Should all radiators have thermostatic valves?

You should have thermostatic radiator valves (TRVs) on all radiators but not in the same area as a wall thermostat, it is possible that this room may never get warm enough to turn the boiler off via the wall thermostat if the temperature in this area is being controlled independently by a TRV.

Should there be a thermostatic valve on every radiator?

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 radiators have to have TRV?

You can leave any radiator without a TRV, but it makes more sense for you to select the radiator in the room with your wall thermostat.

Are thermostatic valves necessary?

The short answer is yes. In theory, having thermostatic valves installed in every room can save you up to 40 percent on your energy consumption according to TheGreenAge.com. The thermostatic valve helps save money by allowing you to adjust the temperature on different radiators in the house.

Can you turn down a radiator without thermostatic valve?

While some radiators just have an on and off switch, a thermostatic radiator allows you to control the amount of heat it puts out. If your radiator doesn't have a thermostatic valve or is a 1-pipe system, you can skip this step.

All my radiators have thermostatic valves except one, why is that ? Can I put one on.

Do all radiators have a lockshield valve?

Lockshield Valves Explained

A lockshield valve is slightly different from manual and thermostatic valves as it controls how much water can exit a radiator. Every radiator has one, and you need them to make sure all the radiators remain balanced in your central heating system.

Are TRV valves a legal requirement?

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).

Is a thermostat a legal requirement?

All new heating installations must be fitted with a room thermostat to meet with building regulations. If your property is over 150 m2 it is recommended the system be split into zones and have thermostats for each zone ( i.e. upstairs zone 1, downstairs zone 2 ).

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.

Can you put thermostats on old radiators?

Thermostatic valves can be fitted on any radiator, except the room where the main thermostat is located.

Should a combi boiler have a thermostat?

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. Also, there should be some form of time control for the hot water.

Do I have to have TRVs with a new boiler?

“Although TRVs are not an entirely new solution for most installers, now is the time to ensure that they are not overlooked,” Martyn says. “Making them a legal requirement, not only validates best practice, but also ensures that TRVs are considered for all new and replacement boiler scenarios.”

Does a central heating system need a thermostat?

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.

Which side of a radiator does the thermostat go?

Most modern thermostatic radiator valves are bi-directional – so can be fitted on either the flow or return pipe of your radiator. However, it's always best practice to fit the TRV on the flow pipe that enters your radiator.

What is the TRV on a radiator?

Thermostatic Radiator Valves (TRV) explained

The thermostatic radiator valve (TRV) is used in office and apartment buildings to provide zoned heating from a central boiler. With a built-in temperature sensor, the TRV will automatically adjust the heat output from the radiator to help maintain a steady room temperature.

Do radiators have two valves?

The two radiator valves on a radiator work in the same way as taps, affording the user control over the level of heat they emit. One valve accounts for the amount of hot water that enters the radiator.

Where is the thermostatic radiator valve?

Thermostatic radiator valves are commonly referred to as TRVs and are used to control the air temperature of different rooms – you will normally find them on the side of your radiators. TRVs are just one of a number of heating controls, which allow homeowners to heat their homes more efficiently.

What is the difference between a lockshield and radiator valve?

The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room.

How do you balance upstairs and downstairs radiators?

Do all radiator valves fit all radiators?

In fact, some radiator valves just won't be compatible at all and others can't be used with certain radiators because of size, shape and design.

What does a TRV do?

The TRV is a valve that self-regulates, meaning it adjusts the flow of water into your radiator depending on the setting. The thermostatic valve head goes on top of the valve body. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes.

Is it cheaper to leave heating on low all day?

According to experts at the Energy Saving Trust, the idea it's cheaper to leave the heating on low all day is a myth. They're clear that having the heating on only when you need it is, in the long run, the best way to save energy, and therefore money.

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

For a modern combi boiler, the radiator heating temperature should be set at or around 75 degrees celsius for the best efficiency and performance.

What temperature should my boiler be set at in winter?

As a rule, setting your heating control to 75 degrees should be sufficient to give you a perfectly warm house, while also allowing your boiler to run as economically as possible. Once this is set, you shouldn't need to adjust it.
