Servicing and maintenance Our service engineers provide annual health checks, fault-finding, repair and maintenance services on existing HIU, thermal store, thermal bank, (district) heat networks and substations.

Heat network optimisation Our team has decades of experience designing existing heat banks, HIUs and substations. We are the best fault-finding and optimisation experts for any type of heat network in the UK.

Energy efficiency monitoring Our unique and innovative technology has been refined over many years and is protected by numerous patents relating to water storage, heat exchange and the networking of communal heating systems.

         

The HiFlow CH is an extremely powerful single plate HIU, designed to provide heating for larger domestic or commercial properties.  Its modular design enables it to be mounted into a supporting frame with several more HiFlow modules all connected via a manifold to provide very large heating outputs.

The CH module can also be fitted alongside various different modules including hot water, underfloor manifolds, air handling units, BMS and more, to form a compact yet powerful bank of modules to cater for all the needs of the property.

The HIU is fitted with the latest digital electronic control valve to ensure pressure independent control but to also exchange accurate information about the actuator/valve position, settings, temperatures, & alarms.  It also comes equipped with ModBus communications as standard.

The HiFlow comes in an attractive EPP casing and the internal components and pipework is fitted with secondary insulation to give remarkably low heat losses less than 50W. All pipework connections are bottom entry and there is an are option of rear entry pipework.  Support frames and manifolds are also available for mounting up to 3 modules in parallel to form a powerful substation.

Items such as the pump, expansion vessel and safety relief valve must be fitted external to the casing, and are available from HEATWEB on request.
