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 SLIM Extra HIU is based on the SLIM HIU, however this unit is fitted with an additional combined automatic balancing and control valve, with pipework to connect directly to the central heating system.  The HIU is fitted with a tamperproof steel casing, ideal for less secure environments.
