No Heating in Havant

All our technicians hold valid full gas registration and are qualified to diagnose heating failures in combi boilers, system boilers, and older back boilers common in Havant Victorian terraces.

We use flue gas analysers, manometers, and thermal imaging to identify why your heating has failed, whether it's pump failure, diverter valve issues, or blocked heat exchangers.

Available for no heating emergencies across the local area, surrounding neighbourhoods, newer housing developments, and surrounding areas. We understand how quickly properties lose heat in North East winters.

Fixed diagnostic fee covers the callout and fault identification. Any repair costs are quoted upfront before work begins, with no hidden charges for parts or labour.

Very common in the local area winters when temperatures drop below freezing. The plastic condensate pipe from your boiler freezes solid, causing the boiler to lockout for safety. Usually affects external pipes on north-facing walls.

Heating pumps typically last 8-12 years but can seize up suddenly. You might hear grinding noises from the boiler or find that hot water works but radiators stay cold. Common issue in properties around local suburbs and neighbouring areas.

In combi boilers, the diverter valve switches between heating and hot water. When it sticks, you get hot water but no heating, or sometimes neither. Particularly common in Worcester Bosch and Vaillant models.

Your boiler pressure gauge should read 1-1.5 bar when cold. If it's dropped below 0.5 bar, usually due to small leaks or recent radiator bleeding, the boiler won't fire up for safety reasons.

Older mechanical timers and room thermostats can fail without warning. If your boiler isn't receiving the signal to fire up, it won't provide heating even though the boiler itself is working perfectly.

Modern boilers show error codes on the display panel. Write down any flashing codes or symbols - this helps us diagnose the issue faster. Common codes include F22 (low pressure) and F28 (ignition fault).

The pressure gauge should read between 1 and 1.5 bar when the system is cold. If it's below 1 bar, the system may need represssurising. If it's above 2.5 bar, there could be an expansion vessel problem.

Follow the small plastic pipe from your boiler to where it drains outside. In freezing weather, pour warm water over the external section to clear ice blockages. Never use boiling water as this can crack the pipe.

Turn your room thermostat up to maximum and listen for a clicking sound. If you hear the click but the boiler doesn't fire up within a few minutes, the issue is likely with the boiler itself rather than controls.
