    Had a call from the tenant today, the house was re-wired last year with heat alarm on ceiling approx 2m from boiler and heat alarm links to smoke alarms around the house. The tenant says that when the boiler/heating goes on the smoke alarms all go off. Any ideas please? could it be a faulty heat alarm? Boiler is on its own circuit as are smoke alarms.

    A modern room-sealed boiler generates very little heat from the boiler casing itself, so either you have an extremely over sensitive detector, or something else is at play. Are there any interlinked CO detectors?

    No there are no Carbon Monoxide detectors, just a heat alarm and three smoke detectors

    Swap the detector then, I guess. It's hardly going to break the bank. Assuming it's a fixed heat detector and not rate of rise, I find it hard to believe that the CH could be setting the alarm off, were it working properly.
