what as the cost of heat for a 1200 square foot home in 2004
No. The compressor is needed to run in reverse in order to pull warm air from the outside to heat the home.
No, the amount of BTUs needed to cool a house is different from heating it. Cooling typically requires fewer BTUs because it involves removing heat from the indoors to maintain a lower temperature, while heating involves adding heat to raise the temperature.
The electricity needed to heat a house typically comes from the grid or a local power plant, not from a generator or a dry cell. Generators are usually used as backup power sources for temporary or emergency situations, while dry cells, like batteries, are not designed to provide the continuous high power output required for heating a house.
A 4 ton heat pump should be fine, depends on how well your house is insulated. If the house is well insulated you might be fine with a smaller unit.
36000 Btu
That's going to depend on . . . -- the starting temperature of the water -- the target temperature of the water -- how fast you want it to get there -- the efficiency of the heater you use
Heat energy leaves the house due to convection, conduction, and radiation. Convection occurs when warm air rises and is replaced by cooler air, carrying heat energy out. Conduction transfers heat through direct contact with colder objects like windows and walls. Lastly, radiation allows heat energy to escape as infrared radiation through windows and gaps in insulation.
There are 23 gallons in a 100lb tank that I use to heat my pool.
