A correctly controlled domestic central heating system provides a better comfort level, uses less energy and produces lower CO2 emissions. Responding to signals from other controls such as programmers and thermostats motorised zone valves control the flow of heated water to radiators and hot water storage cylinders. They are therefore an essential component of any modern central heating and hot water system. Our ZonePlus range of two and three port valves combine proven electronic and mechanical controls technology with the latest design features for easy installation and maintenance.
