The MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It will operate for up to 14 hours on a 20-lb propane tank. The MH80CV features a standing pilot, piezo push-button ignition, and 'insta-lock' chamber for easy assembly. The MH80CV comes ready to use with the included hose and regulator. It operates on a 20-lb or larger propane tank (not included).
There are a couple of other factors that may effect the time a 20 pound cylinder will last on a heater. Propane is stored in liquid form in the tank and must evaporate to be used in most heaters. The colder the temperature the propane tank is stored at the lower the pressure is in the tank. As the liquid propane evaporates it cools down the liquid propane still in the tank. As a result at minus -20 you might have a half full twenty pound tank and not have enough pressure to run the heater.
There is approx 100,000 BTU per gallon of propane. A 100 lb propane tank holds approx 23 useable gallons. So that is 2,300,000 BTU. If the heater ran constantly burning 25,000 per hour that would be 92 hours straight.
9.2 days to empty the tank.
That depends on how much water is drawn from the tank and how often it is drawn.
a standard 10 gallon tank is 20 inches long.
Assuming a roof with a depth of 1 inch, you would need a roof that is 3 725 799.02 sq feet. Assuming a square building, that would be 1930.23 feet per side.
It all depends on how much the tank holds and the wattage of your heater I like to have 10 wattage for ever gallon so if you hVe a ten gallon tan you need a 100 watt heater also the temperature of you want will make a deference normally my 20 gallon tank can go from 46F to about 77 F in two hours

guppys are tropical fish. they require a heater, and 1 gallon is to small for a heater
either a 15 gallon tank or a 20 gallon tank
it all depends on the amount of water you can usually get by with a 10 gallon heater
If the temperature is around 20 degrees (Celcius) probably not. But for a five GALLON fish tank, probably.
Yes. A goldfish can live without a filter. They may not live as long, but they do not have to have a filter, or a heater. I had goldfish in a five gallon tank without a filter for a long time. Hope that this helps.
The answer depends on the volume of the gas in the tank, temperature and the dimensions of the tank. As a rule of thumb, you could expect to develop 6,000,000 btuh at 40*
30,000 gallon tank at 60 % means there is 40 % left in the tank ( 30,000 times .40 is equal to 12,000 ) * so there is 12,000 gallons left in the tank
If your tank is too small for a heater it's too small for the Betta. The answer is simple. Get a bigger tank. A male Betta needs a heater, a filter, a light and living plants to be healthy. It grows to about 2 inches long so that means it needs at least 2 gallons of water ie a 3 gallon max capacity tank.
A 50 watt heater is major over kill for a 3 gallon tank, a 10 watt heater is more than enough for a tank that size. You will nuke your aquarium very quickly the first time the 50 watt heater sticks on, with a 10 watt heater if it sticks on the aquarium temp will only raise a degree or two.
I would not use a heater of less than 100 watts for anything. The price difference is minimal between 50 watts and 300 watts. Basically it is only the comparative physical size of the tank and the heater that decides how 'big' a heater should be. My usual surmise is "bigger is better" because it will not have to work as hard or as long as a smaller wattage one.
