle you may need supplemental heat, 1500W should be plenty. Most people buy an outdoor propane burner for it.

u/totally_rocks · 2 pointsr/HomeImprovement

Let's do some math, and see what your water usage is costing you now. I'm going to assume you're not doing laundry with hot water, if you are, stop. Just turn off the hot water to the washer, you don't need it. I'm also going to assume 10 minute showers each, and a load of dishes every two days. And I'm going to assume you have fairly typical equipment, 2.5gpm shower heads and a standard water heater.

An electric water heater with a 3000W element can typically heat 13.1 gallons of water/hour from 50degF to 140degF. [Water heater recovery rate = watts / (2.42 delta t).] And a fairly typical water heater losses about 70watts to standby losses.

So, two 10 minute showers at 2.5 gallons per minute is 20m
2.5gpm = 50 gallons for shower. And lets say another 5 gallons per day for the dishwasher. That's 55 gallons per day.

55gallons / 13.1gallons/hour = 4.20 hours per day that your water heater needs to run to heat that amount of water back up. 4.20 hours $0.0962/kWh 3kW = $1.21/day to heat that water. Add in 0.070kW 24 hours $0.0962 = $0.16 dollars per day in standby losses, for a total of $1.37 per day to run your hot water heater. $1.37 365 / 12 = $41.72/month for hot water.

Now, lets see what can be done with that for much cheaper than the other options you listed.

I have a low flow shower head that I would easily recommend, it's 1.25gpm. You can find them on amazon.com for $8.00

That alone will reduce your usage from 55 gallons per day to 30 gallons. So those calculations then become 30gallons / 13.1 gallons per hour
3kw $0.0962 per kWh = $0.66/day or $24.99 per month.

A drain water heat recovery unit
gets more efficient the lower the flow rate is. Lets say that at 1.25gpm a 42inch model is 50% efficient, it's likely better than that, but we'll call that good enough. But lets also consider the temperature losses from the water heater to the drain about 20 degrees F. 140 deg F - 50 deg F = 90 Deg F delta T. 90 deg F - 20 deg F (losses) = 70 deg F. 0.5 70 deg F = 35 deg F 90 deg F - 35 deg F = 55 deg F. So your new delta T with a smallish drain water heat recovery unit is now 55 deg F when water is flowing in both directions through it.

3000/(2.42
55 deg F) = 22.5 gallons per hour that your water heater can now make when showering.

Now your usages will cost: 30 gallons / 22.5 gallons per hour 3kW $0.0962 per KWh = $0.385 per day or $11.7 per month. With a total of $28.3 per month.

Now lets talk about those standby losses. You can get an R10 water heater blanket that will most likely double the insulation on your water heater. Add R10 worth or rigid foam insulation under the water heater to complete the envelope, and heat traps to slow the flow of heat up the pipes, and that should reduce the standby losses by half. So, $0.16 / 2 = $0.08 /day.

With those things, that would effect any water heater and can stay with the house and not with the water heater, you're now looking at $22.53 per month, a savings of $19.2 per month.

Then, you sit back and wait for mini split heat pump water heaters to make it big in North America and then you upgrade. Or just use solar panels to supply that much smaller amount of power you now need to heat water with a traditional electric water heater.

I'd also recommend a powered anode because changing the anode is a pain in the ass, and insulating your water pipes as much as you can.


*I did the calculations for the drain water heat recovery unit while I waited for the American homedepot site to load so I could get a relevant link only to find they don't list the same 42 inch version I'm putting in my place. I'll let you figure out which one to get and where

**If your showers are longer or shower, hotter or colder, than I calculated for, that will obviously impact the number quite a lot.

I brew ten gallons on the stove top with a 15 gallon blichmann boil kettle and a heat stick.

