These Maesta TRV Straight Thermostatic Radiator Valves in Brushed Brass are designed for homeowners seeking elegant temperature control and energy efficiency in traditional heating systems. They offer precise room-by-room heat management, leading to potential energy savings and personalized comfort. A key consideration is their non-bi-directional nature, requiring specific installation on the flow and return pipes for optimal function.

No, these radiator valves are not bi-directional. The thermostatic head must be installed on the flow pipe, and the lockshield valve on the return pipe for correct functioning.
The lockshield valve is used to balance the heating system. Once the TRV is set, the lockshield is adjusted to ensure water flows correctly through all radiators without bypassing others.
The frost protection is typically activated when the TRV head is set to the lowest setting, often indicated by a snowflake symbol. This allows a minimal flow of water to prevent the radiator and pipes from freezing in cold conditions (below 7°C).
These specific valves have a polished finish in Brushed Brass, designed to offer a premium, durable aesthetic.
The compression inlets are 15mm, and the radiator coupler is 1/2 BSPT.
The valves are constructed from heavy-duty solid brass, with a wooden top handle.
Yes, these valves are compatible with standard water radiator systems, including those connected to combi boilers, provided the pipework is compatible.
Ensure the lockshield valve is open and the TRV head is not set to the lowest setting or 'frost protection' (indicated by a snowflake symbol). Verify the valve is installed correctly on the flow pipe.
Check that the TRV head is set to the desired lower temperature. Ensure the thermostat head is not obstructed by curtains or furniture, which can prevent accurate temperature readings.
Check all compression fittings and connections are tight. If the leak persists, contact a qualified plumber for inspection and potential replacement.
The TRV head may have become detached. Gently re-secure it to the valve body according to the installation manual. Ensure it clicks into place.
Ensure the TRV head is not fully shut off. The frost protection setting (often marked with a snowflake) should allow minimal water flow below 7°C to prevent freezing.
