Frequently Asked Questions

Can this valve be used on any standard radiator?

Yes, as long as the radiator has a compatible 15mm pipe connection and 1/2" tail fitting, this valve will fit most standard radiator systems.

What’s the difference between a wheel head and a thermostatic valve?

A wheel head valve offers manual control—you turn it to open or close the flow of hot water. A thermostatic valve (TRV) automatically adjusts based on room temperature, offering more efficient temperature control.

Is this valve suitable for both open-vented and sealed heating systems?

Yes, the Evolve Contract range is compatible with most domestic heating systems, including both open-vented and sealed (pressurised) systems, as long as pressure and temperature limits are observed.
