The STIEBEL ELTRON WWK 301 electronic heat pump water heater demonstrates the flexibility of this type of boiler. Equipped with air ducts, the heat pump water heater can draw in outside air or heat released from a neighboring room. Moreover, the ducts can be installed horizontally or vertically, depending on the conditions in the installation space.
Investing for the Future
The device also impresses with its features: it achieves the highest possible energy efficiency and thereby delivers high hygienic hot water temperatures. The simple combination of the heat pump with a solar panel installation makes the operation even more resource-efficient, as the self-generated electricity can be used to heat the tap water.
