Optimal Thermostat Setting for Air-Source Heat Pump
Hi good folks,
We’ve got three air source heat pumps in our old house, here in the suburbs of Boston. Each of the ASHPs is matched to it’s own outdoor unit. We’ve been told to “set it and forget it” for the ASHP best efficiency. We have therefore set the thermostats to 62 degrees Fahrenheit.
However, 62 degrees is too warm for sleeping under blankets and too chilly for eating dinner, unless you’re really bundled up.
So how is everyone else dealing with the thermostat dial? Does everyone with ASHPs live with the “set it and forget it” model? What temperature do you set it and forget it at?
Note that we are trying to use less power here to heat the house. We are attempting to get as close to zero fossil fuel use as we can, with solar panels and ASHPs and a wood fireplace insert.
