how many feet do I need to heat 20 degree Fahrenheit for 2.5 gallon of water?

I don't know if that is answerable. Would depend on ambient temp and other factors. My guess is 1 or 2 feet max though. The aquarium heater I have in a 40 gallon tank is only 40 watts and it cycles on and off and can raise the temp 20 degrees above ambient I think without being on all the time. So for just 2.5 gallons I wouldn't think you would need very much @ 20 watts per foot.

I use it for heating water in the winter time to work with tile. I don't know exactly the heating range. It works really fast. I fill up 3/4 of the 5 gal bucket and is hot in 20-30min.

I have the 2.5 gallon model under the bathroom sinks. It works very well. The owners manual doesn't show the max temp on the thermostat. The highest setting is not numbered. It says Max. I did find some specifications on line for the 6 gallon which stated the max temp was 140 deg. Jim

I have two pannels for 5,000 gallons, and it is not that warm, you should use around 6 pannels

To test the unit I connected it to an outside faucet. I filled a 5 gal bucket in 1 min 10 seconds. Incoming water temp 52 degrees. Outgoing 136 with T Stat set to 140. Water psi set to 28psi.

I would venture a guess of 5 ft. I have used it at 20 ft and it gives me a good idea as to what I am looking for. My main reason to purchase it was to find where cold air was coming in. I found the worst spots and then fine tuned it from there. Hope this helps.

If The room Temperature starts at about 60° it will heat the room about 2° an hour. You can feel the heat blow About 2 feet away from it. I use two heaters to heat my thousand square-foot home

150000-200000 btu minimum. Higher if you are not using a solar cover at night to retain heat. I have 250k btu on 17000 gallons and it heats the water very rapidly.

I use 2 sets (4x20) for my 5,000 gallon swimming pool. On a sunny summer day, the water temperature will go up no more than 10 degrees. I also use the solar bubble blankets at night to keep the water warm.

It won't work for your application. This heater is meant for indoor tanks. For 200gal at 20F you'll need some sort of de-icer.

You need apr. 2 ft of copper or gal. on each side of water heater, I had pvc and cpvc to mine to start and the cold side melted and burst, the copper will cool down before heat reached the pvc, Carl

This item must be used for a 5 gallon bucket (or tall 3 gallon size) or larger. Best for 5 gallon size as larger would take much longer to heat. It does not have a temperature control or on/off switch. Best not to plug in to electric until you have a bucket full of water and then either unplug when removing or transfer to a 2nd bucket. Height of unit is slightly taller than average 5 gallon bucket so wiring always stays outside bucket to avoid electrical shock. You can regulate heat by using a thermometer if need be or the touch(water not element) test. I use mine to heat water for carpet cleaning extraction machine so precise temperature is not critical. Hope this helps:)

If your other hot water heater is a good distance from where you will be placing it, it will raise the water leaving it about 20 to 25 degrees, so be careful and watch for skins burns, but as long as you aren't putting it real close to the hot water heater I didn't have no problem.

Heating a 3500 gallon pool you should use the 18 or next one smaller. Heating a 35000 gallon pool you will need the 27. Keep in mind the electrical requirements. The 18 draws 150 amps. The 27 will require additional electricity that most homes are not wired for. Hope this helps.

The boiling temp is 212, it takes about 15 to 20 min. Steam is not too much.

I am pretty sure it will be warm enough to meet your needs. I just measured the steam directly at the exit and it was 108 degF before my thermometer maxed out. I dont have any other means of measuring it. However in order for the water to be made steam, it has to boil it at 212 degF and the temperature will drop rapidly as it carries up into the room. So my best guess is it is somewhere around 120 deg F directly at exit and nearly room temperature by the time it is a foot or more away. Hope that helps.

i would get a 300 W heater for a 55 gal. I believe the general rule is 5 W per gallon of water. 200W isn't quite enough.
