Lovely job George. Delighted it worked out well, did you get it finished prior to the mini heat wave?

On post #23 the the circulating pump is shown in a vertical orientation. Most pump manufacturers specifically discourage this. But, it should lie horizontally.  facepalm

Just seen the later pics with the new pump fitted correctly.

I like the “dual use” aspect of this project. But I am a bit worried about how you plan to prevent the pipes from freezing in winter.

Phillip- well spotted -pump has been corrected.
To prevent pipes freezing -the house heat exchanger is just inside the wall so both the pool and house circuit are short. As soon as ive fitted the house heat exchanger and checked for leaks i shall drain and refill with a glycol or similar mix.
I intend to lag the pipes also but probably  not the pool pipes as heat loss in summer will be minimal.
