1 RENEWABLES DHW HEAT PUMPS Energy you can recycle Intelligent technology which utilises free energy from waste heat or the outdoor air to generate hot water for the entire household

2 STIEBEL ELTRON is full of energy As a family company driven by innovation, throughout product development and manufacture we maintain a clear focus on environmentally responsible, efficient and convenient building services for your home. Because we're full of energy and ready to shape the future! The future belongs to environmentally responsible and efficient building services. Since 1924 we have been developing highly efficient products and maintain a clear focus on electricity as our primary energy source. Electricity which nowadays is increasingly obtained from renewables. We rely on over 3100 employees around the world and their expertise at every stage of development from the initial design right through to the manufacture of the final product. The result efficient and innovative solutions for domestic hot water, heat, ventilation and cooling. With our extensive product range, we always have the right option to prepare your home for the demands of the future today. At our head office in Holzminden, Germany, we have also established a clear focus on green technology with the Energy Campus, our flagship project for sustainable construction which makes careful use of resources. This training and communication centre brings together high quality architecture and communication technology. And as a Plus Energy building, it generates more energy than it consumes. This is in keeping with our brand promise "Full of energy" and creates a space where the spirit of STIEBEL ELTRON can be experienced both in theory and practice.

3 DHW heat pumps Electricity the energy source of the future Renewable energies will become the norm for the future of energy supply as more and more people recognise the benefits of green and self-generated power from renewable sources. The goal of the energy transition is independence from fossil fuels Fossil fuels are in decline on the electricity market too harmful to the climate and ever more scarce. Nowadays, alternative energies using the sun, wind and water are being used to generate green power. So it is only logical to act in good time to convert the largest energy consumer in your home the heating system to these futureproof forms of energy. As nearly 80 % of energy consumed in the home is used for heating and hot water, this makes perfect sense. So there is plenty of scope for implementing the energy transition in your own home.

4 If you don t need something, it s a good idea to exchange it for something else rather than just throw it away. If you re smart about it, you can even exchange heat, such as surplus heat in the boiler room, to heat cold water. Giving you virtually free hot water.

5 DHW heat pumps Get easily accessible and affordable heat from the basement High grade DHW heat pumps from STIEBEL ELTRON utilise free environmental energy for DHW heating and thereby provide an efficient, environmentally responsible solution for year-round generation of hot water using renewable energy. EXCELLENT ENERGY EFFICIENCY Our DHW heat pumps achieve the highest possible energy efficiency class: A+. ENERGIE- EFFIZIENZ A+ Where DHW heating from renewable sources is concerned, DHW heat pumps offer a quick and convenient solution. Basements in particular are often heated passively and unintentionally, whether by a boiler or by electrical appliances that give off a lot of heat. Rather than allowing it to go to waste, DHW heat pumps reclaim this energy. Up to 70 % of the energy required for DHW heating can be taken from recirculation air. An entire detached or two-family house can be supplied with domestic hot water by feeding the yielded heat into the integral cylinder.

7 WWK HIGHLY FLEXIBLE 221/301 (SOL) The WWK 221/301 series combines all the benefits of the WWK 200/300 series, but also features an air duct for the intake of outdoor air or waste heat from an adjacent room. DHW heat pumps Ready for whatever space is available The air intake and discharge ducts can be mounted horizontally and/ or vertically (the accessories for vertical mounting are available as an option). This allows maximum flexibility when it comes to installation and layout in the installation room. Futureproof investment The equipment includes a maintenance-free impressed current anode, making regular anode tests unnecessary and saving on costs. An integral contact input is also included as standard to allow for combination with a photovoltaic system *, for example, to increase on-site consumption. Benefits for your home High degree of flexibility regarding siting and installation Achieves the highest possible energy efficiency: A+ Hygienic DHW temperatures up to 65 C possible in efficient heat pump mode alone SmartGrid Ready PREMIUM Model WWK 221 WWK 301 WWK 301 SOL DHW heating energy efficiency class (load profile). indoor air A+ (L) A+ (XL) A+ (XL) Energy efficiency class for DHW heating (load profile). outdoor air A+ (L) A+ (XL) A+ (XL) Rated capacity l Maximum DHW temperature with heat pump C Max. mixed water volume 40 C l Heat source min./max. application limits C -8/+35-8/+42-8/+42 Nominal DHW temperature (EN 16147) C Nominal load profile (EN16147) L XL XL Maximum available nominal DHW volume at 40 C (EN / A20) l COP (EN / A20) Sound power level. indoor. with 4 m air duct (EN 12102) db(a) Average indoor sound pressure level at 1 m distance. free field with 4 m air duct db(a) Height x diameter mm 1545 x x x 690 * Selected inverter required.
