The WWK 300 electronic SOL proves that first-class efficiency can be extremely quiet. In addition to the highly efficient heat pump, the excellently insulated, integrated domestic hot water tank ensures a high level of hot water comfort. The high-quality design is matched by the convenient operation via the LC display. All important information can be called up at the touch of a button, such as the currently available amount of +40 °C warm mixed water. Even more efficient with solar support. Every WWK electronic can be connected to a photovoltaic system or an external signal generator (selected inverter required). In this SOL variant, a solar thermal system or another external heat generator (such as an existing heating system) can also be connected. Product features: Hot water heat pump Compact series for recirculation mode 291 liter storage volume SOL variant also with integrated heat exchanger for connecting an external heat generator (e.g. solar thermal energy or an existing heating system) Achieves the highest possible energy efficiency A+ Hygienic hot water temperatures of up to 65 °C are only possible in efficient heat pump operation SmartGrid - pioneering technology Maximum safety and cost savings thanks to maintenance-free external current anode Technical data: Average heating output (A15 / W10-55): 1.6 kW Height: 1905 mm Diameter: 690 mm Weight: 156 kg Energy efficiency class for hot water preparation (indoor air), load profile XL: A+ Operating limit of heat source min. / max.: +6/+42 °C Nominal content: 291 l Heat exchanger area: 1.3 m² Hot water temperature with heat pump max.: 65 °C Nominal hot water temperature (EN 16147): 55 °C Nominal load profile (EN16147): XL Maximum usable nominal hot water quantity 40 °C (EN 16147 / A15): 387 l Average heat output (EN 16147 / A15): 1.54 kW Heating time (EN 16147 / A15): 9.60 h COP (EN 16147 / A15): 3.30 COP (EN 16147 / A20): 3.51 COP at A15/W15-55 (EN 255): 3.82 COP at A15/W15-45 (EN 255): 4.22 Additional heating input: 1.5 kW Sound power level (EN 12102): 60 dB(A) Average sound pressure level at 1 m free field distance: 45 dB(A) Mains connection: 1/N/PE 220-240 V 50/60 Hz
