• VRV IV Heat Recovery Hot Water system


The energy-efficient system recovers waste heat as energy to heat hot water.

Waste heat from air conditioning (which usually released into the ambience) is recovered to heat water.

The Serpentine Heat Exchanger Unit recovers heat.

Increased energy efficiency of the outdoor unit

The waste heat from air conditioning is transferred to heat water.
This mechanism reduces the amount of heat processed by the outdoor unit, resulting in better operation efficiency.

Reducing short circuits

The temperature of exhaust heat from the outdoor unit is lower, minimising in ambient temperature increase. In the event of a short circuit, capacity reduction is minimised.

Innovative and reliable system

Example on usage of VRV IV Heat Recovery Hot Water System for residence

In a sample family model of 3 adults and 3 children, the waste heat generated by air conditioning is sufficient to supply hot water for everybody’s showers.

Water-heating load Tank capacity: 200 L
Boiling temperature: 25°C to 60°C (tap water)

Amount of hot water per person per time (standard): 50 L/shower (39°C) (water dispensed: 10 L/min.; shower time: 5 min./shower)
Amount of water required in tank to dispense 39°C hot water

Comparison between VRV IV Heat Recovery Hot Water System and electric heater

Because waste heat is used to heat water, annual electricity consumption can be reduced approximately 94% compared with consumption for separate operation of air conditioning and an electric water heater.

VRV IV Heat Recovery Hot Water Controller


Convertible Remote Controller
Main Remote Control & Sub Remote Controller are both convertible and interchangeable.

By default, this would be activated every Monday morning at 2am, heating storage water up to 60°C for 10 minutes.

Vacation Mode
This disable all other functions, except for anti-bacterial mode.

Auto Restart
When power supply is restored after a failure, the system would revert to the last operational function.

Safety-Error Code
If thermistors or communication line are faulty, as a safety precaution, operation of the electric heater is disabled.
