ENWarmth for your home Energy for lifeRoom heating, cooling and hot water using energy from the airRenewables Air source heat pumps06 | 2023

We love being at home and like things to be cosy. Green technology helps us to achieve this. The environment lends us a helping hand, too. Our heat pump draws in outdoor air and extracts the energy from it. We then use this for room heating, cooling and hot water.Comfort through technology

Giving the future a green lightTurning the tide ourselvesPower companies, politicians and society have been seeking viable alternatives to fossil fuels for a long time. Fossil fuels are exhaustible resources that pollute the environment. So why not simply tap into the heat contained in the sun, air, water and ground, and put it to use in your home?Renewables help to determine where our energy will come from in the future. More and more people are recognising the benets of green electricity for their homes. We too see electricity as the energy source of the future.You are bound to have some concerns about the energy efficiency of your house. Perhaps you would like to change to a futureproof energy supply. The largest energy consumer is your heating system: almost 80 % of the energy you consume goes into heating and hot water. There is therefore great potential for an energy transition in your home.02 | 03

Give yourself room to feel goodThe temperature affects how healthy and alert you are. The temperature range in which you constantly feel at your energetic best is narrow. Our top of the range air source heat pumps ensure a healthy room climate. If they are equipped with a cooling function, they even do so in summer as well. The appliance cools the heating water that ows through your underoor heating system, which lowers the room temperature. This increases your living comfort and vitality.Good reasons to enjoy your home comforts › Pleasant room temperatures all year round › Easier to relax and feel good › Greater vitality and alertness › Efficient heating and cooling in one appliance

Your air source heat pump from STIEBEL ELTRON takes energy from the ambient air and converts it into usable heat for your home, even at icy temperatures of down to minus 25 °C. Depending on the model and your preferences, the appliance is sited outdoors and saves on energy, but not on output. As a result, you won’t need a booster heater, even for high ow temperatures.Bring a breath of fresh air to your homeInverter technology – keeping a good balanceConventional heat pumps are either on or off. By contrast, our heat pumps with inverter technology are much more sophisticated. They expertly deliver precisely the output needed throughout your home for a comfortable indoor environment. This is not only more energy efficient, but also much less noisy. This is because the fan and compressor operate, on average, with a lower output and are consequently much quieter.Green technology with impressive properties › Output is continuously matched to your requirements › Higher efficiency in the partial load range › Very quiet › Top technology developed from many years of experience › Improved heating output and efficient energy consumptionUncomfortableUncomfortableComfortable room temperatureTarget valueInverter technology compared to conventional heat pumpsInverter Conventional heat pumps (on/off appliances)04 | 05
