Thermostatic or Manual - What is the Right Type of Radiator Valve for you?

Fundamentally valves can be split into two types Thermostaic or Manual (non thermostatic).  Thermostatic vavles allow you to control the temperatue of the room, manual are a simple on or off operation. Once you have decided on this there are several types of valves available and the right type for you will depend on how they connect to your pipework and your radiator or heated towel rail.

What are Dual Fuel and H-Block Twin valves for?

Sometimes, you’ll find that you need a radiator that can be used with your existing central heating system while also acting independently.

That’s what dual-fuel radiators do. With the radiator having an internal element that operates separately, a dual-fuel radiator valve needs to be able to adjust to the heat output from your standard heating and provide the right level of heat when the electric element is not in use.

The main benefit of these valves is that they negate the need to have new pipework carried out.

What Valve Size (Diameter) do I Require?

Most people don’t know that they can get different sizes of radiator valves. Mistakenly buying the wrong size could see you end up with a valve that won’t go on no matter how hard you try.

Now the issue isn’t because your radiator has a weird valve size but will be due to the pipes your radiator is connecting to being out of the ordinary. Most rooms in the UK have 15mm pipes as standard, but you may find a pipe to be 8mm,10mm or 22mm. The size can tell an interesting story about the history of a house and changes made throughout the years.

10mm RADIATOR VALVES


10mm radiator valves are usually needed when you have a single radiator which was added to your existing heating system. It’s not common for an entire house to have 10mm pipes, but having a radiator in the likes of a conservatory can sometimes see these pipes (and valves) needed.

8mm RADIATOR VALVES


8mm radiator valves are needed when a room or home has had microbore pipes installed. This was common in houses built in the mid to late 20th century, as it was seen as a cost and space-saving measure. The thinking was that smaller pipes minimise heat loss as water as you’re working with a smaller volume of water. Rather annoyingly, microbore pipes are more susceptible to blockages and kinks in the pipe.

22mm RADIATOR VALVES


22mm radiator valves are needed for your radiator to attach to a wider pipe. Wider pipes are generally used when the position of the radiator means it needs a higher flow of water. Sometimes you’ll find 22mm entries in the bathroom, as wider pipes were fitted to allow greater flow from your hot water tank to the bathroom.

What Valve Finish do I Require?

The great thing about radiator valves is that they are just as customisable in colour and finish as your radiator can be. There is nothing worse than having a lovely new radiator installed, only to have the installation look a little out of place, with valves (for lack of a better phrase) sticking out like a sore thumb.

A specific finish from your radiator valve can help to add some style, especially if you’re working with a unique radiator or a heated towel rail.
