This is something that is hyperthetical but i did wonder about.
I know a swimming pool is a heck of a lot bigger than a hot water service - but - for example - a friend has a solar hot water system that puts out near water at boiling point on a sunny day (faces NW).
Surely, if you were heating a pool with this temperature of water off a system, it would warm up to a tasty temperature after a day or so, without the hundreds of metres of black tubing that is prone to Cocky chewing, corrosion and high winds - and not take up as much roof area, so more room for things like solar panels and hws solar.
I reckon it would be more expensive to install to start with - but - then again - the one time we had the black tubing put on, it wasn't that cheap either.
Hmmmmm
