As the weather heats up over the summer, your industrial heating takes a backseat for a few months. If your factory or warehouse is closing for summer, or you’re switching off the office heating and turning on your cooling system, it’s the perfect time to service your heating.

1.      Get ahead of any maintenance issues

By checking your heating system whilst it’s not being relied on, you can get ahead of any maintenance issues that need addressing before the cold weather comes back around.

And if you’re considering upgrading your heating system, our free site survey is a great way to find out what your ideal solution might be – at no extra cost to you.

2.      You’ll be seen more quickly

Generally speaking, heating engineers are less busy in the warm summer months. This means you’ll have a better chance of quickly getting booked in with a heating system repair service.

3.      You could save money

If your heating system needs repair, it’s always much cheaper to get it sorted out ahead of time. If it unexpectedly breaks down in the depths of winter, getting a heating engineer out to perform an emergency repair is likely to be much more expensive.

Top tips for maintaining your heating system this summer

1.      Bleed radiators and check boiler pressure

Any air left in your radiators over summer could be drawn up into your boiler or heat pump, causing potential overheating. It can also cause internal corrosion within your heating system, potentially damaging crucial components and leading to costly repairs.

If you’ve got any radiators in your heating system, you probably won’t be using them at this time of year. This makes summer the perfect time to bleed your radiators – and check the pressure of your boiler too.

2.      Top up your corrosion inhibitor

Corrosion inhibitor protects your heating system from rust and corrosion. Without inhibitor in the system, shards of metal will gradually flake off internally, blocking up pipes and preventing your radiators from getting hot when you turn them on. Top up your inhibitor to prevent this, or contact a heating service and maintenance provider to do so.

3.      Fully open your TRVs

If any of your radiators are controlled by individual thermostatic radiator valves (TRVs), this step is very important.

When your heating system is turned off over summer, TRVs close down and prevent any water flowing through the pipes. If you leave your TRVs turned down to the low position, you might find once summer has ended and you fire up your heating system again that these TRVs are stuck in this position. This is a problem, as a radiator with a stuck TRV won’t get as warm as it should – and will need fixing by a plumber. To prevent this, keep your TRVs fully open throughout the summer months. This is usually done by turning them in a clockwise direction.
