Preparing your boiler for winter: the practical guide

The arrival of autumn marks the ideal time to prepare your heating installation before the first cold. A well-prepared boiler guarantees a warm winter without surprises.

Why prepare your boiler before winter?

Avoid breakdowns at the worst time

Heating technicians are overwhelmed with calls at the first frost. A boiler breakdown in the middle of winter can mean several days of waiting in the cold.

Optimize consumption

A dirty or poorly adjusted boiler consumes up to 20% more than a perfectly working appliance.

The owner's checklist

1. Check circuit pressure

Your heating circuit pressure should be between 1 and 1.5 bar when cold.

2. Bleed the radiators

Trapped air in radiators creates cold zones and reduces heating efficiency.

3. Check the thermostat

Test the proper functioning of your thermostat and replace batteries if needed.

Conclusion

Preparing your boiler before winter is a simple gesture that saves you a lot of inconvenience.
