The best way to use thermostatic radiator valves is to decide on a comfortable room temperature and set the number on the TRV accordingly. Regularly changing the settings on a TRV is not recommended and will undermine their money saving qualities, which is one of the main benefits of installing them in the first place.
What should thermostatic valves be set at?
Approximate conversion into degrees Celsius
| Valve position | Reference temperature | Recommended setting for |
|---|---|---|
| 2-3 | 18°C | Bedroom |
| 3 | 19-20°C | Kitchen |
| 3-4 | 20-21°C | Lounge, child’s bedroom |
| 4 | 22°C | Bathroom |
How do you balance radiators with thermostatic valves?
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.
Does it matter which side a thermostatic valve goes on a radiator?
The vast majority of new TRV’s are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.
Should both radiator valves be open?
You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.Once this is done your radiator system should be fully balanced and your radiators should heat up evenly and efficiently.
What do numbers on thermostat mean?
You will see a number on the thermostat display. This number is the ambient temperature in your home. Use the up and down arrows on the thermostat to set the temperature you want the home to reach. You will see a different display number come up that corresponds to the temperature you set.
Which way do you turn a radiator valve?
Turn valves clockwise to turn your radiator off and anticlockwise to turn it back on. Turning your radiators off is easy.
Do you bleed a radiator when it is on or off?
Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.
Do you need to balance radiators with thermostatic valves?
A TRV is a proportional controller, i.e it adjust the flow through the rad according to the difference between actual and desired room temperatures. A TRV will act as an on/off switch if the pressure drop across the valve is too high. Balancing is needed to make sure the mean flow rate through the valve is correct.
Should lockshield valve be open or closed?
When the radiators are cool, switch the heating back on and go to the first radiator on your list. Turn the lockshield valve clockwise until it is closed and then open it by a quarter of a turn. Once the radiator has warmed up, take a temperature reading at the pipework leading to one of the valves (7).
How far should I open a lockshield valve?
You should open the Lockshield valve on the first radiator by one-quarter of a turn. Now open the Lockshield valve on the last radiator on your list. Each radiator in between should have its Lockshield valve opened slightly more than the previous radiator.
Should TRV be 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.
Do radiators have a flow direction?
Pipes from one radiator lead to another and do not cross, so you orient the radiator the same way as the other radiators on the same floor are oriented. If you only have one radiator, you will need to get into your neighbor’s apartment to figure out which way the pipes are going.
Which side of the radiator is the flow?
left
The flow of a radiator is typically on the left as you look at it stood up or attached to the wall.
Should I open my radiator all the way?
“It’s not designed to be a control valve,” he says. Typically you turn the knob clockwise to turn the heat off, counter-clockwise all the way to turn the heat on. If the radiator is off, it shouldn’t make any banging sounds. “When you have it opened halfway, that can lead to banging problems,” Varsalona says.
How do I make my radiator hotter?
- Locate the main boiler for the radiators.
- Turn the boiler thermostat up to a higher temperature.
- Adjust the temperatures on the individual radiators by turning the wheel valves counterclockwise to raise the temperature, or clockwise to lower the temperature.
Why do we need 12 degrees when balancing radiators?
Then on the other side of the radiator check the temperature of the pipe leading into the secondary valve or TRV. The goal is to achieve a temperature difference between the two figures of 12 degrees where the lockshield valve temperature is 12 degrees higher than the exit valve’s temperature.
How do I make my thermostat colder?
A: To adjust the thermostat in either temperature, turn the dial clockwise to make the unit colder and counter clockwise to make the unit warmer.
How do you program a thermostat efficiently?
During the summer, program your thermostat for 78 degrees when you’re home. During the winter, program it for 68 degrees when you’re home. Program your thermostat to reduce heating or cooling 60 minutes before you go to bed at night and to increase heating or cooling 30 minutes before you rise each morning.
Do you turn the thermostat up or down for cold?
When you lower the temperature on your thermostat, the air conditioner turns on and begins to cool your home.However, the air conditioning can’t work any harder than that to cool your home. So, turning down your thermostat by 10 degrees won’t cool your home any faster than if you turn it down by two degrees.
Should you bleed radiators when hot or cold?
Do You Bleed Your Radiators With The Heating On Or Off? You should always bleed your radiators when the heating is switched off and the system has cooled down, because bleeding radiators with hot water flowing through the system increases the risk of scalds and burns.
