The flow of a radiator is typically on the left as you look at it stood up or attached to the wall.
Does it matter which side of radiator flow and 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.
Can a radiator be fitted wrong way round?
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. … While this doesn’t cause any damage to the system it is very annoying.
Does a radiator 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.
Does it matter which way round you plumb a radiator?
A normal radiator or towel it doesn’t matter. If the radiator is not fitted, then the tails will not heat up. Fit the radiator, if it’s the wrong way round, all you have to do is swap the rad valves round – I think the instructions will just be referring to the TRV’s, nothing to do with the radiator itself.
Which side of radiator is the lockshield valve?
The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don’t accidentally change the setting once you’ve adjusted it.
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.
Should radiators be put under Windows?
The traditional place to position your radiator is the coldest part of the room. Whether that’s beneath your window or against the wall. This is due to conduction, with incoming cold air causing more effective heat conduction and pushing the hot air from your radiator into the middle of the room.
What side of the radiator does the thermostat go?
However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator. If a non-bi-directional thermostatic valve is fitted to the return side of the radiator, it can make a loud vibrating noise when water tries to pass through it.
Are oversized radiators better?
Getting the balance right with radiator size is critical. If your radiator’s too big, you’ll be wasting energy every time it’s on – and you may be taking up unnecessary wall space. Then again, if your radiator’s too small, you’ll never get the heat output you need to get the temperature you want in the space.

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.
Do vertical radiators have a flow direction?
It is very unlikely they have dedicated ‘sides’ and should be fitable either way around. Ditto with these valves – the TRVs are bi-directional so can be fitted to either end, flow or return.
What are the two valves on a radiator for?
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.
Should radiator valves be open or closed?
When you take the temperature of your radiator and valves you’ll be making tiny adjustments. … You close the first radiator’s valve and then open it gradually until you have reached the desired temperature. If your radiators are not balanced, it will be harder to achieve the desired temperature if they are already on.
What happens if flow and return are reversed?
If the pipes are reversed, the sensor will record the lower temperature and could compensate to make up the difference. This can result in unwanted noise, or overheating and inefficiency.
Is the lockshield valve in the flow or return?
A lockshield valve (LSV) is 1 of 2 radiator valves that control the flow of hot water through each radiator. It’s typically placed on the return pipe, and derives its name from the plastic cap that protects the valve from being accidentally turned.
Is radiator valve same as lockshield?
The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room. … In doing so, you will be able to pick the radiator and radiator valve that is most suitable for your needs.
Should radiator lockshield 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).
Which pipe is the inlet on a radiator?
Radiator Valve Inlet Positions Standard radiators (commonly known as compact radiators) typically have side valve inlets. These are located at the bottom of the radiator too but tend to allow access from the side only (horizontally).
Where is the bleed valve on my radiator?
The bleeder valve on the radiator is usually situated at the top of the radiator and can be at either end. It’s round and has a square section in the middle with two notches. This is where you put the bleed key (or screwdriver) to drain the radiator to let the trapped air escape.
Where is the best place to position a radiator in a room?
The best place for a radiator is in the coldest part of the room. This used to be under windows. However, in more modern double-glazed homes, there may not be a cold area, so you can put radiators where they won’t affect the use of walls. A general rule is to have one radiator for every 4m or so in a room.
Does putting a sofa in front of radiator?
It’s not a good idea to place a sofa, or any other large furniture, in front of a radiator. A sofa would block heat from travelling freely around the room, and could suffer potential long-term damage from a close level of heat exposure.
Is it cheaper to leave central heating on constant?
According to experts at the Energy Saving Trust, the idea it’s cheaper to leave the heating on low all day is a myth. … The Energy Saving Trust says if you’re keeping the heating on all day you’re losing energy all day, so it’s better to heat your home only when you need it.
Do bigger radiators give off more heat?
The longer the panel, the larger the heat emitting surface area, so bigger radiators will emit more heat, but also remember that a double panel radiator will emit more heat than a single panel radiator of the same length.
Will a double radiator make room warmer?
The longer the panel, the more surface area there is for the radiator to emit heat. Therefore, a radiator with a double panel of the same dimensions as a single panel radiator will give off more heat, as the total surface area is greater.
How high should radiators be off the floor?
Radiators should typically be mounted so that the foot of the radiator is positioned a minimum of 150mm from the floor. The height of nearby floorboards could influence how high a radiator is fitted, if only for aesthetic reasons.
Where do radiator pipes run?
The pipework is normally either run between the joists or across the joists through cut-outs cut in the top of the joists. Except for microbore, the pipework should be supported below the floor boards to avoid excessive weight having to be supported by the pipework itself.
Which is the return pipe on radiator?
A second pipe (called the ‘return pipe’) collects the cooled water from the radiators and carries it back to the boiler for re-heating.
Which way does water flow through a central heating radiator?
As mentioned, this hot water heats the room via convection. The hot water doesn’t remain in the radiator, instead the hot water flows through the radiator and out again to the next radiator in the chain. As the hot water flows through the system it starts to cool down.
Can vertical radiators have valves at the top?
Em yes you can connect the radiator up TBOE, top, bottom opposite ends.
Do radiators have a top and bottom?
Radiators are naturally warmer on top than the bottom, but some radiators more than others. … All radiators use a combination of both convection heating and simply ‘radiating’ their heat out. Therefore, most radiators will feel cooler at the bottom, but no radiator should be completely cold at the bottom.
