WIll heat pump work in NJ?
Reading heat pumps are mostly for places with mild winters. Need inputs from pros. Also, what alternatives which are less on utility bills work over and above the standard gas fired furnace, except geo.

It is possible to have a heat pump and a gas furnace. When the temps get down where the hear pump cannot keep up, the system will automatically switch to the gas furnace. This is called dual fuel or hybrid heat in the industry.
A load calculation will need to be performed on the building and then the size of heat pump and electric heaters can be determined. With that information you can calculate the cost of kw versus the cost of a therm and determine which way would be more efficient, a furnace or an electric heat pump. And a dual fuel system can expand on the efficiency over just a furnace alone.If Guns Kill People, Do Pencils Misspell Words?

Heat pumps are great for NJ. I just installed a heat pump in the house I bought recently in Lancaster, PA. Tore out the oil boiler and am looking forward to paying less then half as much to heat my house this winter.

Isn't electric heat always costlier than gas based heating? Sorry, but I don't understand why someone will augment a gas based heating with electric heating with electric heat being stage 1 and on extreme cold auto switching gas heating. Please forgive me for asking this, but need to understand the concept. Also, is it possible to add an electric heat pump to an EXISTING gas based heating HVAC?

Heat pumps
will extract heat from the ambient air quite well if sized and installed properly.

You're confusing "electric heating" with heat pump heating. They're not the same, though a heat pump does run on electricity! Originally Posted by wisepole

While a heat pump is electric, it provides more heat for the money then most fossil fuels do. Originally Posted by wisepole

Am guessing I didn't give a good explanation. I'll leave it alone, am sure someone will be by to help clarify

A heat pump will work fine in new jersey. Just make sure the manual J your contractor takes your heating load requirements pertaining to your area into consideration.

They work fine in PA, so no reason they won't work as well in NJ.

heat pumps work well in NJ
being from jersey and servicing them alone the ocean for many years the only complaint was when the strip heaters kicked in the bill would go way up
had a heatpump with oil backup in my house and it saved me a fortune in oil cost
was set to 30 degrees then the oil furnace would kick on and the pump would shut off/
a hp is 450 percent eff at i believe 40 degrees and will give enough heat and comfor down to the balance point of your house also will work well with gass backup
my electric bill was about 120 for the month of janurary the coldest and was only useing 5galons of oil a week
average temp for central jersey is 40 degrees

electric resistance heat can only give you maximum 1 unit of energy out for every one in. A heat pump will give you 2.5 to 3.8 or so units of energy out for every one in depending on conditions and efficiency of the unit. Gas heat will give you anywhere from .75 to .95 or so units of energy out per unit in depending on the furnace. So you have to compare those efficiency numbers to the cost of the energy per btu. This will vary by location as well as whether or not you use gas for other things or just for heating. You have to take into account the whole cost and not just the cost per unit of energy (monthly service fees to have gas connected, etc.). Originally Posted by wisepole

With a Heat Pump/Gas system why are heat strips even needed at all? Originally Posted by beachtech
