How long until hot water? Debating between this or 2 1/2 gal tank heater.

Depends on how you intend to use the water. Our usage is for making tea, coffee, hot coco so we use 2-6 cups X 6 ounces and there is plenty of water for refills. Make sure to set the heater to desired tempature. Quart = 32 oz, 1/2 gallon =64oz. I have never ran out of hot water. The water is delivered via 1/4 inch hose so its too slow if you need a large quantity of ho water.

Hot water is instantaneous. Since it's on demand it doesn't heat and continually keep 2 ½ gallons of water hot all the time this saving energy. This is my second one and highly recommend it.

It only takes a few seconds for us to get hot water. Ours is used in the kitchen for hot chocolate, tea and to fill pots so they don't take so long to boil on the stove.

Patricia you asked a difficult question because recovery depends on 1) size of the tank 2) the temperature of the cold water input 3) the voltage on your network, but... my ballpark figure is around 45 minutes, that is if you completely depleted all hotwater. Using water a bit here and there, you'd never know there is a recovery as the thermostat kicks in the moment you start using hot water and the temperature has dropped a few degrees in the tank.Hope this help? I have five of them and would not be without them, also purchased them for our Church and I haveabsolutely NO CONNECTION with Amazon, Bosch or anyone, just like you a customer, me a happy one!HGM Patricia you asked a difficult question because recovery depends on 1) size of the tank 2) the temperature of the cold water input 3) the voltage on your network, but... my ballpark figure is around 45 minutes, that is if you completely depleted all hotwater.

The unit does not have a water tank - it uses an in-line water heater. If you use the power-saver setting, water is only heated when you're sitting on the seat (it takes 15-30 seconds for the water in the unit to heat up), and the maximum amount of heat depends on the cold-water temperature coming into the commode.

After the unit warms up (5-10 mins), it kicks out PLENTY of heat at the lowest wick setting. I've never tried keeping it at a higher setting because I haven't needed it. If you're warming <2000 sq ft, this unit can handle it at a low setting. Tank is 1.9 gal and gets me about 12 hours of heat, so north of 6 hours per gallon I suppose.

I haven't timed it, but if the water is hot is happens pretty fast.. I'd guess three to five seconds.

Hello RaeRae, You answer is not so simple. The capacity of a heater not only depends on the heater itself, but the original temperature of the medium. Even though this is rated for a larger tank than you are asking about, if the place the tank will be in much colder than average is may be a good choice. If your water starts at 65 degrees, and you want it at 78, this may work for you. If you start at 72, this may get the water hotter than you want. Another aspect to consider is how much water movement you have in your tank. The more water movement, the better the heat will be distributed, and the water will be closer to the thermo's temp setting. I agree with JR, I have not seen any for that small of a size. You could look at reptile heating accessories that afix to the outside of the tank, it would be a hack though.

I installed this unit last February. I have a 375 gal tank and home only uses gas for the Rinnai and my home furnace. Over the summer/fall when my furnace is not in use, the gauge barely moves on my tank. My best guess is that a 20 lb tank would last 2 months. Consider what fittings and connections you might need because the typical 20 fitting for a grill might not give you enough flow for the Rinnai.

Unplug the unit and take it to the sink, pour the old water out then take the unit apart, I use about a Tablespoon of vinegar mixed with about a cup of water take an old wash cloth and wipe around the inside, it will have a built up of water deposit around the heating element and where it get's really warm at, I take an old toothbrush or cotton swabs and try and get as much off as I can but you won't get all of it off and that's ok. and pour a little of the cleaning solution in it then rinse all out of everything. I do this once a week. To keep the water deposit from building up use distilled water. Then fill the tank up and it's ready to use. Hope this help's.

This dual-bottle Mr. Buddy heater (the big buddy) has higher BTU than the smaller single-bottle heater. On high, I don't think I ever got more than 5 hours out of a 1# bottle. I think the manufacturer includes some sort of specification, though. Check your user guide. For me, I use 20# tanks, not 1# bottles except in an emergency. The 20# tanks seem to last forever. The key is, the heater really heats a space. You don't need to leave it on for a long time. Just turn it on, bring your space up to temperature, then turn the heater off. For my 200 sq foot mini-cabin, with vaulted ceilings, this typically takes 10 minutes -- a few minutes to come up to temperature, and a few minutes to make everything really toasty and hold that temperature so it lasts. I've never tried to time a 20# tank -- I'd heat myself out of the cabin if I tried. So in winter, a 20# tank lasts about 2 weeks, and is usually 1/4 to 1/3 full when I take it down the mountain for a refill. Hope this helps. - tkh If you're using this heater, you're either car camping or using it in a stationary camp. In which case, a 20# tank is the best way to fuel the heater.

I would go with at least the 50 watt. Probably the 100 would be better. You can always put it a little bit diagonally in the tank. it is ok to fully submerge even the top part. I would consider going with 2 50watt heaters with one on either end of the tank for a more even heating effect. Plus both heaters would last longer because neither one would have to work as hard.

3/4" should be just fine, it is not up to code, and you will get less than the listed power, but it will work fine to replace an 80 gal storage tank.It takes 52K BTU to heat 80 gallons by 77 degrees, with a 70% efficient water heater. With a 'first hour' rating of 120 gallons it is 78K BTUYou can get 79K BTU at the end of 100' of 3/4" pipe (or equal, with fittings). Code for this heater would require 1" for a run of more than 10'As a note, the efficiency listed is a best case running full power.

Hi Gary, my water pressure is about 80 psi at home and haven't had a full tank, half at best (maybe 20 gal.). For me about 5-8 minutes for the black tank. Even if it would take 3 times that, it is worth it not waiting in a long line at the campground.

Hello. I wanted to start by noting the heater I received is not the one in the picture. It is shorter and thicker, and only has one suction cup at the top.That said, I bought this one because it was the lowest wattage I could find for my 1 gallon tank. The recommendations I found said 7 watts for 1.5 gallons and up, 5 watts for 1 gallon and up. I have not seen any for smaller tanks than that.

This is based on my Primus two burner camp stove. Boiling 3 qts of water takes 15 min and uses 1.4 oz of propane. The 1 gal tank fill is 4.25 pounds or 68 oz giving 728 full burner minutes. My estimate for cooking dinner for 4 is 40 full burner minutes or about 18 dinners per tank. Breakfast for me is maybe half that and I don't cook lunch so 60 min per day gives me about 12 days. If you cook more, estimate burner minutes per day to figure how long 728 will last. Hope this helps.

On. But your heater will stay on all the time then... Unless your going to push the button everytime you want hot water, but depending on how often that is you may not have very hot water. I would suggest letting it heat two hours in early AM and two hours very late afternoon, this is what we do and with two people in house we always have hot water and it has saved us a lot of money on electricity. Good luck

Even the 10,000 btu Unit says it takes a 100 gallon tank. You'll also need a 3/8 male to 1/2 inch adapter to even connect it with a shutoff valve. If you need a small space heater for bbq tanks, buy a top tank unit. They will burn for about 29 hrs on a tank, but they're also dangerous.

Just measure your space, and ask the expert at the big box store to select. My concern on the 4 gal unitis, "is this enough hot water for you".
