Radiator Buying Guide

When choosing a new central heating radiator for your home, it can be difficult to know where to start with such a wide variety. Planning ahead is fundamental and knowing what to look for will save you a lot of time and money in the long run.

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 the heat, with a small amount radiating directly from the steel panel, delivering greater efficiency and a more even heat distribution throughout the room.

At PlumbNation we have created a useful Heating Calculator which will generate a list of recommended range if radiators from the information and heat output you input. We help to narrow your search for the perfect model by notifying you of the Watts/BTUs needed to heat your chosen room. We include an array of types including flat panel, double panel, horizontal, vertical and column radiators. We stock one of the largest ranges, with a choice of various sizes, styles and outputs. PlumbNation.co.uk 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 panel product to the more contemporary decorative designer, we have a huge range available for you to browse and purchase today. 

From our Trade Range with a 10 year warranty that doesn’t compromise on quality, to the more contemporary decorative designer and cast iron models, we have a comprehensive collection available to browse and purchase for any heating system.

What are the valves and are they included?

Valves are not included with your radiator, generally. Thermostatic Radiator Valves (TRV) 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 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 rail.

How do I know what size I need?

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.

What type of Panel is best?

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 LST model 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 Radiator collection to have everything you could ever ask for. Buying an Electric model 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 it 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.
