Heating and cooling

This is our heat exchanger (the grey box on the left) that will provide cooling in the Summer and heat in the Winter. It is connected to a heat pump on the outside of the building. When it gets below -10C, or if we need an extra boost of heat, the propane powered furnace takes over (the silver thing on the right). The system uses air which is either warmed or cooled and then distributed around the house through ducts. There is no mains gas where we live so instead we will have a huge propane tank outside the house.
