I was wondering if anyone would be willing to give me their thoughts on the necessary components & controls required for the following.
I have a 350l thermal store supplying, dhw, heating and an indoor pool with a gas boiler. There is a solar coil in the store and I have first fixed 15mm supply/return pipes to the roof insulated with armour-flex, plus a control cable. I was going to add 2 or 3 x 30 tube panels, heat can be dumped into the pool or I can easily add external radiator etc.
I figure I need a controller, pump station, expansion vessel but not really sure the best way for it all to work. Also, thinking it may be better to run the central heating with the boiler separately while having a back-up to keep the top of the store topped up for HW.
Appreciate any insights given, Raf.
