    Default Conversion from gas furnace to electric furnace

    Is there an easy way to convert a gas furnace to an electric furnace?

    Thanks in advance

    It is quite easy. You tear out the gas furnace in its entirety. Then you pay an electricial quite a bit of money to upgrade your service and install a very high-amp 220 circuit to the furnace location. Now you purchase a brand new electric air handler, and have the electrician hook it up.

    Sorry to be a bit brusque, but there would be no such thing as a "conversion"

    In Israel's climate replacing a gas furnace with an air source heat pump (ductless or ducted) would be far preferable to a resistance-electric furnace, since you'd also get the benefit of air conditioning. The average efficiency of heat pumps will be quite high in heating mode in that climate too, EXREMELY efficient if you get a better version with continuously variable speed compressors/blowers, using only ~20% of the average power of a resistance-element furnace. Most apartments & houses in Israel could be heated and cooled reasonably with a single ductless mini-split.

    there are such a unit and it called a duct heater. you install a metal sleve in you duct past supply and install duct heater, the right size wiring for rating of heater. stat for electric heat, because your stat is for gas. there is a drifferents. and that about it. code here say 12in before and after heater. we installed them all the time in geothermal units. but heat pump would save you 2/3 and maybe more to use.

    A co worker of mine had an electric plenum heater (i think that was the term)installed on his fuel oil furnace. In this area with electric at .04 off peak per kwh he saved more than the cost of the upgrade in his 1st year. Now if your on natural gas I dont know if it would pay. Certainly if you have fuel oil or propane it might be worth a look.
