Radiators are designed to emit heat by radiation and convection, with the majority of the heat emitted via a convector or fin. These convectors are assisted with a small amount radiating direct from the steel panel for greater efficiency and a more even heat distribution. Radiators come in a huge variety of sizes, styles and outputs, so it is important to ensure that the radiator chosen is sufficient to adequately heat the room in question. Radiators on sale in the UK today include everything from simple standard radiators to contemporary designer ranges. You can choose from Single Panel Single Convector radiators, Double Panel Single Convector, Double Panel Double Convector, LST (Low Surface Temperature) or Fan Convector radiators in numerous shapes and sizes. Single Panel Single Convector radiators consist of one front steel panel with one convector or "fin". Double Panel Single Convector radiator consist of two steel panels and one convector or "fin", Double Panel Double Convector radiators consist of two steel panels and two convector or "fins", LST (Low Surface Temperature) radiators provide the perfect solution where a low surface temperature is required for safety reasons, and Fan Convectors can also be connected to your central heating system just like a radiator for high heat outputs where space is limited. Heated towel rails are an alternative to radiators and can provide that extra feel of luxury to your bathroom. Wet System towel rails are run via your central heating system and function in the same way as a conventional radiator.
Thermostatic Radiator Valves can be fitted to most radiators giving complete control of your heating system by enabling you to control the heat output from the radiators on a room by room basis, thus conserving energy and saving you money on your heating bills. You can buy Thermostatic Radiator Valves from manufacturers such as Danfoss, Honeywell and Drayton, then retro-fit to an already installed radiator. Thermostatic Radiator Valves come in several sizes to fit the existing plumbing pipe work on your radiators, common sizes are 8mm, 10mm or 15mm. Plus you can purchase packs which include adaptor sizes to fit all pipe sizes.
There may be many reasons as to why you need a radiator service, from simply taking the radiator taken off the wall for decorating, replacing a radiator for cosmetic purposes, or updating your radiators with a more efficient design for more comfortable heating. A Gas Safe Register plumber or heating engineer is best qualified to work out the right type of radiator for you in terms of heat output. Radiators should always be placed in the coldest part of the room, which is usually below a window and on an outside wall. As a general rule of thumb, the larger the size, the greater the heat output.
The average price to do a simple radiator change (ie a straight swap new for old using existing pipes) is around £50 to £80 and includes fitting Thermostatic Valve. To flush all radiators in an average central heating system costs around £500. A complete central heating installation including boiler plus 8 radiators normally costs around £3000. To remove and refit radiators for access to decorate/plaster would typically cost around £30 per radiator. The cost to fit/install a Thermostatic Radiator Valve (including draining down, supply and fit, refill the system and bleed all radiators) is around £100. These are of course average costs and you will need to contact heating engineers in your area to provide quotations to get the exact cost for your heating job.
