How often should you check your LST radiators?

2 May 2019

To maintain a safe heating system at all times, it’s important to check your LST radiators are up to their full standard. Contour discusses when you should check your LST radiators and why it’s important.

If you suspect that the heating is taking too long to warm up and the radiators aren’t getting up to temperature, or if the radiator has cold areas where no heat is being emitted, bleeding them should be your starting point. LST radiators shouldn’t need to be bled very often, you should just check them once every few months.

If you notice a dark fluid when you bleed the LST radiator, this could be a sign that the system needs to be flushed as it indicates that there is dirt in the system that could be causing a blockage. A fully working LST radiator won’t have any patches of cold when the heating system is running fully.

Signs that the heating system needs to be flushed include the boiler sounding noisy, so it’s important to listen out for this when the heating is on.

Heating systems should only need to be flushed every 5-6 years and this is only for radiators over 4 years of age. If the radiator is under 4 and there are cold patches and a noisy boiler, it could be a sign of another problem. However, new LST radiators may only need to be flushed once every 8-10 years depending on the frequency of their usage.

In schools and hospitals, it’s important to service heating systems annually. In the winter, when plummeting temperatures mean heating systems are constantly in use, it’s important that they are up to standard to meet expectations on working temperatures.

Government regulations on health and safety for school’s state that classrooms should be at least 16°C. Checking your LST radiators before the winter starts is important, to make sure they’re ready for when you need them.

Plus, during the summer when the heating systems aren’t being used, it’s recommended that you check your LST radiator valves at least once a month to prevent them from getting stuck in place which could cause problems during the winter.
