Hitachi Yutaki-M

Hitachi Yutaki-M


The Yutaki-M Monobloc air-to-water heat pump systems are available in capacities of 7.5kW or 14kW.

The Yutaki M can provide domestic hot water and heating and is therefore ideal boiler replacement technology in a suitably insulated home or it can be used alongside an existing heating solution.

It is a compact solution where a single unit is installed on the outside of the property, taking up no space inside.

  • Monobloc air-to-water heat pump system
  • Domestic hot water as well as heating – ideal boiler replacement technology
  • Screed drying function ideal for new builds
  • Weather Compensation Control
  • Generate water up to 60ºC
  • DHW Legionella Protection Program
