Everything You Need to Know About TRVs

Published: 16 Feb 2024 ・ Read time: 6 mins
Thermostatic radiator valves (TRVs) are small but crucial components in modern heating systems. With ongoing temperamental weather in the UK especially, TRVs help homeowners get the balance right indoors no matter what the temperature is outside. This not only creates a comfortable living environment but ultimately reduces energy bills.
Yet, many people are unfamiliar with TRVs and how they work. So here at City Plumbing, we’ve created a quick guide on what you need to know about thermostatic radiator valves, including their benefits, installation, and maintenance. 
Whether you’re a homeowner, a heating engineer, or simply interested in learning more about the best heating systems, we’ll help you make the best choice.

What Do TRVs Do? How Can They Help Control Heating Costs?

Thermostatic radiator valves allow users to control the temperature of individual radiators in a central heating system, providing greater comfort and energy efficiency. This means TRVs enable more control over energy consumption when heating different rooms in your home according to requirements, rather than heating the entire house to the same temperature.
The ability to control heating on a room-by-room basis can lead to significant energy savings, as you only need to heat occupied rooms, rather than maintaining a consistent temperature throughout the home. This result is lower energy bills and a more efficient heating system overall.
It's important to note that TRVs should be used in conjunction with a main thermostat, which controls the overall temperature of the heating system. This ensures that the heating system works in harmony, providing comfort and energy efficiency when working to achieve that ideal home temperature.

Compatibility: Check if the TRV is compatible with your existing heating system. Some thermostatic radiator valves are designed to work with specific types of radiators and boilers, so it's important to ensure compatibility before buying.
Accuracy: Look for TRVs that offer a high level of temperature accuracy. This ensures that the desired temperature is maintained consistently, preventing overheating or unnecessary energy consumption.
Energy-saving features: Consider TRVs that have energy-saving features such as open window detection or adaptive start. These features can help reduce energy wastage and lower your heating bills.
Ease of use and installation: Choose TRVs that are easy to install and operate. Look for models with clear, user-friendly instructions and intuitive controls.
By taking these factors into account, you can select a thermostatic radiator valve that suits your specific needs and enhances the efficiency of your heating system.
