Thread new steam valve into radiator; tighten with adjustable wrench. Apply Teflon tape to threads of old air vent. Thread old air vent into top of new steam valve.

What are the parts of a thermostatic radiator valve?

A TRV is made up of the two parts; the thermostatic valve head (with the dial) and the valve body underneath, which fixes onto the pipe coming from the boiler and going into the radiator. How do thermostatic radiator valves work? Depending on how you set the valve, it adjusts the flow of water that goes into your radiator from the boiler.

Do I need a thermostatic radiator valve on every radiator?

Standard practice is to leave one radiator without a thermostatic radiator valve installed, and to leave that appliance permanently switched on. If your boiler is fitted with a flow meter – that detects when all of your radiator valves are closed, you can install a TRV on every radiator if you want to.

How do I remove the pin from the thermostatic radiator?

You can still pull the pin out with mole grips, but at least the pin will stay in the mole grips so you can quickly pop it back in. First of all, remove the heat control off of the top of the Thermostatic Radiator Valve, on most models you have to rotate the screw top under the control head to achieve this

Can you change TRV without draining system?

However, if you are only updating one radiator you can change the radiator valve without fully draining the system and there are actually benefits of doing so. For example, the water in your central heating system is filled with heating additives and inhibitor which protect the system.

Is it worth getting thermostatic radiator valves?

Yes! Thermostatic valves are the best way of getting the heating in your home just right! Used in combination with a room thermostat, they adjust your heating perfectly, and you won't end up with some rooms being overheated.

How do you fix a leaking thermostatic radiator valve?

Leaky thermostatic radiator valve You can seal a leaky TRV with some plumbers' tape (plumbers call it PTFE tape). First, isolate the radiator by turning both the TRV and the lockshield valve on the other side to 'off' or closed. The two compression nuts are strong suspects for the leak.

Does it matter which way a radiator is plumbed?

If the arrow points away from the valve it needs to go on the return side of the radiator, if it points into the valve it should be on the flow side.

What are the two valves on a radiator for?

Each radiator will have two valves. One will control the amount of hot water that enters the radiator and the other will balance the system by controlling how much heat comes out of your radiator. This is known as the 'lockshield valve'.

Are radiator valves handed?

To close a radiator valve, you need to turn it clockwise as far as it will turn. Some radiator valves can be turned with your hand, but for some, you will need to use a tool to open the valve, like some pliers or an adjustable spanner. To close a thermostatic radiator valve, you turn it clockwise until it's on zero.

What is the head of a thermostatic radiator valve?

The head of the thermostatic radiator valve senses the temperature that it is in the room. The radiator pushes the steam through the supply pipe into the valve. When the temperature of the room and the air is the same, it doesn’t vent to prevent the room from over heating.

Can you use a thermostatic steam radiator valve?

Using a one-pipe thermostatic steam radiator valve, you can regulate the temperature and make every single radiator it’s own zone. For safety reasons, before you follow the steps below and in the video, make sure your thermostat is turned off.

How Much Does A Thermostatic Radiator Valve Cost?

A standard pair of TRVs will set you back about £20, whether you buy them from our store or decide to shop for them somewhere else.

Why does my radiator valve keep sticking?

The most common and regularly occurring problem with a thermostatic radiator valve is that the valve – or the head of the valve – begins to stick or catch. This will leave them open or closed and can happen when the setting on the valve has not been adjusted for some time – such as at the end of a long hot summer.

How Does A TRV Work?

A Thermostatic Radiator Valve is self-regulating and works by automatically changing the flow of hot water that comes into your radiator at any one time.

What Do The Numbers On A TRV Mean?

Contrary to popular belief, the numbers on your TRV do not represent specific room temperatures, because as I have mentioned, the temperature at which the valve operates depends on water temperature, the airflow around the valve, the size of the room and the heat loss in that space through walls, windows and floors.

Why does my radiator cover stop my TRV?

As in the image above, this radiator cover is arguably stopping the TRV from operating at its best, as it is blocking any draught or airflow to the valve, this could lead to the valve not operating correctly and the space not heating up as well as you may like.

