Our Heat Interface Units are designed and manufactured in Sheffield of which the selected equipment for each scheme is assembled by our experienced, skilled production operatives.

All the different types of assemblies manufactured to suit the particular scheme not only in the selection of control items but in the layout of the finished product for ease of site installation.

Control boards subjected to checks on electrical wiring and pressure tested to the customers requirements.


Quality Assurance

Pre-delivery checks, packaging and delivery to the location specified by the customer.

All types of consumer control ‘packages’ from basic direct connection units to the application of plate heat exchangers either for hydraulic separation or to create instantaneous mains pressure domestic hot water.

Control assemblies are tested before mounting and can be fitted to all types of domestic hot water cylinders to suit the particular scheme.
