Hydronic System Maintenance Tips

Your boiler is the central component of your hydronic heating system. To ensure that your boiler is operating at optimum efficiency at all times, it’s important to have a Hunt Heating specialist service your boiler every 1-2 years.

A regular service, preseason, is a preventative measure that reduces the disruption to your system during the colder period. This will ensure that your boiler can run smoothly and safely for many years to come.

With only 5 weeks until autumn now is the best time to implement money-saving measures to ensure you are fully prepared for the return of the cooler weather.

At Home Maintenance Tips

Hunt service experts recommend the following tips for basic boiler maintenance:


Bleed the radiators

If your radiators are cooler at the top than the bottom, air is likely trapped in the system. You, therefore, need to release the air by ‘bleeding’ the radiators. If you don’t, the system will not work as efficiently as unnecessary strain will be put on the system.

Switch the heating off before you bleed the radiators and slot the key into the bleed valve. Turn the key anticlockwise for a quarter of a rotation and you should hear a hissing sound as the air escapes. When water starts to drip (have an old towel or some kitchen paper on hand!), lock the valve and the job is done.

Check the water levels

If a boiler’s water levels get too low, it may not be able to deal with the heat it can produce. Ensure the system is filled up, when necessary.


Check external boiler occasionally, over the spring and summer period, as it is not unusual for small critters to make themselves at home

Thermostatic Valves

It is recommended that while not in use all thermostatic heads should be opened all the way to ensure longevity.

One of the best ways to maintain your hydronic system is to arrange an annual service, where your installer will check for faults and ensure your system is kept in top condition. If you experience a problem with your hydronic system that can’t be fixed via the steps above, then it’s time to call in a licenced hydronic heating and cooling professional.
