In-roof tanks are well known for their longevity due to them mostly being made from copper which is very resistant to corrosion. The Rinnai Roofmaster system has inlets and outlets to connect to solar collectors as well as a wood fire. Some Roofmaster models come with a built in calorifier, which is a mains pressure coil fitted inside that draws heat out of the main body of water in the tank and exchanges this heat to this water flowing through the coil.
