When the lights go out, it’s natural to worry about what else might stop working – especially your boiler. Whether you have a combi boiler, system boiler, or conventional set-up, a power cut can indeed affect its performance.
How Does a Power Cut Impact Your Boiler?
Most modern boilers—whether combi, system, or conventional—rely on electricity to power internal components such as the timer, thermostat and pump. While they may burn gas or oil to generate heat, they still need electricity to function. Therefore, a power cut will typically stop your boiler from working until electricity is restored.
You may notice:
- No heating or hot water
- A blank or flashing display
- Fault codes after the power returns
Once the power is back on, some boilers automatically reset. Others may require manual restarting or fault code clearing.
Will It Damage My Boiler?
Generally, a power outage won’t damage your boiler. However, sudden power surges—either during the cut or when electricity returns—can cause internal control boards to fail. It’s worth considering a surge protector to help reduce this risk.
If you suspect an issue after a power cut, don’t attempt DIY fixes.
What Should You Do After a Power Cut?
Here are a few practical steps:
- Check the display – Is it blank or showing a fault code?
- Try resetting your boiler – Refer to your user manual for specific instructions.
- Check other electrics – Ensure the circuit breaker hasn’t tripped.
- Inspect your thermostat – It may have reset and needs reprogramming.
- Wait it out – If the power flickers on and off, allow stability before attempting a reset.
If your heating still won’t come back on, we recommend booking a boiler service in Tonbridge to ensure everything is operating as it should.
How to Prevent Future Issues
While power cuts aren’t always predictable, there are steps you can take to minimise their impact:
- Install a battery backup or uninterruptible power supply (UPS) for your boiler.
- Regularly maintain your boiler to catch electrical faults early.
- Consider a smart thermostat with backup memory to retain settings.
Don’t Wait for a Breakdown
If your boiler regularly struggles to restart after outages, it could indicate deeper electrical or control issues. Our boiler repair team in Tonbridge can help diagnose persistent faults and recommend suitable solutions.
Stay Warm, Even When the Power’s Out
In summary, yes—a power cut can stop your boiler from working, but it doesn’t always mean something’s wrong. Understanding the connection between your boiler and your home’s electricity supply can help you stay one step ahead of cold showers and chilly evenings.
