Worcester Bosch Flow 8000 40 D Direct Heat Interface Unit Overview

The Worcester Bosch Flow 8000 40 D direct heat Interface unit comprises of one heat exchanger to provide instant domestic hot water at up to 60°C, direct heat of up to 15 kW of heat and for underfloor heating. These heating appliances are popularly used to provide heat and hot water to communal properties, such as apartment blocks, to provide an energy-efficient heat source through a network of pipes to supply hot water and heating to each resident on demand.

A Keep-Warm Function, an Accurate Electronic Control Valve and More

The Flow 8000 40 D adapts for optimal performance in various primary flow conditions and has a fast-acting electronic control, including a return temperature limiter function. This heat interface unit delivers low-carbon heating even in low temperatures for maximum performance and minimum temperature loss. Using this heating appliance can reduce maintenance and call outs, and it's also a great option to switch to smaller radiators to preserve space in more compact properties.

This heat interface unit includes an accurate electronic control valve and a keep warm function to provide instant hot water. You can integrate it easily with any 230V third-party heating control system, or use the Worcester Bosch Sense II controller for sophisticated control options. Finally, make use of the internal pre-payment connection to disable the domestic hot water and heating operation from an external metering.

How This Heat Interface Unit Works

This heat interface includes a separate first fix rail pipe work jig so you can pre-plumb the system before the unit is installed. The Worcester Bosch Flow 8000 40 D direct heat interface unit's primary heat supply is hydraulically separated for DHW production whilst space heating is a controlled direct supply to the apartment heating system, and it seamlessly integrated with heat pumps. The Worcester Bosch Flow 8000 40 D is available with various optional accessories, so it's suitable for various situations, and it works alongside other heat sources for an energy-efficient, cost-effective heating solution.
