The most common problem with a TRV is that the valve sticks or catches. This means that they are either stuck open or closed.If you cannot get the plunger working again, then the valve has failed and will need to be replaced completely.
Why do thermostatic radiator valves fail?
Believe it or not, the most common cause for a thermostatic radiator valve to not be working correctly is because it has been set to the wrong number or turned off entirely.
Can radiator valves be faulty?
Whether the radiator valve is leaking or stuck in the same position, a faulty radiator valve can cause problems with your whole heating system. So replacing it is a must.
How do I reset my TRV valve?
If your Radiator Valve (TRV) is online in the Hive app you can factory reset it by selecting Remove from its Settings menu.
How do I know if my radiator thermostat is working?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Do thermostatic radiator valves go on flow or return?
Most modern thermostatic radiator valves are bi-directional so can be fitted on either the flow or return pipe of your radiator. However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator.
Should all radiators have thermostatic valves?
We recommend you fit a thermostatic valve on every radiator. But there’s no need to fit one in a room with a fixed room thermostat.
Why is one of my radiators not working?
If just one (or a few) of your radiators aren’t heating up, the most common reason for this is trapped air. If you’ve just turned the heating back on after the summer, air can become trapped in your radiators, causing them to be warm at the bottom but cold at the top.Your radiator should soon be nice and warm.
Can you use WD40 on radiator valves?
If it’s stuck inside the valve or stiff, a spray of WD40 will probably fix it. You can also try using a pair of long-nosed pliers to pull it out further. If it’s stuck right inside, try giving the valve a gentle tap around the outside edges, around the pin, with a hammer.
How long does a hive radiator valve take to pair?
During this learning phase the radiator valve opens the valve very slowly in order to detect the optimum opening point. This means it can take up to two hours for your radiator to warm up. The app and radiator valve will both show the temperature you have selected, but the radiator may stay cold.
Why is one radiator cold and hot?
If you are having a problem with just one radiator being cold, and you are getting heat out of other radiators in the system, the best starting point to fix the problem, is to start with the specific radiator itself.If the radiator is cold at the top, then the issue is likely air trapped in the radiator itself.
Why is my hive radiator valve not working?
If your Radiator Valve is still showing offline in the app, temporarily take it off the radiator following the steps in the User Guide and take it close to your hub. Then take out one battery from your Radiator Valve and put it in again. Your Radiator Valve will restart. Wait 5 minutes and then refresh the app.

- #3 Coolant Leaking.
- #4 Rumbling Noises.
- #5 Heater Malfunction.
How do you know if thermostat is bad?
7 Signs You Need to Replace Your Thermostat
- Your HVAC Keeps Turning On or Off.
- Faulty Thermostat Readings.
- Suspiciously High Energy Bills.

What are the signs of a bad car thermostat?
Symptoms of a Bad or Failing Thermostat

What is the quickest way to balance your radiators?
How To Balance Radiators
- Turn off your heating.
- Open all radiator valves.
- Note the speed each radiator heats up.
- Allow your heating to cool down.
- Turn your heating back on.
- Adjust the fastest radiator.
- Repeat for other radiators.
What do arrows on TRV mean?
Until about 1995 all thermostatic radiator valves were uni-directional. They were made with a single-headed arrow which marked the direction of flow. They had to be fitted so that the water passing through them followed the direction of the arrow. This meant that they were normally fitted to the flow pipe.
Should lockshield valve be fully open?
Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).
Do radiators leak when they need bleeding?
It’s helpful to bear in mind too that, usually, radiator leaks come from either the unit’s body, a bleed point, a valve or a pipe that pumps water into the radiator. Bleed valves are very common sources for leaks and relatively easy to put right.
Why is my radiator valve leaking?
A leaking valve normally occurs when the spindle packing contained within the valve starts to wear out or becomes damaged. This type of leak will normally occur when the valve is in a ‘mid-open’ position the leak will normally stop when you fully close the valve.
Is it cheaper to leave heat on all day?
Simply lowering your heat 10 to 15 degrees for eight hours a day could save you anywhere from 5 to 15 percent of your energy costs each year, according to the U.S. Department of Energy, or about 1 percent for each degree you turn back the thermostat.
