CHARACTERISTICS AND REQUESTS

ABOUT YOUR GAS HEAT PUMP AIR CONDITIONER

The gas heat pump air conditioner (GHP) uses gas as the fuel to drive the compressor.

As it uses gas engine, there are various characteristics.

•As the unit does not easily frost, defrosting operations are infrequent even on very cold days, allowing the unit to provide stable and continuous heating.

•As the electric power consumption is about 1 kW, this leads to be less received power equipment.

However, as with a car engine, periodical inspections by a specialist are for efficient use needed for a comfortable operation. Please make sure you have these periodical inspections.

PLEASE ENSURE YOU SIGN UP FOR A REGULAR CHECK UP CONTRACT
