The monolithic heat pump system is a central hot water system using heat pump technology that is currently popular and widely used because of its superiority such as saving 70% of electricity compared to electric water heaters, high electrical safety, providing hot water with large demand, durable and stable.

With a central hot water system with a return line design - there is always hot water at the tap when needed without waiting time. Only 1 device is needed to provide hot water for the entire building.

The heat pump is a machine with a structure consisting of 4 main devices (Compressor, Condenser, heat exchanger between air and heat carrier, expansion valve) operating according to the principle of thermodynamics with the purpose of transporting heat from one environment to another to heat the water stored in the thermal insulation tank (Structure and operating principle are similar to air conditioners)

The structure of a heat pump has 4 main parts.

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

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

– Kahawa condenser has a thick density and is coated with anti-corrosion layer for salty and acidic environments, preventing rust

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

Structure of Kahawa heat pump

• Heat pump heatpump is imported in its entirety with full import certificate
• Insulated tank body is made of pressure-resistant antibacterial enamel-coated steel (enamel coating ensures heat retention and antibacterial)
• 50mm thick polyurethane insulation layer in the middle
• Powder-coated steel shell (Safe for equipment and users)
• Hot water tank with built-in backup resistor that automatically turns on to disinfect the system when maintaining the heat exchanger or when the heat exchanger has a problem, hot water still runs
• Heat exchanger heat exchanger shell is made of safe powder-coated steel
• Heat exchanger is coated with anti-corrosion and anti-rust layer for salty or acidic environments
• Wilo-Germany brand circulation pump runs smoothly and durably

• Central water heater heat pump Heatpump Kahawa is a smart choice for everyone and every family. Outstanding Japanese exchange technology with sleeves and tubes brings high heat exchange efficiency and anti-turbulence compared to other brands.

How heat pump works

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

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

- Compressor heats up the heat carrier, the heat carrier increases rapidly when a compressor force is applied to it.

- Condensation stage (the heat carrier when leaving the compressor is heated up to 100 degrees Celsius, enters the condenser, where it transfers heat to the water to heat up to the required temperature of 55 to 65 degrees Celsius, and is led to the insulation tank to keep the heat

- Throttle valve (after the heat carrier transfers heat to the hot water, it continues to pass through the throttle valve to form a closed loop.

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

A heat pump water heater works on the same principle as an air conditioner or a refrigerator. It absorbs heat from the air and converts it into hot water. Therefore, it is also called an air source heat pump. It runs on electricity but is more efficient than a conventional electric water heater.

High efficiency micro channel heat exchanger

Larger heat exchange area, Better heat transfer efficiency and more durable performance.

The system efficiency coefficient can reach 4.25 or even higher.

No contact with water in the water tank, so the heat exchanger is not at risk of corrosion, scaling, leakage, etc.

High efficiency compressor

As an internationally renowned brand of dedicated compressor for heat pumps, it is more reliable in system matching and operates more smoothly.

Smart defrost

With intelligent defrosting design, it can revolutionary solve the blockages of heat exchangers in cold winter such as freezing and slow heating, etc., allowing you to spend a more comfortable winter.

Smart and convenient touch control

Smart light display.

WIFI control.
