Understanding Thermostatic Radiator Valves

The ever-growing focus on energy efficiency and sustainability, has meant that optimising heating systems is now paramount. At Padly, we understand this and therefore, make it our priority to advise and guide homeowners on ways to make their homes as energy efficient as possible. A significant component in this regard is the Thermostatic Radiator Valve (TRV). However, we appreciate that Thermostatic Radiator Valves are one of the more difficult heating related devices to understand.

In this blog, our experts cover the ins and outs of TRVs to provide you with everything you need to know so that you can make informed decisions about your home's heating system.

What are Thermostatic Radiator Valves (TRVs)?

Thermostatic Radiator Valves are devices installed on individual radiators within a heating system, to regulate the flow of hot water into the radiator. Unlike traditional manual valves, TRVs are equipped with a thermostatic head that senses the ambient temperature of the room and adjusts the flow of hot water accordingly. This means that each room can be heated to its desired temperature independently, offering greater comfort and efficiency.

Understanding Building Regulations

Changes in Building Regulations for England emphasised the importance of TRVs and energy efficiency in heating systems. In 2022, it was mandated that whenever a boiler is upgraded, every room in the house must be equipped with either a thermostat or TRVs. This regulation applies to both new homes and existing homes undergoing boiler replacements. Compliance with these regulations is strongly advised not only for energy efficiency but also for overall comfort and cost savings.

How do TRVs work?

The operation of TRVs is relatively straightforward yet highly effective. When the temperature of a room reaches the desired setpoint, the thermostatic head of the TRV expands, causing the valve to close partially or completely. This restricts the flow of hot water into the radiator, preventing overheating of the room. Conversely, when the temperature drops below the setpoint, the thermostatic head contracts, allowing more hot water to enter the radiator and raise the temperature.

Benefits of TRVs

Energy and cost savings

By individually controlling the heating in each room, TRVs prevent unnecessary energy consumption therefore resulting in lower utility bills. Studies have shown potential energy savings of over 40% when TRVs are used effectively, making them a cost-effective investment in the long run.

Reduced carbon emissions

With TRVs, you can optimise your heating system so that it operates more efficiently which in turn, reduces overall energy consumption and carbon emissions. This contributes to environmental sustainability by minimising your household carbon footprint.

Enhanced comfort and flexibility

TRVs offer unparalleled flexibility in heating control, by allowing you to tailor room temperatures according to your preferences. Whether its keeping the living room cosy in the winter evenings or maintaining a cooler temperature in the bedroom for a restful sleep, TRVs can provide customisable comfort throughout your home.

So, do I need TRVs? 

If you are planning on replacing your boiler, our experts strongly advise that you also consider investing in TRVs. Not only will you be complying with current Building Regulations, but you will also receive their tangible benefits.

At Padly, we offer TRVs as an optional extra that you can add to your basket alongside your new boiler at checkout. Get a personalised quote online today!
