Let’s talk Radiators

In News by Thea Vermeulen

Radiators are by far the most common form of heating in a home. During the colder months, you need your whole property to warm quickly and stay that way. They must always be free of air and full of water in order to function well.

Radiators Operation

  • If you notice a cool spot on the radiator, particularly towards the top, it could mean that air is trapped inside. An air release vent on the radiator allows you to release the air using a special air vent key. (Watch this video on how to bleed your radiator).
  • If you have a sealed heating system (one without tanks in the loft) then make sure that you know how to check that the water in the system is at the right pressure and how to top up the levels if it’s not. It is important your installer has shown you how to do this.

Thermostatic radiator valves (TRVs)
Radiators should usually be fitted with thermostatic radiator vales, this will allow you to alter and control the temperature of each of your rooms. This can also provide a simple way of reducing running costs.

  • It is important to make sure that the area around a TRV is kept clear and is not blocked by furniture or curtains so that it can accurately detect the room temperature.
  • To prevent TRVs and on/off radiator valves from sticking, turn them a little by hand every 2−3 months.
  • It’s also important to check that the plastic tops on all valves are always in position and are not cracked or damaged to prevent accidents.
  • TRVs should not be fitted on a radiator in the same room as a room thermostat. Electronic radiator thermostatic valves (eTRVs)
  • eTRVs provide time and temperature control, enabling every room to be easily controlled for your comfort.
  • Each eTRV controls a radiator valve to regulate the heating in the room, based on time programmes, set temperatures and how the room is used. This potentially provides an energy saving of 25%. Even radiator heat Radiators should heat up at the same rate. To ensure that they do, your installer should have balanced the system. This can be done by adjusting the lock shield valve, which regulates the water flow.
