RMC’s HeatGuard® is a tempering valve that mixes hot and cold water to deliver tempered water at a constant temperature throughout an entire building or system. HeatGuard® is suitable for the delivery of safe, constant tempered water to rooms intended for personal hygiene, such as the bathroom and ensuite, where outlet temperatures must not exceed 50°C. HeatGuard® is compatible with most hot water distribution systems. Its compact design requires minimal space and is available in 15mm and 20mm configurations.
