The pool water won't generally have concentrations of chemicals enough
to damage the heating system directly (humans swim in it). However,
the risk would be from oxygen being continuously introduced into the
heating circuit. This would typically cause problems with iron and
steel components - e.g. boilers and conventional radiators. UFH
pipes, from what I've seen are either plastic or copper wrapped in
something to protect it from the concrete. You could confirm that.
I would expect that flushing it through with fresh water and refilling
would be adequate. There might be some accumulation of rubbish from
the pool if the filtration wasn't working.
I you want to replace the heat exchanger, you have an excellent local

think you have reached that point.
True, but you do get to have artsoppa on Thursdays, koettbullar with

Luckily, the underfloor heating doesn't work unless you close the
valves to the pool. (The water would just have pool temperature.) It
also appears the valves for the heating have been closed when the pool
was heated. Therefore, oxygen and pool chemicals should only have been
introduced when they switched between pool and underfloor heating.
That's wonderful news!

The standard heating in Sweden is electrical radiators, but this house

was almost unheard of in Sweden when this house was built a few years

electric heating. There are also connections for solar collectors, but
no solar collectors. Additionally, it looks like the house is prepared
for air conditioning and/or air heating.
Again, that's great news.
Yes, bills were expected and the price was a bit lower than it would
have been if the house was finished and didn't have any problems. But
