A heat pump is 3x more efficient at heating than a resistive electric heater, making it just about a wash with a gas furnace in most markets in terms of sustained cost. The hardware is more expensive, but not THAT much more expensive. When you include installation costs and amortize over a 20 year system life, the overhead is non-zero but quite low (10% or so). If you guess that gas is going to be more expensive in the coming decades where electricity is futureproof, it seems like a good bet to me. Ask me in 20 years.
- xani_ 4y agoI wonder how's the failure rate compared to oldchool types of heating. The longest warranty I can find on the market is 10 years
- ajross 4y agoThe moving parts are identical to an air conditioner. Those go for decades reliably.
- xani_ 4y agoWe had 2 in our office closet datacenter and they definitely needed more maintenance than what I remember our coal burning furnace did
- LurkerAtTheGate 4y agoLived & owned homes for 20 years in an area where ASHP are standard installs as the climate range meant 100% of normal (outside of freak polar vortex) heating and cooling was covered by the heat pump. Inexpensive part failure is common annually - usually capacitors and fan motors. Usually expensive part or system failures occur around 10-15 years.
