Do Combi Boilers Need Thermostatic Radiator Valves?

If it is a ‘combi’ boiler and provides instantaneous hot water then no additional controls are needed. If you have a separate hot water cylinder then there should be a thermostat on the cylinder to turn the boiler off when the water is hot enough.

Should all my radiators have thermostatic valves?

We recommend you fit a thermostatic valve on every radiator. But there’s no need to fit one in a room with a fixed room thermostat.

Do you have to fit TRVs with a new boiler?

The revision requires individual room temperature controls, such as TRVs, to be installed either during the construction of new buildings, or when boilers are replaced. Martyn says: “TRVs are highly effective at improving heating efficiency and comfort in the home.

Do you need a thermostat with a combi boiler?

Do you need a thermostat for your boiler? In short: yes. Your boiler thermostat is essential if you want to be able to control the temperature of your central heating and hot water.It’s called the Boiler Plus legislation, and applies to all gas and oil boiler installations.

Are TRV mandatory?

Building Regulations state that all new and modified wet central heating systems must have a TRV fitted to every radiator (apart from one where the room thermostat or programmable thermostat is installed, typically in the hall).

Can you turn down a radiator without thermostatic valve?

Non-thermostatic valves
Step 1: Also known as a manual valve, find the non-thermostatic valve on the left or right side at the bottom of your radiator. The other valve on the radiator will be fixed or will be capped. Step 2: To turn your radiator off, turn the valve clockwise as far as it will go. Top Tip!

Do radiator valves fit all radiators?

While most radiators will see valves meet the pipework at a 90° vertical angle, corner radiator valves are made for use on a horizontal plane, i.e. when pipes come out from the wall and not the floor. You mustn’t accidentally buy corner valves for a traditional radiator installation as they can’t be adapted.

Can I install a combi boiler myself?

Is it possible to install a combi boiler by yourself? To follow building and safety regulations, new gas boilers need to be installed by an installer with a Gas Safe certificate.The Gas Safe Register means your gas engineer is able to work safely and legally on your boiler.

Why do you have to a one radiator without a thermostat?

The thermostat controls the boiler and turns the boiler off when the air temperature (yes recorded in one place usually the hall or lounge). The radiator valves do not control the boiler and at least one radiator should be on all the time (have no control).

Do you need a thermostat for central heating?

In a central heating system, the main thermostat is an essential component. Without it you would have to turn your heating on and off multiple times a day to try to keep the temperature in the home reasonably constant.

What temperature should my combi boiler be set at for central heating?

Adjust the boiler controls
Combi boilers have controls on the unit which allow you to set the temperature of the water that will be circulating around the central heating system and out of the taps. The best setting for combi boilers is often recommended as 75°C for central heating and 60°C for domestic hot water.

Can I use any wireless thermostat with my boiler?

Can you connect a wireless thermostat to any boiler? The particular wireless thermostat you have will affect whether it can be connected to your boiler. In most cases, they are compatible with most modern boilers, including combi, system and heat-only boilers.

What temperature should a combi be set at?

Modern boilers will have a digital dial where you can set the output temperature. For combi boilers it is recommended to set the output temperature for the radiators at 75 degrees and the water temperature at 60 degrees.

Are TRV valves a legal requirement?

“TRVs are far more sophisticated, creating heating zones and supplying a controlled level of heating to suit individual rooms.“By making it a legal requirement, this not only validates best practice, but also ensures that TRVs are considered for all new and replacement boiler scenarios.”

Do new radiators come with valves?

Radiators don’t come with valves because it’s better for you that they don’t. You not only need to choose which radiator valves you want because your pipework isn’t the same as everyone elses, but neither is your taste in interior decoration.

Which side of radiator does thermostatic valve go?

However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator. If a non-bi-directional thermostatic valve is fitted to the return side of the radiator, it can make a loud vibrating noise when water tries to pass through it.

What is the quickest way to balance your radiators?

How To Balance Radiators

1. Turn off your heating.
2. Open all radiator valves.
3. Note the speed each radiator heats up.
4. Allow your heating to cool down.
5. Turn your heating back on.
6. Adjust the fastest radiator.
7. Repeat for other radiators.

Why are my radiators still hot when heating is off?

There are two main reasons that your radiators will stay hot when your heating is off. It normally comes down to a problem with either your diverter valve or your check valve.They’ll run some tests and establish whether it is indeed a check valve or diverter valve at fault – or a different underlying issue altogether.

Do you bleed a radiator when it is on or off?

Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.

Are thermostatic radiator valves universal?

However this in not the case now and most, if not all, TRVs are universal, meaning that the flow can be either way through them without making and alterations to them. This means that there is no restriction to which side of the radiator they can go.

Are all radiator valves universal?

The connection between your valve and the radiator is standard across all moderns radiators and valves. The size differences listed above refers to the width of your pipes that the valves will slot onto. Most of the time it’s 15mm, but measuring your pipes will confirm.
