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.
Key Features:
- Heat pump water heater installed indoors
- Compact range for circulation operation
- Hygienic hot water temperatures up to 65°C possible with efficient heat pump operation
- Use of ambient heat for energy-efficient hot water preparation
- Maximum safety and cost savings through maintenance-free DC anode
- Whisper-quiet operation due to modern sound decoupling
- For supplying one or more tap points
- High user comfort through electronic control with LC display
- Connection to a photovoltaic system to increase self-consumption
- High hot water comfort with 302 l nominal capacity
- Compact range for circulation operation
- Hygienic hot water temperatures up to 65°C possible in pure heat pump operation
- Use of ambient heat for energy-efficient hot water preparation
- Maximum safety and cost savings
