The HiFlow HIU is a Single plate high output HIU designed to cater for your larger central heating or hot water requirements. These are available as individual units, but can also be frame mounted with several other HiFlow modules to create a modular substation. Please refer to our article on The Cupboard HIU

Each module is built into an Expanded Polypropylene (EPP) casing, which provides fantastic insulation properties. The plate heat exchanger and pipework is insulated within this casing, to minimise heat loss as much as possible.

Each HiFlow is fitted with our latest Heatweb BEMS Controller, together with a pressure independent control valve and Modbus enabled actuator. This enables the output of the HIU to be controlled based on feedback from several NTC sensors mounted on to the pipework.

The HiFlow can be fitted with a pump and safety relief valves for Central heating applications, and all DHW models are fitted with a flow sensor to enable the output of the unit to be controlled based on temperature and flow rate.
