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.
The heat in the apartment is electric.
Heat can be generated using both gas and electric sources. Gas heat is produced by burning natural gas or propane, while electric heat is generated by passing electricity through a heating element.
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.
Go with the gas heat.
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.
