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.
What side does the thermostatic valve go on a radiator?
Many modern homes will have TRVs Thermostatic Radiator Valves attached to most of the radiators on the opposite side from the lockshield valves. A TRV should always be fitted to the inlet on the radiator and the LSV to the outlet.
Does TRV go on Inlet?
Where Should I Fit a TRV? Many thermostatic radiator valves nowadays are bidirectional, and you can install them to either the flow or the return pipe of your radiator. However, we would advise you to fit the TRV on the pipe that carries water to your inlet valve the flow pipe.
Which side of a 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.
Do thermostatic radiator valves work upside down?
Yes they can be installed upside down.
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.
How does flow and return work?
What Boiler Flow And Return Pipes Are. As your boiler heats up water, it’s pumped out and circulated around your central heating system; this hot water comes out of the flow pipe. The water then travels around your heating system and returns to the boiler via the return pipe.
Can the TRV be on the return?
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.
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.
How does a thermostatic radiator valve work?
How do Thermostatic Radiator Valves Work?The thermostatic valve head goes on top of the valve body. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes. Expansion as the room heats blocks the valve body to receive less hot water into the radiator.
Which is flow and return on radiator?
The flow pipes are connected to one end of the manifold in a number of radiators, and then return to the other end. But both the feed and return microbore pipes are connected to the same end of the radiator.
Does it matter which way round a radiator goes?
Mistake 2 Orientation of the radiator
If you fit the radiator in the wrong orientation it can result in a reduction of output, noise from the heating system, or even in extreme cases you can end up with a radiator that doesn’t do anything other than take up wall space. This also goes for the valves.
Should radiator valves be open or closed?
Check the temperature
One should be on the pipe that allows water into the rad and the other should be clipped onto the pipe where water flows out of the rad.This can be done on every radiator and each lockshield valve may have to be open or closed to a different degree in order to achieve a temperature balance.
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.
Can a radiator be installed backwards?
A word about installation: It is possible to install an engine fan backwards.That is, if a correctly installed fan draws air through the radiator, an incorrectly installed fan still draws air through the radiator it does not blow air through the radiator. Here is a picture of a fan correctly installed on its drive.
How do I know if my radiator is flowing?
One Way Is By Checking Coolant Flow:
- Start off with a cold engine.
- Remove the radiator cap.
- Start up the engine and let it idle.
- Verify that the coolant is not flowing.
- You can check this by looking through the radiator filler neck.
- The coolant should not be flowing.
Does pump go on flow or return?
The best place for the pump(s) is still on the flow side. This keeps the bulk of the system under positive pressure from a combination of the pressure imposed by the system water connection, and then when the pump is running, the pressure provided by the pump.
What does flow return reversed mean?
What does it mean if the flow and return are reversed. The flow is where hot water leaves the boiler. The return is water that has been circulated around the heating system and is coming back to be reheated again. When the flow and return are reversed, the boiler won’t work correctly.
Does the flow pipe get hot first?
the flow pipe heats up first obviously. Flow gets hot first.
What is a bidirectional TRV?
The Danfoss family of thermostatic radiator valves (TRV) has a new addition with the launch of the RTW bi-directional TRV with built-in sensor.RTW also benefits from Danfoss’ flow selectable, bi-directional design which means it can be installed horizontally or vertically, in flow or return.
Which valve is which on a radiator?
One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
