Thermal stores allow multiple heat sources to be connected in a number of different ways, with immersion heater(s) back-up. This makes it possible to have a gas or oil fired boiler connected to a solid fuel appliance and also a renewable heat source such as solar thermal or a heat pump. Furthermore, underfloor heating system manifolds as well as radiator circuits can also be directly connected to the store.
