JG Speedfit has launched a wireless thermostatic radiator valve, the JG Aura TRV, designed to efficiently regulate hot water to each radiator in a house. The JG Aura TRV simply replaces traditional radiator valves, making installation quick and easy. The valves are controlled wirelessly by a JG Aura thermostat in every room and can send a signal to the JG Aura Network, turning the boiler off when room temperature has been reached.
