The direct heat interface unit is specifically designed for only radiator heating and instantaneous DHW preparation with thermostatic control.

It has all necessary components (e.g. valves, heat exchangers, pipes, fittings and connections) to deliver convenient and efficient DHW and heating.

Versatile’s HIU’s offer the very best in terms of performance, longevity and price. The HIU offering is the ultimate package for designers, installers and consumers.

The direct heat interface unit has 3 output powers based on the number of plates of its heat exchanger: 33, 45, or 70kW.

• Dual differential pressure control valve that offers stable and continuous supply of heating and hot water.
• Latest SWEP plate heat exchanger offering exceptional performance.
• Heating thermostatic control valves ensures an accurate temperature across all heating circuits or underfloor heating manifolds
• Water arrestor to avoid noise, vibration and water hammer in the system.
• EPP thermal casing to ensure minimum heat losses and maximum heat efficiency.
