As simple as they are revolutionary.

 Balancing radiators in a heating system seems like it should be simple, yet it is difficult, time-consuming, and often pretty inaccurate. No more!

• Quickly, easily, and effectively balance radiators, ensuring each room gets the correct amount of heat
• Say goodbye to some rads that get too hot, and others that never do.
• Perfect for use with heat pumps, especially with open-loop, weather-compensated systems.
• Great for conventional gas, oil, and biomass boilers, in both new and existing systems.
• Keep the TRVs if you want, because the FRV only takes the place of the lockshield.
• 15mm compression fitting, with an extra seal between the FRV and radiator.