The manufacturer says it wasn't designed to be food-grade safe regarding the welds for the casing, but hey, at the amount I drink, brewing at least three times a month on a 10-gallon scale, I'm pretty sure cancer from the heat stick is the least of my concerns.

u/blpsoup · 2 pointsr/Homebrewing

I use this: https://www.amazon.com/dp/B000BDB4UG/ref=cm_sw_r_awd_LKjTub0HX6E86

I just plug it in and set it into the center of the wort. This stick elevates the temperature in my kettle to a rolling boil without fuss.

bucket heater

u/chuck1011212 · 2 pointsr/TinyHouses

I have the ecosmart11 tankless hot water heater. I like it for space efficiency and simple installation, but it requires a 60 amp breaker dedicated to it.
https://www.amazon.com/gp/product/B001LZRF9M/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

You might be able to get by with an Ecosmart8, but it still requires to be wired directly to a 40 amp breaker. This is lots of amps to dedicate to hot water, especially if you are working from a 50 amp service at an RV park or wherever you have your trailer parked. Zero overhead even with the 8 for things like A/C and cooking. You could make it work if you were very careful about when you were using hot water, but I would skip it and go with a propane unit like jamilbk linked.

I am thinking about going with a standard issue front load washer and dryer, but just stacking them to save space. The top load washer combo with the dryer on top commonly used in condos and apartments are small in stature, but take up almost the same space as a real front load washer and dryer that are stacked. These front load washer/dryer combo units are really costly and seem to have more complaints about performance and repairs.

Regardless, if you are living in a tiny house on wheels, dedicating space to a washer and dryer might not be on the priority list.

u/Fuckingnarwha · 2 pointsr/GoRVing

For those who said it’s impossible, the flagstaff 176LTD. Two beds, dinette area, space to put portapotty (next to the cabinet by the trailer “queen” size). Out side they have hook ups to set up the grill. Instead you can hook up a portable tankless water heater/ shower and have an outside hot water shower. All this with a GVW UNDER 1500lbs. That should give you wiggle room to actually put stuff in it and not blow up your transmission. It also has a small “refrigerator” and is well under $10k even if you bought the water heater and porta-potty. Keep in mind, it’s an 8 foot box, so it’ll be small, but it has all your must haves.

u/damb_b · 2 pointsr/Homebrewing

This is probably the best tool I own when it comes to BIAB on an electric stove. With it, I can boil 6.5 gallons of wort in about 15-20 minutes (in conjunction with the stovetop on high).

u/arizona-lad · 1 pointr/HomeImprovement

Here is how you can get a happy compromise. Purchase a normal water heater with a replaceable anode. Where
I live, that would be anything but the cheapest, 6 year warranty models.

Then, before you install it, remove the anode and coat the threads with a never-seize product. Years down the road, this will allow easy removal.

Then buy a second anode. All the Big Box stores sell them. Replace it every five years or so. This will keep rusting to a minimum, and lengthen the tanks lifespan considerably.

Then buy a water heater blanket. This is a product that offers you an additional R-10 in increased insulation:

This route will save you several hundreds in cost versus the Marathon system.

I have a Bosch 2.5 gallon electric water heater which works great.

I have a pretty robust electric setup (400 Ah battery capacity, 400 w solar, 3000 w inverter), but I could probably get away with less.

You're also going to need to be able to do the rough in plumbing, which is fairly straightforward but might be challenging if you're not particularly handy.

I'm looking into going electric for my 2 gallon all grain batches. I don't want to drop a few hundred dollars on a new kettle and induction cooktop, as of right now. Also living in an apartment, so I can't go 240v.

Would a water heater element this size get a good boil on 3 gallons of wort?

Using a 5 gallon boil kettle, FYI. Thank you!

u/goongirlgetit · 1 pointr/DIY

I'm just a regular joe coming from /r/all, but I had the thought of using heat. I'm thinking either a torch set to a low flame, or a handheld electric heater like this.

Obviously potentially dangerous and destructive, but I think if you keep your eye on it and be careful, you could achieve a nice melted layer on the inside.

Edit: Thought of something else. You might be able to buff the inside smooth, like with a small felt buffing tip or a smooth metal piece of some sort in a drill. This might technically be called burnishing.

u/TheDarkHorse83 · 1 pointr/Homebrewing

You can get a water heater style heating element and install that into your kettle. If you have 120v (standard for US) then you can get this one, if, however, you have 240v (also US, but for electric driers, ovens, and furnaces) then you can get something with a little more power.

