Boilers & Heating Repair Tips
Before you call:
Check you have electricity
If you have any light showing on the boiler then you have electricity.
Check you have gas
Make sure that the meter valve is open and also that the valve under the boiler is open. If you have a gas hob or cooker, check to see if they are working.
Check the pressure gauge
It should be between 1.0 – 1.5 bar.
If you hear ‘sploshing’ sounds and your boiler sounds like a washing machine
During Winter, the white or grey pipe outside may have frozen. Boil a kettle of water and pour over the whole pipe until it thaws out.

My radiators are hot at the bottom and cold at the top
That’s air trapped in the top of the radiator. Follow the instructions below to vent the air out of your radiators.
How do I vent my radiators?
- Do this when radiators are cold
- Get a tea towel and a vent key
- Make sure pressure at boiler is 1.5 bar
- Bleed downstairs radiators first
- Apply vent key and hold tea towel near the vent
- Open the vent by turning the key anti-clockwise half a turn
- If water appears, shut the vent, the radiator is ok
- If air comes out of the vent, wait until water appears then close the vent.
- Go back to the boiler and pressurise to 1.5 bar again.
- Repeat steps 1 – 5 for all downstairs radiators
- Repeat steps 1 – 5 for all upstairs radiators
Do this at least once a year.
My water is working but doesn’t seem as hot now it is winter?
Quite simply, the temperature of the water entering your boiler is a lot colder (average 6c) than it was in the summer (average 15c). Turn up the hot water temperature on the boiler and turn down the flow of your hot water tap more. This will show if the water gets hotter by going through your boiler more slowly.
Fit a room stat if you haven’t got one already. Your boiler will use less energy than it would without one.
Ideal room temperature is 17c-22c. Try turning your ‘stat’ down 1c and see if your house is still comfortable to live in. You may be surprised to find that it probably is!
Put on extra layers of clothing before you actually turn up heating. Insulate your loft well and keep heat inside the house instead of paying to heat up the sky..
In rooms that you don’t use as often, i.e. bedrooms, turn down radiator thermostats to ‘number 2’ and keep the door shut. You only need to keep the chill out of the air. Most people can’t sleep well in a stuffy or excessively bedroom anyway.
Fit reflective sheets behind radiators so that heat reflects back into the room rather than unproductively heating up the wall behind the radiator.
