Avoid common mistakes when buying a new radiator

Five things to consider:

1. Hydronic vs Electric

Firstly, it’s important to buy a new radiator that matches your heating needs as well as the electric or hot water system that’s in place. In addition, the radiator should match your interior. Hydronic radiators are ideal for maintaining a comfortable indoor climate throughout the entire building and are available in a wide range of models, such as panel radiators, design radiators, towel warmers and various kinds of convectors, so that it’s easy to find the perfect fit your interior. Electric radiators, on the other hand, are great for creating occasional heat in, for example, bedrooms, bathrooms, hobby rooms or places where there’s no central heating such as a basement or converted garage.

2. Size

Once you’ve figured out the best kind of radiator, it’s vital to determine the right size so that it meets the exact heat requirements. If you buy a new radiator that is too large, it takes up more space and doesn’t work as efficiently. However, if it’s too small, the radiator cannot meet the heat demand and the room won’t reach the set temperature.

There are other factors to consider, such as the dimensions of the room, the degree of insulation, the number of outer walls, the size and glazing of the windows, etc.

3. Positioning

Another consideration is the position of the new radiator(s). They are often installed below a window, both to counteract the cold air and draft and to minimise the loss of available wall space. However, depending on the kind of radiator you choose, this might not be the best idea. Especially if you choose a panel radiator, you need to make sure that there’s sufficient free space around the radiator and there’s no furniture blocking the radiant heat. Radiators should always be installed at a distance of about 15cm from the floor and at least 10cm below the windowsill.

Fan convectors are ideal where windows are floor-to-ceiling, or for window base areas. With rapid heat up time, low unit heights, and wall and floor bracket mounting, convectors are perfectly suited for this application.

Tip: if you need a radiator in a room with limited wall space (eg. small kitchen or bathroom) consider a vertical design radiator. This kind of radiator takes up very little space and the minimalist design ties in well with any interior décor.

4. Valves

Just like you need a tap to get running water in your kitchen sink, you’ll need the right valves to control the heat output of your new radiator. So make sure you don’t forget to buy the right radiator valves for your hydronic radiators. Depending on how your pipework is installed, you’ll need angled radiator valves or straight valves. Also think about the look you want to create so that you pick the right finish for your thermostatic head.

5. Balancing

A final mistake you’ll want to avoid when buying new radiators is a lack of professional hydraulic balancing. Only this allows the radiator to get exactly the amount of water you need to meet the room’s heating demand, so ensure you have the system balanced by a qualified professional.
