Ducted geothermal?

i think they mean their heat pump uses air ducts to direct the airflow to to registers in each room as opposed to having a ductless system like a mini-split.

Probably. I know geothermal systems are always ducted and air source ducted systems are less common in colder climates due to being less efficient.

The heat pump runs anytime it’s above 20 degrees. Below 20 it uses a propane forced hot air through the same ducting. I burn about 500 gallons of propane per year and my average electric bill in the winter is around $350. Overall I spend the same to heat / cool my 2600 sq foot house as I did using an oil fired baseboard system in my old 1200 sq foot house. Also worth noting my old house has fiberglass insulation and my new home has closed cell spray foam.

That's not bad at all. Our house is around ~1800sq ft and we also use around 400-500 gallons of propane a year (combination boiler, gas range, and gas fireplace). I'm looking to add an R32 heat pump to our open first floor because we have a slightly oversized solar array. Have you received your January 2023 CMP bill yet with the 50% supply-side increase?

Sort of...I signed up for a community solar project, so 3/4 of my bill hasn't invoiced out yet. I've paid for 623 KWH of the 2165 KWH I used...I'm sure it will be high, but the savings from the solar farm should help stifle that charge.

ah, didnt know that. thanks for the info.

Yeah, it’s fully ducted heat pump with a propane forced hot air backup.

No, it’s a heat pump, but instead of having heads all over the house, it goes through a ducting system with a blower. Basically turns a heat pump into a forced hot air hvac system. Also acts as whole house AC in the summer.
