We recently moved into a 5 bedroom home in central Massachusetts with the following system that was installed in 2006:
- 3 zone hydro-air heat with Veissman Vitorond 100 boiler and Riello 40-F5 burner. Last test showed 85.5% efficiency
- 80 gallon Superstore ULTRA indirect hot water tank
- 3x First Co. 36HBXB-HW air handler with Heat Pump R-22 TXV installed, some zones are slightly smaller but they all have a heat pump according to the "installed with" label
- Nest E thermostats w/o any wiring for heat pump
- Electricity costs me $0.38/KWH - my total cost after delivery and fees
Heat pumps are all the rage, so I'm wondering if I should have the Nest thermostats wired with the heat pump for alternative heat, or if it wouldn't be a savings because we pay a lot for electricity?