For the driftwood you can always get a 55 gallon drum and a bucket heater and insulate the drum to actually get it to near boiling temperatures or add a second bucket heater to get it boiling. I used the foil covered bubble wrap stuff when I did mine. Plus had it sitting on a 2" piece of styrofoam to keep it off the cold ground. With one heater I got it to about 180℉. Walked into a muggy jungle garage when I did that.

Perhaps using something like this.

This being an electric element, you SHOULD NOT get in the tub while this is immersed and plugged in.

u/prototagonist · 1 pointr/HomeImprovement

This isn't true.

  1. Tankless water heaters are [24% - 34% more efficient] (https://energy.gov/energysaver/tankless-or-demand-type-water-heaters) than tanked water heaters according to the department of energy.

  2. The amount of power required to heat your water can be extensive, however based on OP's location (Hawaii) he only needs a 60 amp double pole breaker to heat his water - which may not even be much of an upgrade depending on what electrical service is running to his current water heater.

u/rr_power_granger · 1 pointr/roasting

Hi all, my goal is to construct a fluid bed roaster capable of roasting a half-pound of coffee per go.

For the motor, I'm looking at this electric leaf blower, and for the heating element, I'm looking to dissect this heat gun.

I'll use a pyrex baking tube, and a cocktail shaker to cap it off at the base. And then some machining magic to couple it to the mounting pipe.

Does it seem like this will get hot enough to roast a 1/2 pound?

I'm trying to upgrade from my current popper setup which can roast a max of 60 grams at a time (and that's with me constantly agitating with a shish kabob stick).

Edit: One possible improvement could be increasing the wattage of the heater to 2000W. Does anyone have a recommendation for a really cheap blower (or just the element itself)? Or would this water heater element work?

If I reclaim the air from the exhaust back into the pump, would this allow a 1500W heater to work?

u/stonecoldsteveurkell · 1 pointr/Homebrewing

Unfortunately, we bought the control panel used so we don't know how it's wired. These are the heating elements we're using. We brewed a batch a few weeks ago with a straight heating element that's 3500W and it didn't trip.

I guess he was saving water, and instead of using hot water, he used this to keep the water hot, or heat it up. he passed away in the tub with this thing still in there, it might not have been an active boil, i'm pretty sure it was just like a huge slow cooker..yeah, near boil, until it dried up. i'm sure that it was a few days before they found him.

    The last one is going to be a pricey project, but my stove can barely boil 3 gallons. The only way I get a good boil going is to turn up the heat, and use a heatstick in the kettle at the same time.

9a, northeast florida. Doesn't get too cold here, but cold enough I lost a fish in October without a heater. The temperature controller is an STC1000, commonly used for homebrewing but it works great for the tank as well, the temperature probe it comes with is water proof, and its cheap. The heater is a 5 gallon bucket heater, designed to get 5 gallons quite hot, but does a good job of keeping 250 gallons at 65. http://www.amazon.com/gp/product/B000BDB4UG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

Right now it's in the 40s outside overnight, but usually in the 50-60 range, with really cold snaps to the 20s. I have my system in a plastic tarp greenhouse. The tarp just keeps the wind out because its too thin to actually hold any heat. I'm upgrading to a "real" greenhouse type of 6 mil sheeting that should help hold in heat and maybe reduce the time the heater has to stay operational.

I also have a mini rocket mass heater I built on the side of the tank as an experiment. The exhaust runs through about 60lbs of sand stacked against the side of my wood and pond liner tank before exiting out the top of the greenhouse. Plan was to run that for a few hours before really cold nights, heat up the sand and help keep the side of the tank warm. In reality I dont think the heat is transferring through the wooden walls the tank much if at all. And any ambient heating the sand and heater are doing is being lost through the thin plastic sheeting. I'm interested in seeing how that changes with the thicker plastic too. I only just got the mass heater working though, so it doesn't influence what I said about the water heater.

I've been using a similar one about three times a month during my brew sessions for over a year now, I've never had a problem. So long as you have a GFCI outlet you'll be fine.

It saves me a ton of time getting to a boil on my gas stove top.

Edit: Now comparing this one to mine, I realize this doesn't utilize a ground prong (not sure if that matters) nor does it have the safety shut off if it's out of water, so this thing will cook as long as it's plugged in, brewday cattle prod anyone?
