2. Features
Energy-Efficient Water Heating System
DAIKIN’s WinterSpa series is a heat reclaim system which can reduce the electricity consumption of
a household. The design utilises the otherwise wasted condenser heat from air-conditioner system to
generate domestic hot water without extra energy consumption.
Flexible Connection to Air Conditioning System
The water tank can be connected from one to four condenser units, depending on the tank size.
Environmentally Friendly
By recycling the water energy of the air-conditioner, the DAIKIN WinterSpa actually helps to conserve
the environment.
Various Sizes - (DAIKIN WinterSpa Specifications)
The caters for individual needs and preferences, the DAIKIN WinterSpa water tank comes in various
sizes that can be installed indoor or outdoor, hidden or visible.
Easy Installation
There are vertical and horizontal water tanks. Installation is made easier in narrow and difficult space.
Weather Resistance
Built from highly durable material, the DAIKIN WinterSpa product is strong enough to withstand any
weather condition.
Optional Heating Element
If the air-conditional is not switch on, an optional backup electric coil can be installed in the tank to
provide unlimited hot water supply.
High Efficiency Heat Exchanger
The compact design of the 3-fold structure heat exchanger provides a large surface for better and more
efficient heat exchange.
The unique Hydrophilic slit fin has greatly improved the air flow and contact surfaces with the air, thus
boosting the cooling capacity.
Rotary Compressor
The ever popular rotary compressor is more energy efficient and has a higher output to weight ratio.
Self Diagnosis
This function is able to detect and diagnose any faults occurring in the system by blinking of the LED lights.
Simple and easy for troubleshooting.
