They are supposed to give 4X for 1X when on the temps stated? They also claim that the inverter models can make even better and on colder temps?

Well I'm sure someone smarter than me will chime in here but I don't think that true. Electric resistant heat is 100% efficient, heat pumps are not.


Yes the resistant heater is 100 percent efficient but if you use that same amount of power to power a heat pump to extract heat from the air you will produce more heat than the resistance heater. If this were not true nobody would use one. The difference is where the heat is coming from. You are not creating heat with the heat pump, but taking it from the air and the warmer the air the more efficiently it will work.

There are heat pump hot water heaters too that use less electric than pure electric powered heaters for the same amount of heated water.

Well put franco b a heat pump doesn't make heat it uses refrigeration to move heat from outside to the inside. You know how a a/c units evaporator coil in the house removes heat from the air in a living space and dumps it outside that's why the condenser unit blows out hot air.

A heat pump does just the opposite of a a/c unit the evaporator is out side and the condenser coil is inside.

The fuel source for the heat is the air, it's not the electric. When you compress air and anything else that can be compressed you're also compressing the heat energy in it. If you want a simple analogy it's just like mining, instead of using a machine to mine BTU's in coal you're using a machine to mine BTU's from the air.

A heat pumps efficiency versus standard electric depends on the outside air temperature but it can be 3X as much, that's why they are given efficiency ratings higher than 100%.

I just don't get why you guys are debating this marvelous Reto-Fit Device that Tommy from St. Croix ,Minnesota(Northern Virgin Islands) has layed at your feet. I've been heating a 3 room 1800 Square foot Ranch home this entire past summer using only a Zippo Lighter hooked up to a railcar full of good 'ol Ronsol Lighter Fluid that Freetown Fred got me for Father's Day. Wife thinks I'm a Flamin' Genius ! Thanx,Tommy ! :crazy:
