How to choose between them
Heat pumps move heat from the air, so they cost far less to run than gas, but their output falls as the air cools. Size with the heater calculator: BTU per hour = gallons x 8.34 x degrees of rise / hours.
Larger models need a 230V circuit; check the maker's electrical requirements before ordering.
Rankings follow the rule and order stated above, using makers' published specifications and listed prices. How we research · Disclosure
