Check the following:
1. IS YOUR BOILER WORKING?
Normally if there is a problem with the boiler it will display an error code (check boiler manual to see what this means) You may only have to reset the boiler – the manual will help you with this.
If you aren’t getting an error notice check your water, gas or electricity supply
Electricity supply: – check the power source-lights, sockets, main fuse box.
Water Supply: if no water is flowing from the taps this can impact your boiler.
Gas Supply: check other appliances that run off gas (fire-Cooker)
2. CHECK BOILER SETTINGS:
Check that the settings weren’t changed and that the hot water temperature settings is appropriate,
3. CHECK YOUR TIMER:
If the clocks have been changed it affects the boiler, any changes in power supply will also impact the timer.
4. CHECK DIVERTER VALVE:
(valve for switching between hot water and heating)
If your heating is working but you still have no hot water check to see if the diverter valve is set to heating alone. (a problem with the diverter valve will require the help of a professional gas engineer).
5. CHECK BOILER PRESSURE:
Low pressure can cause your water to not heat. Normal pressure for a domestic boiler is around 1.5 bar (you will find this on a gauge ‘Manometer’ located where the water supply pipes are connected to the boiler.
If the pressure is low go to your operating manual to re-pressurise the boiler. (if you are in any way unsure of what you are doing call a professional plumber)
6. CHECK FOR LEAKS
Leaks can cause all sorts of problems and most often happen at joints in the pipes, begin there or look for patches on ceilings, peeling paint, swollen woodwork or mould.
Leaks will cause a reduction in the pressure and can end up causing damp resulting in expensive repairs.
7. CHECK WATER SUPPLY – CONVENTIONAL SYSTEMS
Check to see if there is sufficient water in your header tank, is there a blockage stopping water refilling the tank.IS YOUR BOILER THE RIGHT SIZE FOR YOUR NEEDS?
8. YOUR BOILER THE RIGHT SIZE FOR YOUR NEEDS?
If you are having persistent problems, it just maybe that the tank is too small to serve your family needs.
