However this in not the case now and most, if not all, TRVs are universal, meaning that the flow can be either way through them without making and alterations to them. This means that there is no restriction to which side of the radiator they can go.
Will thermostatic radiator valves fit all radiators?
If your boiler is fitted with a flow meter that detects when all of your radiator valves are closed, you can install a TRV on every radiator if you want to. You can leave any radiator without a TRV, but it makes more sense for you to select the radiator in the room with your wall thermostat.
Are radiator thermostat valves universal?
The connection between your valve and the radiator is standard across all moderns radiators and valves. The size differences listed above refers to the width of your pipes that the valves will slot onto.
Can you put a thermostat on any radiator?
Thermostatic valves can be fitted on any radiator, except the room where the main thermostat is located.
Are thermostatic radiator valves a standard size?
15mm valves are the only size you’re likely to encounter, since 15mm copper pipes are the most common. There are also other sizes, from 8mm to 28mm, and there are accompanying adapters.
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.
Why do you have to a one radiator without a thermostat?
The thermostat controls the boiler and turns the boiler off when the air temperature (yes recorded in one place usually the hall or lounge). The radiator valves do not control the boiler and at least one radiator should be on all the time (have no control).
Can you mix and match radiator valves?
Don’t mix and match Need to add or change a radiator? Stick to the same type of metal. Introducing more than one type of metal radiator into your heating system can increase the risk of corrosion.
How do I know what radiator valves to buy?
Side connections with pipes coming up from the floor = you need angled valves. Underside connections with pipes coming up from the floor = you need straight valves. Side connections with pipes coming out of the wall = you may choose between angled or corner valves.
Why do radiators have 2 valves?
Radiator valves are necessary in whatever form as they allow an easy way to stop the flow of the central heating circuit into the radiator.The reason you need two valves generally on all rads is because the system dictates a flow and return. The flow pipework carries the newly heated water from the boiler.
Is it easy to fit a radiator thermostat?
A thermostatic radiator valve gives you more automation over the temperature at your home. To that, the device lowers your monthly energy bills. The fitting process is fast and simple, but there are some details you need to know to avoid damages.
Can you turn a radiator down without a thermostat?
Non-thermostatic valves
Step 1: Also known as a manual valve, find the non-thermostatic valve on the left or right side at the bottom of your radiator. The other valve on the radiator will be fixed or will be capped. Step 2: To turn your radiator off, turn the valve clockwise as far as it will go. Top Tip!
Do radiator thermostats save money?
Can you save money by using TRVs? TRVs can save you money because they allow you to heat your home more efficiently and in a smart way that is appropriate to each area of the home.This means that radiators don’t produce unnecessary heat.
Do both radiator valves need to 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 size are radiator bleed valves?
Castrads bleed valves can be used with a wide range of cast iron radiators. Most steel multicolumn radiators use half-inch 21mm BSP bleed valves.
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.
Is it worth fitting thermostatic radiator valves?
Yes! Thermostatic valves are the best way of getting the heating in your home just right! Used in combination with a room thermostat, they adjust your heating perfectly, and you won’t end up with some rooms being overheated.
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.
Can you put a TRV in the same room as a thermostat?
The installation of a TRV is really to provide individual room comfort.Neither arrangement is faultless and ideally every room could do with a room thermostat however, this isn’t practical and the suggested method has the better results.
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.
Why does one radiator always have to be on?
The way combis work (and some older boilers) is that when the boiler heats up to make instant hot water it (the boiler) gets hot. You turn the tap off and the boiler still has lots of heat so it needs to dump that heat and uses the one mandatory open radiator to cool the boiler.
