Cold radiators reported by guests in a holiday cottage
The property
A brick holiday cottage near the river, let by the week, with a combi boiler and radiator pipes under a timber sitting room floor.
The problem
Guests mentioned cold radiators, and the cleaner kept finding the boiler gauge near zero between bookings. No sealant had gone in.
How we found it
With upstairs valved off, the downstairs circuit still dropped. Once warm, the thermal camera picked out a hot streak between two sitting room boards, and tracer gas came up through the same gap.
The outcome
The owner saw our photographs of the marked point, agreed the quoted repair by phone and had it done while we were there. Payment was by bank transfer.
