Worcester Bosch Flow 8500 40 Indirect Heat Interface Unit Overview

The Worcester Bosch Flow 8500 40 indirect heat interface unit is ideal for multiple use, without disturbance to the flow rate, even at peak times. This unit is a great solution for district hot water and space heating to properties that are serviced with district heating and applications with a centralised plant room.

Reliable Performance

Sporting a reliable design and excellent performance, it's built to withstand the demands of future heat networks, while providing instant domestic hot water and maintaining efficiency simultaneously. This heat interface unit includes a keep warm function and precision temperature sensors to provide accurate control at very low flow rates.

Two Heat Exchanges

This Worcester Bosch unit comprises of two heat exchangers, one for providing instant domestic hot water at a regulated temperature and the other for space heating within the property. The Worcester Bosch Flow 8500 40 indirect heat interface unit is indirect so the primary heating circuit is separated from the property space heating only and operates when domestic hot water or space heating is required.

Keep Heat Losses at Bay

This Worcester Bosch heat interface unit retains heat, making it energy efficient, and the high-performance plate heat exchanges meet many of the best practice requirements under the BESA 2023 Test Regime to remain optimised for low temperature heat networks.

Flexible Usage

The Worcester Bosch Flow 8500 40 indirect heat interface unit features smart software for increased flexibility over temperature set points, ensuring it meets the standards required of modern low temperature.
