Heat pump- what is heat pump?
Heat pump Kahawa is a leading brand in the heat pump industry with superior quality and technology manufactured for the Japanese and exported to the EU and ASEAN markets. Heat pump Kahawa is an indirect water heater with high heating efficiency, saving electricity instead of direct-fired water heaters that are both energy-consuming and unsafe. The Kahawa water heater will provide a large amount of hot water for many uses and is safe, energy-saving and convenient. Heat pumps are installed on the attic or roof of villas, castles or roofs of hotel buildings. Kahawa Vietnam is the representative of the company in Vietnam, importing genuine original packaging, genuine warranty and maintenance with full import certificates to introduce products, distribute and sell and after-sales in the Vietnamese market.
Heat pump structure has 4 main parts
– Kahawa’s heat exchanger is superior to other brands (The heat exchange technology of the conduit pipe prevents the flow of the pipe, the heat generation efficiency is higher than the conduit technology in the tank of other brands)
– Kahawa’s compressor uses the world’s leading brand compressors such as (Copeland, Panasonic, Hitachi, DC Inverter technology, the compressor runs smoothly and durably, saves electricity, achieving high durability and efficiency in the heat pump industry)
– Kahawa’s condenser is thick and coated with anti-corrosion layer for salty and acidic environments, preventing rust
– Kahawa’s expansion valve uses a 4-way valve for efficiency, durability, safety and automatic defrosting

How heat pump works
Heat pump heat pump also known as "central hot water machine" 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 thermal 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.
Central hot water system is an energy-saving solution, safe for users, without dangerous electrical problems. The system can be Long-term operation, high durability, is a reliable product of many investors today.

Compare the cost and electricity capacity when using heat pump vs water heater for family
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 tank has an electric capacity of 2.5 KW x 5 tanks = 12 KW when in use + 5 switches, 5 atomats, 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.

Comparison of investment costs and electricity costs when using a heat pump versus a water heater for a hotel
A 30-room hotel with 60 bathrooms (bathrooms) when using a direct electric resistance heating water heater will need 60 water heaters (each heater has an electric capacity of 2.5 KW x 30 heaters = 75 KW when in use + 30 switches, 30 circuit breakers, electric cables for 30 water heaters). When using a heat pump (total hot water), only 1 heat pump installed on the roof with an electric capacity of 4-6 KW is needed. 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 a large amount of hot water is provided 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.
