Effect after the retrofit with E1 series (example)

saved installation space
Compact E1 series design saved installation space.

Combined connection type outdoor unit,
  • Save energy as only 1 unit operates at times of low-power demand.
  • Longer equipment longevity via unit rotation.
  • Reduce Labor & material costs.

User's voice (This is an individual impression. It varies according to installation situation.)

Reason of selection

  • Existing GHP system was due for replacement.
  • We selected GHP due to limitation of electricity use and restricted air conditioning operation.
  • We selected Combined connection type outdoor unit as gas distributor advised us that multiple connection is energy efficient and environmentally friendly but also prolongs equipment longevity via unit rotation.
