Whale Seaward Thermostatic Water Mixer Valve

The Whale Seaward Thermostatic Mixer Valve is a plumbing safety fitting built for the Whale Quick Connect system, blending hot and cold water to a set temperature before it reaches the tap rather than leaving scalding-hot water straight from the heater.

It uses three 1/2-inch BSP male threaded ports and is constructed of nickel-plated brass, including a built-in non-return valve that keeps water from flowing backward through the system.

Each BSP threaded connection is fitted with an O-ring for a reliable seal, a straightforward add for any Whale water heater install that doesn't already have temperature mixing built in. Explore more water heaters.
