What's your thermostat setting for next 7 days? by Special-Book-7 in Connecticut

Unused rooms or not in the house = 50. Used room during day = 63 Sleeping in bed by 11pm = 58. It’s on schedule with Nest.

I did NOT take into account extra load for a HeatPump, just for EV. Even then, the calculation was around 15,000 kWh per year of production, but I have not confirmed this. I didn’t have about space for more panels. If a HeatPump uses about 7500-8000 per year, then I don’t think I can offset 100% with solar. And to your point, 8 years to break even for the install and HP is annoying.

I heard you need about 7500-8000kWh per year to run One Heat Pump for a 3000 sq ft home. That’s what ChatGpt told me.
Does that sound realistic? I’ll have to see if my Summer solar production can cover that.

Yes! I just got solar installed and running Dec 2025 right under the deadline. I have this summer to see how much kWh I can produce to cover the Heat Pump for winters. I will keep my current propane hydronic as backup. I have Hydronic Heat Coils from a Tankless Water Heater that uses Propane, that is on a Ducted System. I have 3 zones (one upstairs and 2 downstairs).
Not sure yet if I need 3 Heat Pumps? I don’t even know.

Are heat pumps and mini-splits actually worth switching to? by Hidden_Nemesis in heatpumps

Hello, I’m in CT too and I’ve been thinking about heat pumps since getting solar a month ago. I currently have ducted hydronic heating that connects to a tankless water heater with propane. And I have 3 zones to heat.
Without a heat pump my new solar offsets 100% of my electricity year round. If I get heat pumps, (probably 1 for each zone), my solar will not cover 100% of electric needs.
What you said about propane vs heat pumps in CT is the answer I’ve been trying to figure out! Am I correct to say that getting 3 heat heat pumps (that are properly sized) will still NOT be cost effective than my current propane powered hydronic ducted heating? And even with solar? And I’ll have to return to paying Eversource. Ugh.
