<p>The apparatus comprises a thermal store such as two tanks (12,14, figure 1), a combination boiler 31, an additional energy source 6 and a controller 19. The thermal store and combination boiler are each arranged to selectively provide hot water for a domestic hot water (DHW) system 32 or for a space heating system 33,34. The controller allows control of the thermal store and energy source to provide DHW and hot water for the heating system. In a first aspect the energy source is a non-fossil fuel energy source such as a heat pump, wind or solar power and the controller automatically controls the thermal store and combination boiler. In a second aspect the thermal store utilises a phase change material and the controller permits user interaction to control operation. In a third aspect the thermal store and energy source are mounted externally of the premises. A method of forming a hybrid heating apparatus is also claimed. The apparatus permits use of the additional energy source to heat the thermal store such that the thermal store is used to meet DHW or space heating demand where possible with the combination boiler meeting any shortfall.</p> |
