Now the weather has cooled down slightly we’ve noticed the radiators aren’t coming on. Anyone able to offer advice? My wife is wearing two jumpers and threatening divorce if I don’t sort it out?
We had the boiler replaced a few years back. There is hot water and the underfloor heating is working in the kitchen (fed by the central heating). But the radiators aren’t getting warm.
I’ve bleed the radiators, repressurised the system, reset the boiler, turned it off and left it half an hour, cleaned out the Fernox and still no heat.
As the underfloor heating is working I’m assuming the thermostat is to blame – is the only way to test this to buy a new one and swap it over?
Any thoughts if it could be anything else? Diverter valve?
Is it get a plumber out time (or an electrician)?
