We have a pool with a walkable safety cover.
We have a heat source pump after years of heating it with a gas boiler.
Same. I've been here 15 years, bought both from new and have had to replace both. The pool was here (but near derelict) but I'd never get one.
The main reason being that the equipment breaks constantly (no matter how much you insulate it over winter, it's sitting in a shed in freezing temperatures). When everyone turns their pools on in May, there's an unholy demand for engineers to fix whatever's not working and you can end up paying eye watering fees.
Just a few examples - the first air source heat pump had a leak (not uncommon according to the engineer) so kept needing a top up. The electric pool cover ropes break most years so it's very difficult to open the pool until the engineer comes.
We have a robot cleaner but it never looks that clean as stuff constantly blows in from any trees in the area and the cleaner misses bits. It's a pain to open up and close down at the end of the season and fiddle around with the chemicals. We have some fancy machine that's meant to convert salt into chlorine but doesn't seem to work that well.
Yes, you're popular when your kids are at primary school or the odd weekend party but I have to nag my teenagers to use it. Off the top of my head, my heat pump costs about £400-500 per month in electricity (my pool is 11x5m and quite deep) so we're often paying £150 per swim.
The pool also only gets really pleasant when you have a hot spell of weather plus the safety aspect of other people's kids swimming. I'm always relieved when it's time to shut it down for winter....
