We just replaced our entire HVAC-oil-furnace stack,
and elected the heat-pump option instead of a simple
AC compressor. I've been taking some performance
measurements, e.g. with Tout = 45 deg, it takes the
heatpump about 1 hour to raise the house temp by 2
degrees. It consumes 5kW, so that's 2.5kWh/deg.
Whoa, we'll be using far more electricity than our
roof makes! The default outside-temp breakpoint
for switching to the oil burner is 40 degrees.
I'm studying the thermostat manual's installation
instructions to change to 50 degrees. They claim
heatpump heating is cheaper than oil, but I doubt
it! Anybody have experience with a hybrid system?
