The Elegance 15mm Angled All-Chrome Thermostatic Radiator Valve (TRV) combines automatic temperature control with a premium, fully chrome finish for installations where appearance matters as much as performance. The thermostatic head responds to room temperature and adjusts flow into the radiator, helping maintain a consistent temperature while reducing unnecessary heating.
The angled 15mm body suits pipework running horizontally into the radiator, maximising clearance and keeping the installation tidy. A liquid-fill sensor gives stable, responsive control, and the all-chrome finish coordinates cleanly with modern chrome valves, towel rails and column radiators.

Good to Know
The temperature scale runs from a frost-protection marking (*) through to setting 5, giving an adjustment range of approximately 7°C to 28°C. A measured response time of 24 minutes and a water temperature effect of 1.40 K reflect the valve's stability under normal domestic heating conditions.
Full Chrome Finish
A premium, fully chrome-finished valve body and head for a smart, modern appearance that suits designer and traditional radiators alike.
Angled 15mm Design
Ideal where pipework runs horizontally into the radiator, keeping the installation low-profile and free of visual clutter.
Liquid-Fill Sensor
Stable, responsive thermostatic control that reacts smoothly to changes in room temperature.
Bi-Directional Body
Suitable for use on flow or return pipework, giving flexibility when planning the installation.
Simple Temperature Scale
Clearly marked dial from frost protection (*) to 5, making it easy for homeowners to set and adjust.
Standard UK Connection
15mm compression connection for standard 1/2" BSP pipework, compatible with typical UK radiator setups.

What does the * setting on the dial mean?
The * marking is the frost protection setting, which keeps the valve open enough to prevent the radiator and nearby pipework from freezing in an unoccupied or unheated room, corresponding to roughly 7°C.
Will the all-chrome finish match my other bathroom or kitchen fittings?
The valve is finished in all chrome, which is designed to coordinate with typical chrome taps, towel rails and column or designer radiators commonly used in UK bathrooms and kitchens.
Is this valve suitable for a towel rail?
Yes, it's suitable for domestic radiators and towel rails on standard central heating systems, provided the pipework uses a compatible 15mm angled connection.
How long does it take to respond to temperature changes?
The valve has a measured response time of around 24 minutes, which is typical for a liquid-fill thermostatic sensor and allows it to react smoothly without overshooting the target temperature.
Does this need a separate lockshield valve?
Yes. This listing covers the angled TRV only; a lockshield valve is fitted at the other end of the radiator to balance flow across the system and is sold separately.
