Hi. I am having trouble with my boiler firing up when the nest is calling for heating. It's happening intermittently at the moment which is proving difficult to locate the fault. So far turning the power off and on again is fixing it, however this is inconvenient as the boiler is in the loft. Any help would be really appreciated. My thermostat display is model 3.4 and the heat link is amber 2.5.
