Central Heating System Leaking Under Floor

[GraRob]

Whilst searching for options around leak finding I’ve come across both thermal imaging and using UV dye in the system.

You can hire a thermal camera from some tool hire shops. No idea if they are good enough or if a layman could be successful.

Thanks for that. I actually have my own very expensive thermal (rifle) scope, which is pretty good. I may try that. It's a Pulsar Trail.

Pulsar Trail.

Serious kit!

Range finder OK? even to 1,000 Yards???

Yes, can see pretty good animal heat signatures to well over 1000M. At the sub 500M range, the clarity is very good. Loads of YouTube videos.
The range finder is just "ok" it's a comparator using typical animal sizes - deer, fox, duck etc. But good enough to be within a couple of metres.

Dunno what it will be like in a house mind. May be too close.

If a leak is in a screed or behind a plasterboard wall a thermal imaging camera sometimes works if the pipes are below a well insulated floor as in newer builds it wont work

My thermal was no use, too close. I'd need to be few hundred yards away. Pipes under the floor were just a huge heat plume.

Was well worth a try.

Who the heck buys Vokera nowadays

Many combies worse than Vokera. I Always find them to be quite reliable and not bad quality.
