It’s my whole house heat pump system one-year anniversary this week. 🥳
2300sf Victorian in upstate NY, previously heated with wood and propane, now with Mitsubishi air source mini splits.
Power use, previous 12 months: 8,576 kWh.
12 months w/heat pumps: 14,902 kWh.

Rough envelope math: At $0.14/kWh (NYSEG West), let’s say it costs me $900 a year to heat and cool my house in the comfy high 60s.
Pre-heat-pump cost of wood and propane, while working hard at relying mainly on the wood and turning the heat down to 55 at night: ~$2500.

System payback time: About 10 years, if you assume the furnace would’ve lived that long, and if you don’t count the labor involved with the woodstove or the dramatically increased coziness.

The propane industry is scared for a reason.

There’s a lot of grumbling out there about how the grid isn’t ready for state electrification goals.
Reality: We will need more power generation, transmission, and grid resilience work even if NYS abandons its goals.
People will buy EVs and heat pumps because they make sense.
