Thermostatic radiator valves (TRVs) can save a lot of energy and money. They regulate hot water flow to a radiator to maintain a comfortable room temperature while minimizing energy consumption.

TRVs measure the temperature of the air around the radiator. When the air temperature falls below the set point, the valve opens to allow more hot water to flow into the radiator.

If the air temperature is higher than the set point, the valve closes to reduce the flow of hot water. Therefore, TRVs can help to keep a room at a consistent temperature without wasting energy.

Using TRVs can also help to extend the life of your boiler or heating system by preventing it from working overtime to heat your home.

An estimate is that TRVs can save you approximately 40% on your heating expenses. Due to this, investing in TRVs is a great way to save energy and money. TRVs also act as manual valves because you can still adjust the flow of hot water manually.

An investment in a quality TRV is much more important since a low-quality TRV may not perform as expected. That is why you should check out the top-rated smart thermostatic radiator valves before purchasing.

    In this way, you will be able to ensure that you obtain the most suitable product for your needs. The following are some of the most important factors you should consider.

    1. Material

    During the passage of hot water through the radiator valve, temperatures can reach high levels. Because of this, the valve material should be one that can withstand high temperatures without succumbing to deterioration.

    Water also causes rust and corrosion, so choose a valve made of corrosion-resistant material. Brass is one of the most popular materials for thermostatic valves because it is durable and corrosion-resistant. 

    Copper and bronze are also good choices. ABS plastic is a good choice for outer coverings since it is also corrosion-resistant and durable. There are a few different places you can look to find out what materials went into making TRV valves.

    One option is to check the manufacturer’s website. Many companies provide detailed information about the materials they use in their products. 

    One of the easiest and most convenient ways to determine the materials used is to refer to the product description. You may also find this information on the packaging of the product.

    2. Connection Type

    When selecting a thermostatic radiator valve, it is essential to consider the type of connection. You should choose a valve that matches your radiator’s pipe connections and threading. This will ensure a tight seal and prevent any leaks.

    Before purchasing a valve, you should know the radiator’s connection and threading size. Most manufacturers provide this information on their websites or in their product manuals. Once you know the size of the connections and threads, you can narrow down your choices and select the most suitable valve for your needs.

    3. Temperature Adjustment Range

    angled valves

    The numbers and temperatures of thermostatic radiator smart valves indicate the temperature to which the radiator will be set. The most common settings are 0, 1, 2, 3, 4, and 5. Setting the TRV to 0 will turn the smart thermostat radiator off, while setting it to 5 will set the temperature to 30°C.

    In between these two extremes, each number corresponds to an increase of 5°C. For example, setting the TRV to 2 will set the temperature to 15°C. It is important to note that the exact temperatures may vary depending on the brand of TRV.

    Generally, higher numbers correspond to higher temperatures. Frost-proofing features are present in high-quality TRVs, which help prevent radiators from freezing and cracking.

    You’ll usually see this in the “*” symbol. When you are going to be away from home for an extended period of time, you can set it to this position.

    So, when choosing a thermostatic radiator valve, make sure to check the temperature adjustment range and select one that meets your needs. You can find the information in the product description or on the packaging.

    4. Maximum Working Pressure

    You also need to consider the maximum working pressure of the valve. The maximum working pressure refers to the amount of water pressure that the valve can handle. 

    In general, thermostatic valves do not require a high water flow rate. But it is beneficial to have a valve that can handle a higher flow rate in case the water pressure in your home suddenly increases.

    A valve with a pressure rating of 10 bar or less is sufficient. Check the product description or packaging to find the valve’s maximum working pressure.

    5. Accuracy

    Another important consideration is accuracy. The accuracy of a thermostatic radiator valve (TRV) indicates how well it can maintain the set temperature. To identify how accurate the thermostatic radiator valve is, you will need to look for the accuracy rating.

    If you cannot locate the accuracy rating, you should read reviews of the product to determine its accuracy. Experienced users will be able to tell you how well the TRV maintains the set temperature.

    Can Thermostatic Radiator Valves Be Repaired?

    smart home

    Yes, you can repair a thermostatic radiator valve (TRV) if it is not working properly. But not all TRV problems are repairable.

    If your TRV has become stuck in the open or closed position, you may be able to repair it. To do this, you will need to disassemble the valve head. To loosen the screw on the head, turn the screw clockwise. Once the screw is loose, you can remove the head.

    You will find a pin attached to the stem inside the head. This pin is what controls the opening and closing of the valve. If the pin is stuck, you can apply some lubricant to it. This will help loosen it up. Once the pin moves freely, you can reassemble the valve head and screw it back into place.

    If you have a TRV that is leaking, there are a few things you can do to repair it. You can check the O-ring. The O-ring is a small rubber ring that helps to seal the connection between the valve and the pipe.

    Whenever it becomes broken or worn, a replacement is necessary. Next, check the valve itself. If it is loose, tighten it with a wrench. If the valve is still leaking, you can add PTFE tape to the threads. This will facilitate the creation of a better seal.

    But if your TRV is not responding to the thermostat or the valve is deteriorated beyond repair, you will need to replace it.

    How Long Do Thermostatic Radiator Valves Last?

    How Long Do Thermostatic Radiator Valves Last

    Typically, thermostatic radiator valves last for many years. They can last for decades if taken care of and maintained properly. But the lifespan of a TRV will depend on the quality of the product. Cheaper TRVs might only last for a few years, while more expensive ones could last for decades.

    The life expectancy of a TRV will also depend on its usage frequency. If you use your TRV frequently, it will not last as long as it is used infrequently. Also, in areas with hard water, the TRV may have a shorter lifespan than it would in an area with soft water.

    To extend the lifespan of your TRV, you should follow the manufacturer’s instructions for care and maintenance. You should also regularly check the valve for leaks and damage. If you notice any damage, you should replace the valve immediately.

    How Often Should You Check Thermostatic Radiator Valves?

    How Often Should You Check Thermostatic Radiator Valves

    You should check your thermostatic radiator valves at least once a year. This will help you to identify any problems early on so that you can take care of them before they become more significant issues.

    During your yearly check, you should look for any deterioration in the valves. You should also check for leaks and ensure the valves are still working properly. If you notice any problems, you should take care of them immediately.

    It is also important to confirm that the TRV sensor is still functioning. For this purpose, you can detach the TRV and install it in a gallon.

    Installing the TRV in a gallon requires setting up the pipe threading on the gallon. After that, you can install the TRV. Fill the gallon with water and turn the TRV on.

    Make sure you place a second container under the gallon to collect any water that may spill. After turning it on, place a portable heater near the TRV, and set the temperature accordingly.

    In the case of a properly functioning TRV, the valve will close when the temperature reaches around 30 degrees Celsius.

    Generally, if the valve responds well to the temperature, it indicates that the sensor is functioning correctly, and there is no need to replace the device. If not, then you need to take out the device and put it in a new one.
