Domestic Hot Water Tank

Heat pumps Residential

The Power World (domestic hot water) hygiene boiler uses high-quality stainless steel as the inner tank, which effectively prevents rust and corrosion. This provides good heat insulation, improves health and safety, and guarantees a long lifespan.

A built-in stainless steel corrugated pipe separates the drinking water from the heating water and simultaneously functions as a powerful heat exchanger. This combines the advantages of a buffer tank with those of a flow heater. The fresh (tap) water only flows through the stainless steel corrugated pipe when there is a need for (hot) tap water, without disrupting the stratification of the heating water. This achieves very low energy consumption and guarantees legionella safe drinking water. A legionella protection program in the scheme is therefore no longer necessary.

Closed and pressure-bearing design, running with total water, supplying hot water by the pressure of tap water, constant pressure, and constant temperature of the water outlet, more comfortable to use.

Can be connected to heating equipment such as boilers and heat pumps to store hot water for occasional use.

Equipped with a water return port, connected to a water return device, the cold water can be heated instantly, which is highly comfortable and saves water for users.

Equipped with a one-way safety valve and negative pressure safety valve, which can effectively protect the safe operation of the water tank.

The strong anode rod is standard, which can effectively prevent corrosion and prolong the service life of the water tank.

Adopts floor-mounted installation method, which is easy to install and maintain, and suitable for various environments.
