No two schemes are the same! ! !
All Heat Interface Units (HIU’s) produced by HeatLink (Technical Solutions) Ltd. are designed specifically for each scheme.
All HIU’s are made to specific requirements as we believe each scheme is unique and our solution often necessitates bespoke units for each individual application.
The components and controls included are specifically selected based upon the operating criteria of the particular system and the requirements of the scheme designer, operator and consumer. Additionally, by designing each board specifically for the scheme considered we can configure the physical size of the unit and layout of the connecting pipe work to assist in the board’s location and installation.
