Top Specifications

Receive an on-demand heating solution for heat networks where optimisation for low temperatures is required. The Worcester Bosch Flow 8000 50 D direct heat interface unit offers a maximum differential pressure of 4.5 bars, and the single-plate heat exchanger delivers domestic hot water at flow rates of 21 litres per minute for water on-demand. In fact, this Worcester Bosch heat interface unit includes an electronic control valve and a keep warm function for instant hot water.

How This Heat Interface Unit Works

The Sharkey 775 heat meter option uses standard M-Bus communication systems connect to a wired or wireless Mbus as standard.

Use the internal pre-payment connection to disable the domestic hot water and heating operation from an external meter. This added option also means there are no additional solenoid valves, just the heat interface unit's internal two-port control valves.
