Since hybrid car technology exists, I wondered about the availability of hybrid home heating systems. It seems to me that this might be a viable option for homes in areas that have cold winters and rainy spring and/or fall seasons.
There is a system called a Dual Fuel system. This is a heatpump and a gas unit in one. Once the temperature gets too cool for the heat pump side, the gas kicks in.
Carrier call its system hybrid.
