Everything You Need to Know About Thermostatic Radiator Valves

Radiators are made up of a whole host of different parts. With beautiful aluminium frames and a diverse selection of top radiators for bathrooms and kitchen radiators on the market, it can be difficult to decipher what each part does in the central heating system. From the bleed key to the corner valve, each part of a radiator plays a specific function which not only acts as a single cog in the larger whole but is unique in design too. One such element is the thermostatic radiator valve, one of the most important parts of the radiator. We’ve compiled everything you need to know about the thermostatic radiator valve, and given a brief guide on why it’s so important.

 

What Is a Thermostatic Radiator Valve?

Thermostatic radiator valves are self-regulating components within a radiator system. These radiator valves are fitted with a wax “motor” which expands and contracts when it comes into contact with air. The wax motor located inside the valve is set to a specific temperature and by way of shrinking and enlarging,  it ensures the central heating system is never hotter than you want it to be.

 

How Do I Use My Thermostatic Radiator Valve?

The thermostatic radiator valve is located on the bottom corner of your radiator. It is usually a metal head with a sliding scale of numbers. The great thing about a thermostatic radiator valve is that you don’t have to do much to get it working, it being self-regulating and all. Simply set the temperature you would like the room to remain at, and your thermostatic radiator valve will regulate the heat emanating from your radiator.

 

Why Use a TRV?

How important is a thermostatic radiator valve? Is it a vital component in the radiator set up, or is it just a mere add on?

 

Cost Efficient

One key aspect of the thermostatic radiator valve is that it is incredibly cost-efficient. Once you’ve set your room temperature, the valve will maintain that heat until the heating is turned off. This means that there is never any excess warmth in your home and therefore saves on your heating bills.

 

Energy Efficient

Energy efficiency goes hand in hand with cost efficiency. One vital aspect of modern life which is currently in the cross-hairs is our individual carbon footprint. The more efficient we are in our energy usage, the lower our carbon output will be. Every little tweak really will help, but remember that the power is in your hands; you’re the one who will have to set an efficient limit to your radiators heat output.

 

What Are the Numbers on a Thermostatic Radiator Valve?

The thermostatic radiator valve has a sliding scale of numbers between 0 and 5 at its head, separated by increments of dashes or dots. This scale is commonly referred to as the Danfoss Head and these numbers represent not the heat of the radiator, but the maximum room temperature the radiator will work towards. With 5 representing between 24 and 28 degrees, the number 4 is between 21 and 24. This continues all the way down to 1, which represents 12 degrees.

 

Each number on the Danfoss Head has a recommended room for its designated temperature. With a cool 1 being best for laundry rooms and cellars, 2 is best for the entrance hall of your home. Higher 2’s and low 3’s are great for bedrooms whilst high 3’s and low 4’s are the perfect temperature for the living room or bathroom.
