300 liter family heat pump (1.5HP) is suitable for families of 5-8 members (2 to 9-storey prison). The heat pump is manufactured on a modern production line and meets Japanese standards. The machine uses heat pump technology so it has many advantages such as: low cost, safe without electric shock, energy saving, flexible installation, easy to use, suitable for apartments, villas, townhouses...

Introducing 300 liter family heat pump central hot water solution

Hot water is an indispensable need for households in Vietnam. Using hot water for activities such as bathing, washing clothes, and supplying equipment such as dishwashers, washing machines is very convenient, increasing the efficiency of the equipment. Imagine waiting for hot water to bathe or wash dishes in the cold of 10°C in winter. That is why the central water heater becomes a perfect solution.

Kahawa's central hot water system is the perfect solution for you, providing continuous hot water without waiting time. Using heat pump technology, this system saves energy effectively. The 300 liter hot water tank capacity ensures enough hot water for 3 bathrooms and many other activities in the family.

The structure of a heat pump has 4 main parts.

– Kahawa heat exchanger (Heat exchange technology with anti-flow conduit pipes has higher heat generation efficiency than the conduit technology in the tank of other brands)

– Kahawa compressors use the world's leading brand compressors such as (Copeland, Panasonic, Hitachi with advanced technology achieving high durability and efficiency in the heat pump industry)

– Kahawa condenser has high density and is coated with anti-corrosion layer to prevent rust and salty and acidic environments.

– Kahawa throttle valve uses 4-way valve for efficiency, durability, safety and defrosting

Central hot water advantages

Kahawa heat pump structure

• Heat pump is imported in its entirety with full import certificate.
• The tank is made of pressure-resistant, antibacterial, heat-retaining enamel-coated steel (the enamel layer ensures heat retention and antibacterial properties).
• 50mm thick polyurethane insulation layer in the middle
• Powder coated steel shell (Safe for equipment and users)
• The hot water tank has an integrated backup resistor that automatically turns on periodically to disinfect the system when the heat exchanger is being maintained or when there is a problem with the condenser, hot water still runs. 
• Heat exchanger condenser with safe electrostatic painted steel shell
• Heat exchanger with anti-corrosion and anti-rust coating for salty or acidic environments
• Wilo-Germany brand circulation pump runs smoothly and durably
• Panasonic Japan Compressor
• High heating coefficient high COP heats water quickly
• Production system on modern Japanese technology line ensures EU export standards
• Kahawa Heatpump central water heater is a smart choice for everyone and every family.
• Outstanding Japanese tube-to-tube exchange technology provides high heat exchange efficiency and anti-turbulence compared to other brands.

How heat pump works

Heat pump, also known as "central water heater", is a machine that uses the principle of thermodynamics including 4 cycles:

– Evaporation stage (the heat carrier absorbs the ambient air temperature and heats up, evaporating into a warm gaseous heat carrier, the air loses heat and condenses into water on the evaporator.

– The compressor heats up the heatsink when a compressor force is applied to it.

– Condensing stage (the heat carrier when leaving the compressor is heated up to 100 degrees Celsius and enters the condenser, where it will transfer heat to the water to heat it up to the required temperature of 55 to 65 degrees Celsius and is led to the insulation tank to keep the temperature. 

– Expansion valve (after the heat carrier transfers heat to the hot water, it continues to pass through the expansion valve to form a closed cycle.

Therefore, heat pump water heaters are the optimal solution to save energy for hot water needs of families or production facilities in hot and humid climates, such as Vietnam.
