Heating Problems - Boiler Advice - Heating Tips
Here are some some basic boiler checks you can do before calling a plumbing and heating engineer. Simply follow the checklists.
If you still have any concerns after having carried out these checks feel free to contact us to arrange a visit - a phone call can put your mind at rest.
- Gas Boilers
- Is there gas to the boiler?
- Check using another gas supply in the house - perhaps a cooker or gas fire?
- Check that the gas supply valve is turned on at the gas meter.
- Does the boiler have a pilot light?
- Is it alight?
- No - Refer to manual for lighting procedure. Re-light pilot and observe. (Instructions may be printed on the reverse of the boiler front panel).
- Yes - If the pilot light is lit but there's no heating or hot water you will require a visit.
- Does the boiler have electronic ignition?
i.e. no pilot? Is a spark present?
Use eye-view to check inside boiler.
General Heating Tips For All Boilers
- Is the electricity supply on?
Check the boiler supply switch is on.
Check the fuse on the boiler supply switch and replace the fuse if necessary with a 3amp fuse.
- Is the programmer or timer switched on?
If in doubt, switch to "override", "constant"or "continuous".
- Do you have a wireless room thermostat?
Try changing the batteries in the room unit. You may need to reset the unit by following the manufacturers instructions.
Gas Combination Boilers
- Is the water pressure adequate?
Check the pressure gauge on the front panel or underneath the front panel shows between 1.0 - 1.5 bar. This may have dropped if you have recently bled your radiators.
If the pressure is too low turn off the boiler, locate the filling loop tap and top-up to required pressure.
(This may be a chrome flexible hose under the boiler or on more modern boilers or alternatively built into the pipework under the boiler).
- Is the boiler particularly noisy?
Yes - if you have a combination or system boiler, check the water pressure guage, as described above. If you have a regular boiler, check the header tank (the small one) in the loft has water in it. The ball valve may be stuck and the tank is empty.
- Are radiators hot at the bottom but cold at the top?
Yes - This means they need 'bleeding' using a radiator key or suitable tools. After bleeding radiators re-check the the boiler pressure and increase as requied.
If you feel tired and experience tightness across the forehead, headaches, weakness, dizziness and nausea when a gas appliance is in operation switch the appliance off, open widows and call a plumbing and heating engineer
