Description

Range of heat interface units supplying instantaneous domestic hot water and indirect heating.


Features and benefits:

  • BESA registered.
  • Wide capacity range.
  • Primed domestic hot water control with 8°C set back (FI, R-FI, IV).
  • Integral differential pressure control.
  • Pressure absorber.
  • 20-year operating life.
  • Self-acting mechanical control.
  • Copper braised stainless steel Micro Plate™ Heat Exchanger.
  • Stainless steel pipes.
  • Fully insulated (FI, R-FI, IV).
  • Instantaneous shut off of heat network supply water through PHEX after tapping (reduces scaling of heat exchanger).
  • Strainers on heat network supply, heating return and cold water pipes.
