What to do if your central heating stops working

Cold days can be unbearable, especially when your central heating system decides to take an unplanned vacation. As the temperatures drop, the urgency to restore warmth becomes paramount. In this comprehensive guide, we’ll walk you through the troubleshooting steps and solutions to revive your central heating system efficiently.

Diagnosing the Issue

Check the Thermostat

One of the common culprits behind a malfunctioning central heating system is a faulty thermostat. Ensure it’s set to the desired temperature and replace the batteries if necessary. A programmable thermostat can enhance energy efficiency, providing both comfort and cost savings.

Here are some links to popular Thermostats and their troubleshooting guides.

Check the Thermostat

Inspect the Pilot Light

For gas-powered heating systems, a pilot light that’s gone out can disrupt the entire heating process. Follow the manufacturer’s instructions to relight the pilot. If it continues to extinguish, there might be an issue with the thermocouple or gas supply that requires professional attention.

Evaluate the Power Source

Electric heating systems demand a reliable power source. Check the circuit breaker and reset if needed. If the problem persists, there might be an electrical issue that mandates an electrician’s expertise.

Basic Maintenance Tips

Bleed Radiators

Air bubbles in the radiator can impede the circulation of hot water, leading to uneven heating. Use a radiator key to bleed the system and release trapped air. This simple task can significantly improve your heating system’s efficiency.

Book an Annual Boiler Service

Ensure the longevity and efficiency of your central heating system by scheduling an annual boiler service. Professional maintenance helps prevent breakdowns, identifies potential issues, and keeps your system running smoothly.

Technical Troubleshooting

Inspect the Circulator Pump

The circulator pump is crucial for distributing hot water throughout the heating system. Ensure it’s functioning correctly by listening for any unusual noises and checking for leaks. If issues persist, a professional assessment may be necessary.

Verify the Pressure Levels

Low water pressure can impede the proper functioning of your central heating system. Check the pressure gauge and follow the manufacturer’s guidelines to adjust it accordingly. If you’re unsure, consult a heating professional.

When to Seek Professional Help

While some issues can be resolved through DIY efforts, certain situations demand the expertise of a professional heating technician. If it’s a Gas appliance that has the issue, ensure you find a suitable Gas Safe registered engineer. Consider professional assistance if:

  • The issue persists after basic troubleshooting.
  • There are strange noises or leaks in the system.
  • Your heating system is old and requires a thorough inspection.
