Solar Thermal - Can you link to a combination (combi) boiler?

Combi boilers, which provide instantaneous hot water as soon as a hot water tap is opened and central heating without a storage tank, are now very popular in the UK. In short, the answer is yes, but it is not a typical approach as to generate hot water from a solar thermal system requires a hot water storage tank. It is possible to install a solar thermal system with an unvented cylinder or thermal store, suitable for providing pre-heated water to a combi boiler. Unfortunately the vast majority of existing combi boilers in the UK will not accept the pre-heated hot water from a solar system so further investigation is required to check if the boiler in place is suitable.
