Positioning Your Radiator:
What’s the best positioning for my radiators?
Traditionally, radiators are placed in the coldest part of the room. This is typically under windows or near doors. Modern homes are better insulated, meaning radiator positioning matters less, and radiator positioning can be determined by aesthetics and available space.
How far apart should I space my radiators?
A general rule is to have one radiator every four metres (14 feet) in every room. This rule isn’t set in stone, especially as radiator shapes and sizes vary.
Are two radiators always better than one large radiator?
Yes, especially in larger spaces. The more radiators you have, the more evenly heat is distributed throughout the room, resulting in greater efficiency.
What clearances do I need above and below a radiator?
It is recommended to allow 100mm below and at least 50mm above each radiator to prevent heat blockage and allow heat to be efficiently distributed around the room.
Radiator Maintenance:
Why is my radiator cold at the bottom?
This is usually due to a build up of sludge, dirt, or rust in the system. Bleeding and draining the radiator usually fixes this problem.
Why radiators make noise:
Clicking radiator noises are caused by the metal contracting and expanding as the radiator heats up or cools down. This is typically nothing to worry about.
Banging radiator noises are typically due to kettling. Kettling often occurs in hard water areas, where limescale builds up within the system and blocks the pipes. Boiler technicians can be called out to fix this issue.
Gurgling radiator noises are commonly caused by air in the system. You can use a radiator key to loosen the radiator valves, then wait for the air to escape before closing the valves.
