Hi:
We have a 1930s Cape Cod in MD. It has a natural gas boiler for
radiators, and a heat pump/central AC system. The two systems are
controlled by two separate thermostats. My question is, can I get a
single thermostat which will allow me to control the two systems so I
can be as energy-efficient as possible? Around here it gets cold enough
so that the heat pump will doubtless fall back to its aux heat, which is
quite inefficient. What I'd like is to use the heat pump when it's not
too cold out, then switch over to the radiators as the aux heat. Can I
maybe wire the heat pump thermostat so that it kicks on the gas rather
than the resistance heat? Any ideas would be appreciated.
Thanks,
Freud
