Falling boiler pressure in a chalet bungalow
The property
A chalet bungalow on the village edge, with bedrooms under the eaves and a solid ground floor. Thin copper heating pipes run in the screed to each radiator downstairs.
The problem
The boiler had to be topped up every couple of days. The heating engineer had checked the boiler and radiator valves, found nothing, and suspected the floor.
How we found it
A pressure test, isolating each circuit in turn, put the loss downstairs. Once the heating was warm, the camera traced each thin pipe across the floor to a warm smudge in the hall; tracer gas agreed.
The outcome
Our mark went on the hall floor, with photographs. The owners used their own heating engineer for the repair, who opened the screed only at that spot.
