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

Reason of selection

  • We have been using GHP since we start the business in 1995. After long-term use, we considered to replace GHP.
    We initially considered to adopt EHP during the 1st retrofitting phase of project, but due to cost increase from higher demand and EHP installation,
    we selected GHP as the infrastructure was already there.
  • As for the manufacturer of GHP, we selected Aisin since the maintenance support is reliable.
    For the second retrofitting phase, we selected Aisin GHP again for the same reason.

Impression

  • It was difficult to satisfy both requirements of day-care room and kitchen as they shared the same air conditioning system.
    However, the maintenance company; Taihei engineering separated the system during the second retrofitting phase.
    Although an additional outdoor unit was required, now we can provide desirable air conditioning for each space.
    We are happy to reduce the gas consumption by 17% after installing E1 series    .
