Building Regulations state that all new and modified wet central heating systems must have a TRV fitted to every radiator (apart from one where the room thermostat or programmable thermostat is installed, typically in the hall).
Generally, one radiator should be left without a TRV and left permanently switched on, unless the boiler is fitted with a flow meter to detect when all the radiator valves are closed. … Some TRVs are prone to sticking at one setting, if they’re never adjusted.
Beside this, Can you put a TRV on any radiator?
Standard practice is to leave one radiator without a thermostatic radiator valve installed, and to leave that appliance permanently switched on. 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.
Likewise, 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).
Also, Can TRV go on either side?
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.

Why is one radiator on when heating is off?
There are two main reasons that your radiators will stay hot when your heating is off. It normally comes down to a problem with either your diverter valve or your check valve. … They’ll run some tests and establish whether it is indeed a check valve or diverter valve at fault – or a different underlying issue altogether.
Can you fit a TRV upside down?
Yes they can be installed upside down.
Do all radiators need thermostatic valves?
However, while TRVs can, technically, be installed on all radiators, it’s usually a good idea to leave one radiator without a TRV and permanently switched on. Ideally, this should either be a bathroom, which would usually benefit from permanent heat, or the room with the thermostat in it.
Do all radiators need TRVs?
However, while TRVs can, technically, be installed on all radiators, it’s usually a good idea to leave one radiator without a TRV and permanently switched on. …
Do radiator valves need thermostatic?
Doesn’t your heating equipment have thermostatic valves yet? It’s always a good idea to fit some! 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.
Which side of a radiator does a thermostatic valve go?
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.
Are TRV heads Universal?
Sadly not. The mechanism attaching the heads to the body tend to be unique to each manufacturer – if you’ve got a branded valve then it’s usually possible to get a new part.
Can a boiler work without a thermostat?
Quite surprised that if it’s a new boiler there is no thermostat as it’s part of building regs that all new installs should have one along with TRV’s. … The boiler will run until the high limit stat reaches temperature. Once it cools sufficiently it will run again.
How much money do TRVs save?
Energy efficient heating with TRVs In fact, the use of TRVs has been linked to energy savings as significant as 40%.
Can radiator valves be fitted upside down?
Unfortunately the valves cannot be installed upside down.
Where do you put a thermostatic radiator valve?
The TRV is a valve that self-regulates, meaning it adjusts the flow of water into your radiator depending on the setting. 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.
Do thermostatic radiator valves save money?
Energy efficient heating with TRVs Namely, one consisting of a single centralised boiler and one room thermostat. This will enable the valves to heat your home in an energy efficient manner, and not waste heat on empty rooms. In fact, the use of TRVs has been linked to energy savings as significant as 40%.
