||This ingenious and simple device
works with your thermostat to
heat a forced air home more efficiently when the home uses a
wood or gas stove for auxiliary
heat. You set the ThermGuard to
turn on the furnace blower at
specified intervals and duration.
The furnace blower then periodically circulates your auxiliary stove
heat throughout the house without turning on the furnace heat. This can reduce
your heating bill by hundreds of dollars and make your home more comfortable.
