I may have to look for a leak on a heating system losing pressure every day. No sign of a visible leak anywhere, including prv and condense in case heat exchanger is knackered. All ground floor heating pipework is in concrete flooring, has anyone hired a thermal imaging camera and had any success in pinpointing the leak or leaks with one?

i have few times recommended specialized company who uses thermal imaging and they found leaks with success, its just so expensive to even hire :/ it would however cost more to try to investigate and use even borescope so this was cheaper option for customer.

thought of isolating gf pipework fm boiler then seeing what happens
Thats what I did last time capped off the pipes leading to down stairs rads and when pressure held over 48hrs bingo. Repipe downstairs rads.

cheaper than hiring thermal camera
I have already ruled out the boiler, I know its a system leak. Losing pressure every day, no sign of any water through the ceiling. Plastic pipe in concrete floor on ground floor which has already had 2 leaks repaired. The leak is in the concrete floor, I just don't know how the best way to find it is. It not a simple re-pipe as there are about 14 rads downstairs and would have to lift expensive wooden flooring upstairs to get at pipes for drops so would end up being very costly.

best get your thermal camera on the walls as well then, best get the customer to get in touch with their insurers, it could be very costly
It really is. It is under a BG contract and they have said they will no longer work on the system as it has cost them too much or some load of old crap. They want it sorted and I want to try and offer the best solution to help them out. Thermal imaging was all I could think of to pinpoint the leaks to repair and then pressure test before going down the extremely costly route of a re-pipe.

they need to contact their household insurance as you may be ripping up floors etc, forget bg insurance

So this would be the third leak under the floor? Is the best option then not to repipe. Sounds as though there is an issue with the pipes in the floor. The insurers may fork out this time, but might not be so keen for anymore. Just my two penneth.

hence why the insurers need to be involved now or custards will be left high and dry in the future, unlike their floor

all depends on the loss adjuster and what they say. reducing the risk of future damage must also be considered

If they have got 14 rads downstairs then it sounds like they can afford to rent a thermal camera!
I doubt there that pricey these days, the technology & price is coming down these days. Just explain it to the custard, and let them choose. Otherwise shut upstairs rads and get 3 bottles of leak sealer in there...

I wouldn't be entertaining a repair at this stage. They obviously need all the existing plastic removing from the system.
