HORNE H25-11B TMV3 MIXING VALVE Standards and Approvals

All materials in contact with water are WRAS approved.
All HORNE products are manufactured under our Quality Management System to BS EN ISO 9001:2008.  Certificate No. FM01224

Thermostatic mixing valves (TMVs) mix the hot and cold water supplies to produce a temperature-controlled flow. The hot water supply is typically around 60°C, and is maintained at this temperature to prevent the growth of harmful organisms, such as Legionella bacteria.  A supply of higher temperature water is also required for cleaning and washing purposes in the kitchen and laundry while also increasing the overall capacity of warm water (mixed with cold) to the building. Water at 60°C, however, can scald and so it is mixed with cold water, at the point of discharge, to produce a flow at a safe and comfortable temperature of 41°C.
