Solar heating of water and combi-boilers do not mix.The combi is
designed to operate on at least 1.2 bar mains water pressure, and water

Water heated by solar would not be able to be at this pressure? Why?

as it would have to be stored before delivery to the boiler.

It could be stored in a thermal store, with the supply to the boiler
being separate from the stored water.

What's the point? A combi boiler is specifically designed for
efficiency anyway.

1) A combination boiler burns gas, the price of which is going up
and is likely to continue going up.

2) The price of sunshine is not going up and is unlikely to go up.

3) Therefore it seems sensible to use sunshine as the fuel as much
as possible.
