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.

How long will 30000 btu heater run on a 23 gallon tank?

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.


What is electric water heater which used in house?

An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.


How long should hot water from a 40 gallon tank last?

The dip tube in a water heater is a long plastic tube that extends from the top of the water heater to near the bottom. It is designed to carry cold water to the bottom of the tank so it can be heated by the heating element or burner.

You would switch on an immersion heater to heat the entire tank. It is designed to heat water in tank systems by immersing in the water and heating it directly.
