Why does my boiler fire up randomly?

Why does my banality fire upwards randomly?

If y'all're concerned that your boiler seems to have adult a mind of its ain, peculiarly if information technology's firing itself up all the time, it could mean there's a problem – or it might be completely normal. Allow's have a await at what it might be.

What causes a boiler to fire upward on its ain?

If you accept a combi boiler, it volition regularly turn itself on and off, specially in the winter.

That's because it provides hot water on need, rather than overnight every bit with conventional boilers.

So if the cardinal heating thermostat tells the banality to start upward, it will. And if someone turns on a hot tap, the boiler will starting time too.

To test information technology, turn your thermostat down and don't employ any hot taps for a while. If you lot prepare your main thermostat as low every bit it will go, the banality should never need to heat upwardly the radiators, and then it won't turn on.

Is information technology still firing up? At that place could exist a trouble.

Potential causes and solutions

Check your banality'south documentation to meet if information technology has a "pre-heat" wheel. This warms the water in the organisation so you'll ever have a fair amount of hot water when you turn on the hot tap.

Information technology should do it once every hr or two, and each fourth dimension will last a couple of minutes. Once again, this is perfectly normal, so you don't need to practice anything.

If it's turning on regularly then turning off, and doing this repeatedly, that'south more likely to signal a fault. It could be a component, such as the rut exchanger or an internal thermostat, in which case y'all should not effort to set up it – phone call a gas engineer who will be able to assess the state of affairs and recommend a repair or replacement. Making sure your boiler has its almanac service should prevent this stop-get-go blueprint.

Similarly, if your water pressure is too high, the boiler might exist shutting down for safety reasons. One time everything cools and the banality re-starts, information technology will fire upward for a pre-estrus wheel. Check your pressure on the gauge, and if it's far above 1 bar, drain a radiator until information technology reduces to around that level.

Your main thermostat in your home is basically a switch that turns the heating on when information technology detects that the temperature is below your setting, and off when the room warms up by that temperature.

If your thermostat is in a drafty identify, or somewhere with regular temperature changes like a front door or near to a washing machine, it won't be getting realistic measurements of the air temperature, and will switch the boiler on and off all solar day.

If you have a portable thermostat, make sure it'south in a living room or deep inside the hallway. If it's fixed to the wall, yous might accept to look at having it upgraded or moved.

Finally, modern boilers have electronic circuits on them, and although they're pretty basic, they do sometimes neglect, and might demand replacing or having new software installed. At that place's nothing regular homeowners tin can do in this instance – call united states out.

Still no luck? Speak to a team of professionals

We can't emphasise enough how important it is not to attempt to fix your boiler yourself. Gas, h2o and electricity can be a dangerous combination, then it'due south vital that you lot go professional assistance if you lot're concerned about how your boiler is performing.

Firing up is normal behaviour, just if information technology's over curt durations and without any specific input from you, you should get in impact so nosotros can have a expect.
