Thermostatic Radiator Valves (TRVs) regulate the flow of water into the radiator depending on the setting to control the room temperature. It uses wax or liquid sensors which expand and contract to adjust the pin into the valve. The type of material used can largely impact the efficiency and accuracy of the mechanism.
Earlier, the performance and efficiency of TRV are determined by its response time. And undeniably, the liquid was considered to be more responsive among the two. Crucial variables include response time, high temperature, hysteresis, pressure, and accuracy. Once all these factors have been taken into account, you can get thermostatic radiator valves in Ireland or elsewhere that never fail to impress in terms of performance.
Importance of Thermostatic Radiator Valve (TRV)
TRV is one of the heating controls that is used to regulate the temperature within a central heating system. When fitted and used correctly, it enables users to regulate the heat on each radiator, giving great flexibility, reducing heat on rooms, and maximizing system efficiencies.
To that end, the major question commonly faced in the industry is two forms of TRVs available – liquid and wax and particularly, the difference in performance that element makes.
Which Element?
Both wax and liquid TRVs are used widely for many years and the decision between the two usually comes down to users’ preferences and needs. The critical operating essentials of TRVs is that it self regulates and adjust the flow of water into the radiator depending on the setting. As the room temperature fluctuates, the element in the valve heat expands, allowing the valve to open and close, and this is where the wax or liquid content is produced.
Both offer automatic adjustment, helps regulate temperature, save fuel and money. While the liquid is a recent development and offers significant benefits, wax proves to be popular among installers who want to maximize efficiency and fit A-rated products for consumers.
What’s the Difference Between Wax and Liquid TRVs?
Wax components are smaller than liquid, providing design freedom and superior surface area to volume ratio. It has a thermal conductive copper flake in suspension, whereas liquid is a clear liquid. Additionally, the force, an element that drives the pin, spring, and valve seat generated by wax are greater than liquid. It helps to avoid valve sticking.
Increased safety standards are linked with liquid being flammable and solvent, whereas wax is a mineral and contains anti-flammable properties as a crucial consideration for homes.
Benefits of Wax TRVs
- Compact sensor element
- Safer and quicker
- Reliable
- Long-lasting
- Prevent valve sticking
Benefits of Liquid TRVs
- Detect changes in temperature faster
- A recent alternative
What Should You Choose?
It would be fair to say that every installer has its favorites and narrow down choices in terms of performance and satisfaction rate. Yet, a change is necessary, especially if your main focus is energy efficiency. Keeping a scientific aspect in mind, liquid models have the advantage of faster response time as compared to the wax-filled sensor. As wax is a slightly heavier, denser material, it is slow to expand or contract.
Conclusion:
For new-build properties, energy-saving is a big requirement to allow heating systems to meet the maximum standard of controllability. For existing properties, the installation of TRVs is encouraged to obtain a good sense of temperature control.
Clearly, the TRV market continues to evolve with passing time and new products emerge such as wax or liquid TRVs. Hence, the choice depends on key variables, user preferences, needs, and budget. If you’re looking for tall radiators, make sure to install TRVs as a viable specification of the heating system.
