SQUARE Heat Interface Unit (HIU)

The SQUARE HIU uses the latest electronic stepper motor controls to provide both DHW and central heating, using two plate heat exchangers.

Although capable of providing more, the central heating heat exchanger is designed to deliver very low central heating loads significantly under 5kW while maintaining very low primary return temperatures. In addition the twin wall DHW heat exchanger provides complete protection from cross contamination in the case of a plate failure, complying to the most stringent European regulations.

Overall dimensions are only 665mm (W) x 665mm (H) x 310mm (D) with less than 2W standing heat losses.
