DHW and buffer tank for heat pumps

KAISAI Eco Home is a specially designed, innovative DHW and buffer tank for heat pumps, which combines both a domestic hot water tank and a buffer tank in a single housing.

The design of the device saves space while maintaining functionality and the necessary operating parameters. The Eco Home water heating tank fits perfectly into any type of installation, both newly designed and modernised, guaranteeing reliability, simple installation and ergonomic space.

The materials used to manufacture the DHW and buffer tanks (DHW tank with coil and buffer tank – SUS316 stainless steel, 50 mm polyurethane insulation) minimise heat loss and ensure durability and many years of operation. The connection pipes for the installation and heat pump are located on both sides of the tank, ensuring convenient and simple installation.

In addition, the domestic hot water tank has been upgraded with a 3 kW electric heater as standard equipment.

DHW and buffer tanks for heat pumps are often an underestimated but important component of modern and environmentally friendly heating systems. Their role and functions may vary depending on the specifics and size of a given heating installation. Although the purchase of a water heating tank increases the initial investment costs, its use brings a number of benefits that can offset the expenses incurred.

DHW and buffer tank – advantages:
The buffer tank ensures minimum water volume and water flow of heating through the heat pump regardless of the operating conditions of the system. In addition, it reduces the frequency of heat pump activation, which translates into lower electricity bills and extends the service life of the device. As a result, its total operating time per year is also reduced, which also contributes to longer pump operation.

Interestingly, with the right buffer tank capacity, you can significantly reduce your electricity costs by using two tariffs (a more expensive daytime tariff and a cheaper night-time tariff). The long-term savings resulting from investing in a water heating tank are therefore undeniable.