Why does my TRV think my room is colder than it is?

It can sometimes be the case that a draught is causing the TRV to think that your room is colder than it actually is – this is particularly common if you have a door near to your radiator.

What happens if you have two radiators in a room?

If you have a room that is heated by two separate radiators, there will be an interaction between two TRVs, competing to be in charge of how hot or how cool the room is.

Can LS valve be on the flow?

doitmyself said: The LS valve can be on the flow or return; all it is doing is setting the max flow through the rad. What goes in is the same as what comes out, so which side the LS valve is doesn't matter.

Can a TRV be placed on either end?

But non-bi TRVs can be put on either end provided the arrow on TRV points in the direction of flow. On one end the head will be vertical; on the other end it will be horizontal.

Can a rad valve be a return valve?

not with modern rad valves as normally they are bi-directional so can fit on flow or return, but check first

Why isn't my radiator hot?

There are various reasons why a single radiator’s not getting hot, and the most common cause is the pin in your Thermostatic radiator valves stuck. Thermostatic Radiator Valves are wonderful inventions allowing the perfect heat setting for each room. The valves incorporate a pin that opens and closes regulating the flow ...

Why is my radiator pin stuck?

When the pin gets jammed in the closed position, it will let little to no hot water into your radiator. The pin does get sometimes stuck it’s very common when the heating hasn’t been turned on for a few months.

What is a one pipe steam radiator?

Adjusting the size of the opening into a one-pipe steam radiator causes problems with condensate drainage so instead, we control the air that leaves it.

How does the thermostatic head work?

Turning the handle of the thermostatic head adjusts the distance that the actuator must expand by to close the valve. Many TRVs have a 1 to 5 scale - with 1 representing the smallest distance and 5 the greatest. The larger the distance, the warmer the room must be before the valve is closed.

What happens if you don't get air out of a radiator?

Before a heating cycle starts one-pipe radiators are full of air. If that air can't get out, the steam can't get in. Adding a thermostatic valve between the radiator and the air vent adds control to the amount of air that can escape and, as a result, the amount of steam that enters the radiator.

Why do you need to shut off the thermostat?

If you need to shut the valve off completely, when removing the radiators from the system in order to decorate, for instance, use the decorator’s cap supplied with the valves.

What is a valve body?

The valve body has a sprung plunger inside it that closes and opens the supply of water (or steam, in two-pipe installations) into the radiator. Above - thermostatic head (left) and valve body (right). When the two are put together the supply of heat into the radiator is automatically controlled with respect to the temperature of the room.

When do radiators stop heating?

When the two are put together the supply of heat into the radiator is automatically controlled with respect to the temperature of the room. When the room reaches the desired temperature, the valve closes and the radiator stops heating. The room then cools, the valve opens and the radiator begins to heat again.

Do thermostats work independently?

We recommend a learning thermostat such as Nest . Thermostatic radiator valves work completely independently to the boiler and don't have any direct control on its operation. There is an indirect link - TRVs control the temperature of each room, and therefore have an effect on the temperature that's sensed by the wall thermostat.

How to set temperature on thermostat?

Place the head on top of the valve, tighten the clamp and turn to set the temperature. Thermostatic valves can be fitted on any radiator, except the room where the main thermostat is located.

How to isolate a radiator?

How to make a loft space airtight?

Isolate the water at the primary system and turn it off at the electricity supply. Then block the vent and feed on the expansion tank in the loft space. You can do this by putting a rubber bung in the 15 mm feed. The system is now airtight and under atmospheric pressure.

Can you use Allen key on radiator valve?

You can’t use a radiator Allen key on the new valve as it is a 15mm pipe size. Use an adjustable spanner to tighten, keeping the valve straight. Step 6. Re-fit the radiator. As it’s a standard 15mm compression joint, you can use the olive and nut from the old valve. So you can simply fit the radiator back into place.

What is the head of a thermostatic radiator valve?

The head of the thermostatic radiator valve senses the temperature that it is in the room. The radiator pushes the steam through the supply pipe into the valve. When the temperature of the room and the air is the same, it doesn’t vent to prevent the room from over heating.
