All the heat pumps that I know of are electric. Some may have gas backup-- in
very cold conditions , heat pump will not work, so some kind of backup is needed.
yes
Yes, as long as it a gas system and not a electric heat pump system
An electric heat pump can heat up your home during winter and cool it during summer.
Go with the gas heat.
There are to many variables to effectively say but gas generally costs less than electric and older electric would use even more than new electric.
That depends on 1- where you live (climate) and 2- what the gas and electric rates are in your area. If the gas rates are low and you are in a cold climate I would.
the electric fuel pump.
An electric heat pump needs heat available to pump. If it is 30 degrees outside, heating a spa to 102 or so, may be impossible unless the heater has some type of alternative heat source. A properly sized, gas fired heater can take care of a larger range of heating needs. A combination heat pump and natural gas heater, probably with a controller, really makes the issue more difficult, expensive, and would require a lot of study for efficient, cost effective operation. Bottom line: In really mild climates a heat pump might do the job. In cooler climates the gas heater rules. And where a wide range of temperatures and high heat demand is wanted by the customer, a gas heater is the only way to go. A backup heat pump may take years to payout. HM Louisiana
That will depend on the cost (and availability) of gas in your area, when compared to electric costs. It will also depend on the climate. At very cold temperatures (below 40 F) the heat transfer element of an air/Freon heat pump does not deliver heat, and the less efficient electric heat kicks in. In a climate that has long periods of below-freezing temps, a gas furnace may be more economical to operate.
Fuel pump in a Fiero is electric. It's in the gas tank. Gas tank's in the middle of the car. Drop the tank. Pull the pump.
depending on conditions but generally a heat pump will cost you less to run.
Heat pump is more efficient. If you use electric heaters, 1 joule of electric energy will produce 1 joule of heat energy. If you use heat pumps, 1 joule of electric energy can pump several joules - perhaps up to 5 or 6, depending on the outside temperature, and the efficiency of the heat pump - of heat, from the outside to the inside.
