Domestic ground source heat pump. Identical in design to the SIH ME range, the unit provides flow temperatures up to 58°C making it an ideal domestic heating solution.

Where space saving is an issue the unit can be combined with a 200 L domestic hot water cylinder, which fits neatly below the heat pump unit.

Features and benefits:

  • Nominal heating capabilities of 14 kW.
  • Variable heating water flow temperatures from 35–70°C.
  • WPM 2007 heat pump manager with removable control panel.
  • Electronic soft start control reduces starting current loads.
  • Suitable for use with underfloor heating, Dimplex SmartRad fan convectors or conventional radiator systems and to produce domestic hot water.
  • Can be used as the sole heating source or in 'bivalent' mode in combination with an existing heating system.
  • CE marked.
