Kahawa central hot water systems are installed on apartment balconies or hotel roofs to provide continuous and safe hot water, saving electricity and modern amenities. With many outstanding advantages, bringing users many conveniences and safety in saving electricity, many families and hotels have installed Heat Pump central water heater systems. However, the market makes it difficult for customers to choose reputable products, let Kahawa Vietnam provide the best service.
Kahawa central water heater is a system with a working principle similar to an air conditioning system. Unlike the hot and cold water heaters we often see, the central water heater system does not need a tank, can heat water quickly after a few minutes with a large capacity (>500l / day).
With such operating principle, the central hot water system is considered simple and convenient. It is a solution to avoid wasting energy resources thoroughly and causing little harm to the environment. Thanks to that, this technology has been and is being increasingly widely applied today.
Heat pump central water heater consists of 4 main parts: dryer, compressor, condenser and fan, pump connected together to form a closed loop. With the above operating principle, heat pump central water heater takes advantage of natural heat sources to create hot water, saving up to 80% of power consumption, bringing much higher economic efficiency than traditional heating methods from electricity, gas or oil...

The structure of a heat pump central water heater has 4 main parts.
– Kahawa heat exchanger (Anti-tangle conduit heat exchange technology, higher heat generation efficiency than 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 water heaters are used for heating within the family. On a larger scale, in units that are not directly involved in production, people use reversible central water heaters for heating in winter and cooling in summer.
How central water heater 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 loop.
Central hot water system is an energy-saving solution, safe for users, no dangerous electrical problems. The system can operate for a long time, has high durability, is a reliable product of many investors today.

Flat panel solar collector combined with central water heater
Flat plate solar water heater is a product that uses solar energy to heat water through heat absorption by flat collector plates. Flat plate water heater is the product line that is considered the most advanced today compared to popular lines on the market. The outstanding features of the product to easily distinguish it from other product lines are:
- Neat and aesthetic flat panel design
- Withstand high water pressure (tempered glass)
- Long lasting – low maintenance costs
- The absorber panel is manufactured in Japan on Japan's leading technology line - the product meets Solar Kemark standards - with a Tinox blue titanium coating that has an absorption efficiency of up to 96%.
- The glass used for the solar collector flat panel is a specialized tempered glass (Low-iron Prismatic/matt Tempered Solar Glass) - which helps to achieve high heat absorption efficiency and is very safe for installers and users.
- High absorption efficiency of 96% sunlight
- The collector frame is made of aluminum alloy manufactured by a Japanese factory according to JIS H4000-2015 standard with an anodized coating - which has anti-corrosion and anti-oxidation functions even when installed in coastal areas or on boats.

Application of central water heater - heat pump in life
The best heat pump central water heater is widely used in civil works, villas, motels, hotels, resorts, golf courses, schools, hospitals, factories... Heat pump central water heater with intelligent control system creates hot water according to the required temperature - operates according to the set time frame, absolutely safe for users due to indirect heating. Heat pump central water heater is designed with a luxurious and modern style suitable for all installation locations of the project. In addition, Heat pump central water heater can also be combined with solar hot water system, this is the most optimal energy solution to meet all usage needs.
Comparing using a heat pump with using a water heater, a villa with 5 bathrooms (bathrooms) when using a water heater heated by direct electric resistance will need 5 water heaters (each heater has an electric capacity of 2.5 KW x 5 heaters = 12 KW when in use + 5 switches, 5 circuit breakers, electric cables + installation labor). When using a heat pump (total hot water), only 1 heat pump is needed installed on the roof with an electric capacity of 1.2 KW when using a heat pump, the electric capacity is much less than using a water heater and is safe (because the heat pump operates indirectly like an air conditioner), in terms of convenience when using a heat pump, hot water is always available and provides a large amount of hot water to meet all usage needs.
So using a heat pump to heat the oven is much more energy-saving and safe than using a direct electric water heater.
- Heatpump is imported by Kahawa Vietnam (with import certificate CO, CQ)
- Heat exchange coefficient, fast heating efficiency and high COP
- Integrated Wifi connection control via phone
- The heat exchanger is coated with a protective layer against salt corrosion and acidic environments (no oxidation or rust).
- The machine has an auxiliary resistor (reserve it during maintenance and repair to increase the temperature to kill bacteria and use as a backup when the machine has a problem) other machines do not have.
- Insulated tank with enameled steel inner core retains heat better and is antibacterial.
- The middle layer has a thick layer of Polynethane insulation to keep the heat in.
- The outer shell of the electrostatic painted steel tank is safer. Panasonic compressor is a Japanese brand and Wilo circulation pump is a German brand.
- The fan motor and heat exchanger protection section has thick steel mesh.
- Kahawa's outstanding technology is the tube heat exchanger which brings high efficiency in heat exchange and saves energy, preventing flow turbulence.

Comparison when using heat pump with using water heater A hotel with 60 rooms has 60 toilets (bathrooms) when using water heaters heated by direct electric resistance will need 60 water heaters (each heater has an electric capacity of 2.5 KW x 60 heaters = 150 KW when used + 60 switches, 60 atomat, electric cable for 60 water heaters). When using a heat pump (total hot water), only 1 heat pump is needed installed on the roof with an electric capacity of 4-6 KW when using a heat pump, the electric capacity is much less than using a water heater and is safe (because the heat pump operates indirectly like an air conditioner), in terms of convenience when using a heat pump, hot water is always available and provides a large amount of hot water to meet all usage needs.
Thus, using heat pump hot water solution saves investment costs in materials, installation labor, saves energy and is safe and meets the need for a large amount of hot water and is safe and convenient.
