Oil/HVAC Hybrid

You can use heat pump at moderate weather, and use a steam system as a back up/auxillary heat source for colder weather.

Hello
Does anyone have information on energy savings if retaining a recently installed oil boiler for steam heat, and switching to heat pump for hot water/cooling?

Really need many more details to offer any sort of advice. How big is your home? Is your existing hot water heater oil-fired? How new/efficient is it? I can tell you that in my home (single family, 4 occupants), the only remaining oil-fired equipment we have left is our water heater and it sips oil in comparison to our oil-fired heat furnace. More specifically, since decommissioning our oil furnace in November 2022, we’ve used less than 250 gallons of oil on hot water. I know this because November 2022 is the last time I took an oil delivery, when we filled our 250-gallon tank, and as of this post, we still have more than 50 gallons left according to the gauge. That leads me to the conclusion that a fairly efficient oil-fired hot water heater might actually be less expensive to run than a heat-pump water heater, and when factoring in the high cost of heat pump water heaters + installation, permits, etc., is certainly a LOT more costly than maintaining our oil equipment. Funny enough, NYSERDA recently inspected out home because we got some state rebates for home energy up grades, and the inspector from Honeywell said that with present options on the market, he wouldn’t recommend an air-source heat pump for hot water.
