## Description

Hot Flow Black Nickel Marella 3 Modern Thermostatic Radiator Valve Corner TRV. Includes Corner TRV Body, Wheel Head & Lock Shield for Quick & Easy Temperature Control.

## Features

- The Marella valve set consists of a thermostatic radiator valve head, a Corner TRV body and one lockshield, giving you the necessary radiator accessories to control the temperature in your room quickly and easily. We also provide decorators caps (used to fully isolate TRV valves whilst a radiator is removed for decorating) and full installation instructions for further convenience.
- Our Black Nickel Thermostatic Radiator Valves are constructed from Brass and finished in a plated coating, ideal for Black Nickel radiators or towel rails. The radiator thermostat valve has a smooth action allowing for six settings to achieve the perfect ambient temperature and will still operate if the room falls below 7°C providing frost protection to your heating system.
- Thermostatic radiator valves are energy saving, environmentally friendly, and make it possible to control the temperature in your room effectively. Simply set the temperature that you desire and the radiator will automatically reach the required heat output - the heat sensitive mechanism within the TRV will detect any changes to the atmosphere and adjust the amount of hot water that it allows into the radiator, keeping your home at a constant and comfortable temperature.
- We recommend all TRVs are installed on the flow rather than the return pipework of a radiator. When used in conjunction with a system automatic bypass valve this thermostatic valve can be installed on either the flow or return in any orientation. System automatic bypass valves are a specific building regulation requirement for all new installations and boiler upgrades. All bi-directional TRVs from any manufacturer require the bypass valve to function correctly and thus avoid radiator hammer.
- Corner valve sets are most suited to situations where the central heating pipes emerge from the floor and where the radiator valve feeds are at the side of the radiator. On occasions they can be used with radiators where the pipe entry feeds are at the bottom, although we would always advise checking with the installer to see what will be most suitable for your project.
- Black Nickel TRV - The Black Nickel may not match all Black Nickel on the market.
- Head Thread is M30 x 1.5 so the TRV body can fit most Smart radiator valve heads.

good valve don't see why the price is so high compared with normal valves orthe wise would have given 5 stars

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Issue with compatibility
  

*by M***Y on Reviewed in the United Kingdom on 23 November 2023*

We found that interchanging TRV's seem to cause a problem with some manufacturers. The corner jigs are about 3mm too long to insert into existing pipework (we had others spare corners fortunately) but a pain and time consuming to take that small amount off.
