Bosch launches new and improved Heat Interface Unit

16 Feb 2017

Bosch Commercial and Industrial has added to its range of energy efficient heating, cooling, and hot water technologies, by launching an enhanced version of its heat interface unit (HIU).The new addition will provide domestic hot water and space heating to properties that are serviced from district heating or centralised boiler plants.

The new HIU features a series of improved benefits such as an ErP compliant modulating space heating pump, and internal system filters on district, central heating and hot water circuits. The easy-to-install unit can be supplied with or without a heat meter and is compatible with the entire Bosch Commercial and Industrial product range.

The new update means the manufacturer can supply four HIU models with flow rates ranging from 14 litres/min to 21 litres/min. Additional accessories can be included with each model, with the highest output model available with summer by-pass, a Differential Pressure Control Valve (DPCV) and a premium glass outer case as standard. The hot water and heating temperature can also be fixed during the commissioning process.

A keyless filling link is also fitted as standard on all new HIU models and is connected from the district/primary side to the heating side so that treated water enters the system. What’s more, the HIU is fully insulated with EPP insulation on the front and rear of the appliance, significantly reducing heat loss and minimising system noise compared with non-insulated HIUs.

Shaun Mansbridge, Business Development Director at Bosch Commercial & Industrial, said: “The HIU is the perfect solution for district heating and applications with a centralised plant room, providing both domestic hot water and heating. The advanced HIU is now 10 bar district pressure compatible (in-direct) which is a significant improvement on the appliance’s predecessor. What’s more, its multiple options make it a flexible product that can be tailored to the requirements of different district heating networks and boiler plants.”
