Central Heating Radiator Guide

Choosing the right radiator can often be a tricky task so we have built a tool to help you in your search for a new radiator. By entering your detailed requirements for any room of your household into the PlumbNation Heating Calculator you will be instantly notified of the Watts / BTUs required to heat that room. Not only will you be supplied with super-fast heat loss results, the Heat Calculator will also recommend suitable radiators needed to satisfy those results, which will help greatly in narrowing down your search for the perfect radiator required. Please visit our radiator BTU Calculator page to begin.

Central Heating Radiators are designed to emit heat by radiation and convection. Heat is emitted via a convector or fin behind the initial radiator panel. This convection provides the majority of heat, with a small amount radiating direct from the steel panel,delivering greater efficiency and a more even heat distribution throughout the room. stock one of the largest range of sizes, styles and outputs, which vary depending on a variety of differing factors. It is important to ensure that the radiator chosen is sufficient in size to adequately heat the room in question. From the simple standard and compact product to the more contemporary decorative designer radiator, we have a huge range available for you to browse and purchase today. 

There are three main types of Panel Radiator that you are likely to come across whilst browsing our collection, and these are as follows: 

  • Single Panel Single Convector  (K1 / Type 11)
  • Double Panel Single Convector (P+ / Type 21)
  • Double Panel Double Convector  (K2 / Type 22)

The essential difference is the size and the amount of heat it generates, therefore when you know how much heat you will need for the desired room and your size restrictions you will then have a good solid choice for the ideal radiator solution. Single Panel Single Convector Rads consist of one front steel panel, and one convector or fin. Double Panel Single Convector Rads consist of two steel panels (one front, one back), and one convector or fin. Single Panel Double Convector Rads consist of one steel panel, and two convector or fin. Double Panel Double Convector Rads consist of two steel panels (one front, one back), and two convectors or fins. Triple Panel Triple Convector Rads consist of three steel panels, and three convectors or fins.

The output is measured in British Thermal Units per hour (BTUs/hr). For any given room you will need a radiator with a sufficient heat output capacity to heat that room to a satisfactory temperature level. If too small, you will not reach the desired temperature level, by choosing one that is too large you will be paying more on energy bills than you need to, thus wasting energy and money. 

Compact panels are perfect for use in domestic central heating systems. The LST Radiator is commonly found in hospitals, schools and retirement homes. They are now becoming increasingly popular within the domestic market, most commonly for nurseries, child bedrooms and disabled occupants. Every home with a priority for the latest design and home fashion trends available you'll find our Designer Radiators collection to have everything you could ever ask for. Buying a Electric Radiator is probably the easiest and most simple way to heat a room. As they will not be connected to a central heating system there no need for a costly installation. Simply plug your Electric Radiator in and enjoy the warmth they provide. However energy costs over a period of time may amount to more than that of Central Heating systems.

To complete your central heating system we have a huge range of radiator accessories, Thermostatic Radiator Valves allow you to set the room temperature as required. You also can turn the TRV down completely if you are not occupying the room in question, thus conserving energy and saving you money on your energy bills.A Thermostatic Radiator Valve is most commonly referred to as a TRV. A TRV can be fitted to your radiator to give you ultimate control of your heating system. Thermostatic Radiator Valves enable you to control the heat output on a room-by-room basis. A TRV uses a sensor to establish the surrounding air temperature. The TRV will close down the flow to the radiator, thereby cooling and generally regulating the room temperature.If you are looking for heated towel rails commonly found in bathrooms, we have a dedicated category for all towel rails. All Radiator Fittings and Feet are available for each radiator.
