How many would you need to heat a 60 Gal hot water tank?

Depends on how much wattage the hot water tank needs (VOLTSxAMPS)=WATTS. Also, don't expect to get the full 400W out of this unit.

According to Eheim, the following heaters should be appropriate:Model 3616 150W heater: 53-79 gallons (US)Model 3617 200W heater: 79-106 gallons (US)If your tank is in a room that gets very cold in the winter, you might want to go with the 200W heater.

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

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.

60,000 gallons of pool water weighs roughly 510,000 pounds a 400,000 btu heater running at 85% eff. would add approx. 340,000 btu's an hour. this translates to about 1 degree temperature rise every 1.5 hours of run time with your solar cover on, make it 1 degree temp rise in 2 hours without that solar cover.

I would recommend finding some higher quality heater for your 300gal tank. You could find a 1000watt heater or just run 2 heaters

A 40 Gallon should have a 200 watt heater... it's 5 watts per gallon is the normal requirement

Do some research, but the recommendation fr a 50-75w is ridiculously low. The minimum in a 30g tank would be 100 watts if you're just looking at a few degrees above ambient temperature. If you want to maintain more than five degrees above, then you should go with a 150 watts. Although it is more expensive to do, some people with larger tanks start looking at two smaller heaters, so maybe a 100 on one side and a 50 on the other, or a pair of 100s, so that your tank holds a reasonable temp if one fails and the wider spread of heating can help things even out better.

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.

The 50w model was designed for 6.6-15.8g aquariums. The full list of their heaters is listed here: https://www.eheim.com/resources/product//450/downloads/11/EHEIM_aquarium_heater_25_-_300_manual.pdf

A single 150 would work. These never get very hot but just put it where your have the highest circulation. I have mine next to a U4 submersible filter in my 50 gallon tank. Quite frankly, I keep my place warm/cool all the time, 68-80, so mine probably does not come on a lot anyway. If you have African Cichlids that would be different but I just have SAE, Platys, Japanese trapdoors, etc. which like it in the mid 70's anyway.

This model turns on the heater when water flows and adds 3500w of energy to whatever the incoming water temperature is. At 0.5 gpm the water temperature will rise about 45 deg, so if you begin with 60F you'll get 105F, but when the 120F water arrives it will jump to 165F.

IF you have a house that gets cold, say 50 degrees at night then I'd get a 125-150 watt, however most situations a 100 watt will do just fine. The larger heater will not over-heat the aquarium, unless you get a very large one , say 200-300 watt heater. The temperature of the water would not be held at a steady state and the huge heater would have a tendency to slightly overheat a little just because it is larger in size and has more mass to it. This would cause some cycling of the temperature.

add 2 fl oz per gallon of water for each 500 sq feet. when using a tank sprayer

The Aqueon is been unreliable for temp, I bought a Eheim heater and its holding temp well, for a tank your size the 300w should do the trick, rated for up to 250g

Tank size per manual is 800ml, seems like it runs 40-60 seconds with hot water...depends on pressure setting

You would need to have more than one but obviously need to on the same filter return. The only other way I could see is if you used a sump and had another heater in the sump and just used this one to heat the water as it returned to to the aquarium. From my personal experience I wouldn't waste your money on one of these. They don't even last 6 months before they fail.
