The heat pump central hot water solution for families is very popular today and used for many projects such as villas, castles, buildings, resort apartments...

What is a central water heater (heat pump)?

The central hot water system is a system of water heaters using heating wires and sensor relays. It operates thanks to a control valve and a safety switch. Unlike the hot and cold water heaters that we often see, the central hot water system does not need a tank and can heat water in minutes. With such an operating principle, the central hot water system is considered very simple and convenient. It is a solution to avoid wasting energy thoroughly, causing little harm to the environment. Thanks to that, this technology has been widely applied today.

Outstanding advantages of Kahawa

Heat pump structure 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

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 loop.

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.

Kahawa heatpump operating principle

Why should you use Kahawa 250 liter family heat pump?

• Just one device can provide hot water for the whole family ==> reduce equipment investment costs.
• Heat water in just a few minutes ==> save a lot of time to do other things.
• Using heat from the outside environment to heat water, not directly using electricity ==> saving costs and limiting electricity leakage, very environmentally friendly.
• At the water outlet valve there will be an automatic water mixing device when the water is too hot ==>> to limit the risk of burns in apartments with the elderly and children.
• Kahawa's 250 liter household heat pump water heater has a large capacity, meeting the hot water needs of large families. You have enough hot water for daily activities such as bathing, washing dishes, and laundry without worrying about water shortage.
