Under Floor Central Heating Leak

[old wrinkly]

Friends of mine have recently moved into a bungalow with concrete floors.

They have converted from oil to naturnal gas and have a new Pottern Condensing boiler ( I think that's correct, they have no hot water tank) in the loft. Sorry don't know model.

The boiler was only installed about three weeks ago but it keeps locking out.

Potterton have inspected the boiler and says there is nothing wrong and it must be a leak under ground.

They have asked me if I know how they can detect the leak and also how to cure it.

I've had to confess I have no idea so hope that someone might give me some guidance I can pass onto them.

Thanks

Cut and cap to find the leak, but I wouldn't bother, it'll leak somewhere else sooner or later, cos the concrete gets to the copper and corrodes it. With a bungalow just repipe the lot with drops from above

Not sure I want to be on the end of the phone when I tell my friends, they were cooing as to how nice it was not to have any pipes on shown.

The pipes would have been laid when the bungalow was built, circa 1960, so assume they would not have been put into sleeves to prevent corrosion.

Would I be right to think that because they have a condenser boiler, which works on a pressurised system, this is why the leak has come to light. It may have been there sometime but the old oil boiler would not have been affected.
