A thermal heating store is essentially a large water tank that is well insulated and connects to the hot water system. It is not the same as the hot water cylinder but it does use the water from the heating system. Usually made from steel, the device has the ability to store heat and is great for use in solar thermal systems and biomass installation.
Biomass boilers are normally heavier than normal boilers so they take longer to heat up and cool down. Solar heated water also takes time until the sun has produced enough heat to warm the water. The boiler flows and returns water from the thermal heating store and the heating system is connected to the store. In turn, the thermal store becomes the middle man component of the whole system, the buffer between the boiler and heating system. Once installed it is possible to introduce a range of heat sources from solar thermal to biomass as well as fossil fuels or electricity. When installing these methods with a thermal store, the heating system should not have to be modified.
Thermal stores help to make your home more efficient and can even out the usage of hot water throughout the day. It can release stored up heat during the peak demand times and will store extra heat in the low demand times. Your boiler and heating systems take most of the total electricity used in the household so it is important to make it as efficient as possible to save energy and money.
