Natural Gas System

This simple diagram pretty well describes the systems in our new home that will be powered by gas. The exception is the range, which will be electric. Also, we'll have two gas furnaces, one on the main floor and one for the daylight basement. The main floor system acts as a backup for a Lennox Heat Pump. The heat pump will be the primary heating and cooling system. However, when the temperature drops below the heat pump's ability to operate as efficiently as the gas furnace, the gas furnace will take over until the temperature rises enough for the heat pump to operate more efficiently.

The photos below trace the plumbing for the gas appliances from the supply and meter outside the east wall of the garage, into the garage, to the main floor furnace on the back garage wall, then the mud room, kitchen, through the east kitchen wall out to the deck to provide for a gas BBQ, then across the ceiling and down to the fireplace, and down to the furnace and the Navien tankless water heater in the storage room of the basement.
