Be sure to prevent scalding, says Honeywell

Published: 15 September, 2009

Schools and nursery schools should ensure children and staff cannot be scalded by hot water by fitting fail-safe thermostatic mixing valves (TMVs) on hot water outlets, says Honeywell, the leading manufacturer of water valves and heating controls.

The valves control the hot and cold water inlets to provide a constant, safe, preset temperature at the point of delivery. They ensure safety by cutting off the hot water inlet automatically if the cold supply fails.

Regulations demand TMVs on baths and showers, but they should also be fitted to hand basins, advises Honeywell. The scale-resistant Honeywell TM300 is designed for installation on both high and low pressure systems, and certified to the Buildcert TMV2 scheme for installation on baths. It is therefore acceptable in all schools and nurseries except those used by the severely disabled; these require a valve such as the Honeywell TM200VP, rated to the higher TMV3 standard.
