Boiler Running but No Hot Water or Heating? Here’s What to Check
It’s a frustrating situation: your boiler is running, but you’re not getting any hot water or central heating. Don’t worry, there are a few simple checks you can do before calling out a professional. Here’s a step-by-step troubleshooting guide to help you get your heating and hot water back on track.
1. Check Your Thermostat and Timer
First, make sure your thermostat is set to the desired temperature and that the timer is correctly programmed. Sometimes the settings can be accidentally adjusted or reset, especially after a power cut. If your thermostat has batteries, check they haven’t run flat.
2. Is Your Boiler Getting Power?
Look at your boiler’s display panel. If it’s blank or showing an error code, check the fuse box to see if a switch has tripped. Reset any tripped switches and see if this restores power. Also, check the power supply to the boiler itself.
3. Boiler Pressure Levels
Most boilers need their pressure to be within a certain range (usually between 1 and 2 bar). If the pressure is too low, your boiler may not function properly. You can usually top up the pressure using the filling loop, but always follow your manufacturer’s instructions. If you’re unsure, it’s best to call a professional.
4. Pilot Light or Ignition Issues
If you have an older boiler with a pilot light, check to see if it’s gone out. Relighting the pilot light is sometimes simple, but if it keeps going out, this could point to a more serious issue. Modern boilers may show a fault code if there’s an ignition problem.
5. Other Common Causes
- Frozen condensate pipe: In cold weather, the pipe carrying condensation from your boiler can freeze, causing a blockage. Thaw it gently with warm water.
- Airlocks in the system: Air trapped in your radiators or pipes can stop hot water circulating. Bleeding your radiators can help.
- Faulty motorised valves or pumps: These parts control the flow of water in your heating system. If they fail, you’ll need an engineer to replace them.
