This video covers thermostatic radiator valves. How they work and how you can install them. We also cover which room to install them and why.

Today, we’re gonna look at thermostatic radiator valves otherwise known as TRVs. They individually control the temperature in the room to an individual radiator. Firstly, we’re gonna have a look at how to change them, and then we’re gonna have a look at how they work. I hope it’s very informative. Hold tight. So, how does a thermostatic radiator valve work, and what’s the difference between that and a normal radiator valve. Well, firstly, a normal radiator valve is just a valve that moves up and down and shuts off the flow of hot water from the boiler into the radiator, just like the tap on a bathtub. The main difference with a thermostatic radiator valve is that it automatically controls the amount of hot water going into a radiator according to the current heat of the room that it’s situated in. There are two main types of thermostatic radiator valve. One uses a spring that expands and contracts, and the other uses a wax jacket that does exactly the same. For this video, we’re gonna look at the spring type, because they both work in a very similar way. So, we have a spring that is made of metal that is very susceptible to the temperature around it. If the room is cold, the metal will be contracted because when metal is cold, it is contracted. Therefore, the valve jumper will be open and hot water will be allowed to flow into the radiator. If the room is warm, the spring will expand and that valve will be pushed down and the flow to the radiator will stop. And that’s how they work. A very common problem I have with customers is, sometimes they’ll come in, the room is cold, the radiator, when they feel it, blazing hot, and yet they still go to the thermostatic radiator valve and open it up more. That’s completely pointless. The room is cold, the radiator’s hot, therefore, the thermostatic radiator valve knows that the room is cold, and it’s trying to heat it up. If you go into a cold room and feel the radiator and it’s hot, do not touch the thermostatic radiator valve. Only touch it when you go into the room, and it’s cold, and you find that the radiator is cold. Also, another thing you need to consider, is where you can actually install thermostatic radiator valves. If you have house with two rooms, in one room you have the room thermostat, which controls the whole heating system, and one radiator. In the other room, you have another radiator and that has a TRV on it. Don’t put a TRV in the room that has the room thermostat in it. The reason for that is, if the TRV closes down, and the room thermostat is not satisfied, it will never knock the heating system off to the whole house, and you won’t get any saving. That room thermostat there needs to have an exactly true reading of the maximum capacity that the heating system can give out. Therefore, the radiator in the room with the room thermostat should have a lock shield on it that is fully open. So let’s go back to the house, and find out how you actually change a lock shield over for a TRV and really how easy they are to install. I’m assuming you all know how to drain down a heating system already. Finding the lowest point in the heating system and drain off, taking your hose outside and opening that up and making sure that the water supply is turned off to the heating system. Next, you allow air into all the radiators that you want to change in the TRVs. Generally, if you’re a bit worried about this, let air into every radiator in the house. You should hear the air sucking. As soon as you see your hose outside stop running, that should indicate that the heating system is drained down and you’re ready to change the valve. Let’s have a look here. As you can see, we’re removing this old lockshield valve here, which is just an on and off valve. So, now that we know the system is all drained down, we can loosen that off. Now’s the time just to make sure that the water has drained out of the system. As you can see it has. And then we can loosen off the 15mm pressure fitting on the bottom. As you can see, our new TRV isn’t going to fit on this current radiator insert. All new TRVs are supplied with a new insert, so this one here will need removing. There are special tools to do this. You can have a hexagonal tool that goes in like that, a square tool, a lug tool cut in here. This is quite an old one as you can see. Today I’m gonna use this one here because we’ve got hexagonal fitting on there. Now often you can just lift out and it may get out. But generally, you’ll have to just put the spanner on like this and then wind it out like that. There’s the old insert out, and that’s the old valve completely removed.

If your vehicle is equipped with automatic climate controls, this is your control panel. It is made up of two multifunction controls and several buttons. The two outer controls consist of a center button and an outer ring that works like a dial. If your vehicle is equipped with a different climate control system, see your Owner’s Manual for additional information.

The Auto mode may be used all year round. To turn it ON, press this button for automatic cooling or dehumidified heating. The indicator light illuminates when the system is activated. It will automatically regulate and maintain fan speed, airflow and temperature in the cabin. The Auto mode can be turned OFF by changing the fan speed, or by pressing the DEFROST or MODE button.

Your vehicle has separate temperature controls for the driver and front seat passenger. The driver’s TEMPERATURE CONTROL dial, on the left, will set the temperature for both the driver and passenger if the DUAL button is not activated. Turn the outside ring of the driver’s side control. You’ll see the temperature setting change on the center display as you turn the ring left for cooler, or right for warmer air.

If you want to adjust the passenger side temperature independently from the driver’s side, press the DUAL button, or turn the passenger side TEMPERATURE CONTROL dial. The DUAL indicator light will illuminate. Turn the dial left for cooler, or right for warmer air. The passenger’s side temperature will be displayed. To switch back to driver control, press the DUAL button again. If in Dual mode when you turn your system OFF, using the OFF button, it will resume Dual operation when turned back ON using the AUTO button.

The MODE button provides a choice of airflow outlets. Press the MODE button repeatedly to select from the following:
● Air will flow from center and side vents,
● Air will flow from center and side vents, and foot outlets,
● Air will flow mainly from foot outlets,
● Air will flow from the defroster and foot outlets, or
● Air will flow from the defroster outlets.

Press the A/C button to turn the air conditioning ON or OFF.

In hot or humid conditions, a visible mist may be seen coming from the vents. This does not indicate a malfunction.

To defrost or defog front and side windows, press the FRONT WINDOW DEFROST button. The indicator light will illuminate. airflow will be directed to the front and side windows. The A/C automatically activates when the Defrost mode is selected and the outside temperature is above 36 degrees. This helps dehumidify the cabin and clear the windshield faster. Turn the driver’s side temperature to a setting that will best meet weather conditions. For windshield deicing, the temperature selector should be turned to maximum heat. Also, using the manual fan control, turn the fan speed to high.

If your vehicle happens to be in Dual mode, turning ON the defroster will automatically revert to driver control, allowing both sides of the windshield to defrost evenly. After the windshield is cleared, press the AUTO button to return to your previous settings.

To defrost or defog the rear window and, if so equipped, the outside mirrors, press the REAR WINDOW DEFROST button. The indicator light will illuminate. After defrosting, press to turn OFF. If not turned OFF manually, this feature will automatically deactivate in a period of time.

To recirculate air inside your vehicle, press this AIR RECIRCULATION button, its indicator will light up. This helps A/C efficiency and helps block outside odors from entering the cabin. You will only be able to activate the air recirculation feature when non-defroster airflow settings are selected. Press the FRESH AIR INTAKE button to allow outside air to be drawn into your vehicle. Please be aware that while in defrost modes, the air recirculation feature will not activate. Allowing outside air to enter the vehicle further improves defogging performance.

Press the fan control buttons to manually control fan speed. To turn the system OFF, press the OFF button.

There is a temperature sensor located on top of the dashboard, near the windshield, that helps regulate the automatic climate control settings. Please keep this area clear of papers and other materials.

Please see your Owner’s Manual for important safety information, system limitations and additional operating information.
