Why PAC Heat Recovery Water Heater?

PAC Heat Recovery Water Heater generates hot water by using waste heat from air conditioning. Unlike typical water heaters that uses electricity or gas to heat your water, our system gives you hot water for free. In addition to free hot water, the air conditioner connected with the PAC system will reduce the electricity consumption by exchanging heat from the refrigerant and water ventilation through a condenser. The result is that your overall power consumption goes down by 30%. It also helps to extend the life time of the compressor unit.


PAC Heat Recovery Water Heater generates hot water from any split type air conditioner. Our high quality pressure tank with 2 layers of 2 mm thick walls, with high quality insulations, can store hot water for up to three days. The double walled construction also prevents heat transfer to the surface of the tank, that may be hazardous to the user.
