Maris Water Hub Mixing Valve

Maris Water Hub Mixing Valve. If you do not have mains hot water, for example if you have a gravity-fed system, you can use this Mixing Valve component to blend the boiling water from the tank with your mains cold feed, in order to provide up to 55°C warm water. In other cases, if a mains hot water supply is present but takes a long time to reach the kitchen tap, this valve acts as a bypass integrating the mains water with the boiler to offer hot water instantly to the tap.
