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!

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 resour-ces. 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.

The future belongs to

environmentally responsible and

efficient building services.

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 fuelsFossil 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.

Air source heat pumps 02 | 03

“ For life, warmth is just as important as the air

we breathe. With the right technology it is just as

easy to harness. Our heat pump draws in outdoor

air and extracts its latent heat which we use for

central heating and domestic hot water. This even

works on cold days!”

›

›

› Continuous output matching

› Higher efficiency in the partial load range

› Very quiet

› Top technology – Made by STIEBEL ELTRON

› Wide application range down to –20 °C

› Improved efficiency and heating output

Metered output – full efficiencyIf cars only had two operating modes, i.e. full power or full braking, that would be neither comfortable nor efficient. Conventional heat pumps still operate just like that, as they are either on or off. This is where STIEBEL ELTRON air source heat pumps with inverter technology come into their own. They always deliver precisely the output that is currently required. Not only is this more energy efficient, it also reduces noise emmissions during spring and autumn. This is because the fan and compressor operate, on average, with a lower output and are consequently even more quiet than usual.

The air is full of energy

Outdoor air is supplied to the air source heat pump – installed either

indoors or outdoors – via flexible hoses and a quiet fan. A heat exchanger

extracts the latent energy from the air which is converted by the heat pump

into useful heat for your home. Even at icy temperatures as low as –20 °C,

the air source heat pump still operates efficiently and economically, all

the while impressing with its very high COP. Very high flow temperatures

can also still be achieved without backup from a booster heater.

Inverter Stop-start appliances


A heat pump to suit any demand profile

Air source heat pumps require little installation effort – and this makes

them more affordable to buy and more suitable to use when modernising

an existing heating system. In new build, too, this form of heating techno-

logy is highly desirable because of its efficiency, and it can be employed

in low energy houses, for example.

WPL A/AC/AS/ACSLow noise – high efficiencyLow operating noise is of critical relevance for outdoor installations – particularly when considering neighbours. The more quiet a heat pump is in operation, the smaller the clearance required to the nearest building. If required, a cascade of up to six heat pumps can be installed for heating and cooling larger living areas.

The WPL 15/20/25 A/AC air source heat pump, designed for installation outdoors, delivers first class efficiency, even at temperatures significantly below freezing. Its high flow temperatures make the supply of classic radiators possible.

COSY WARMTH FROM THE AIR, AT ANY TIME OF THE YEAR

Internet Service Gateway ISG | ISG plusWith the ISG, the heat pump system can be conveniently controlled from a PC, tablet or smartphone – via STIEBEL ELTRON SERVICEWELT, it can also be controlled while away from home. The optional extensions for KNX IP, Modbus IP and the link-up to the SMA Sunny Home Manager (EMI) provide for intelligent functional enhancement. The ISG plus can link your heat pump to variable power tariffs which may become available in the future, and to your photovoltaic system, to maximise the utilisation of power

Suitable accessories make STIEBEL ELTRON products capable of communicating – to create an intelligent energy management system. By networking heat pumps, storage technology and other building service appliances, the proportion of self-generated photovoltaic power consumed on site can be significantly raised, which in turn improves the overall level of energy efficiency.

generated on your roof. The SMA Sunny Home Manager works in tandem with the ISG to ensure truly intelligent energy management. It forecasts power-based demand and yields so as to best provide electrical consumers and cylinders with PV power. A wall mounted e-mobility charging station can also be integrated. The ISG forecasts demand for the required thermal energy, taking into account the thermal stores available in the building. With this efficient, cost effective approach, economical PV power can be stored thermally.

Highly functional and modularThe system components combine functionality, extendibility and ease of installation. At the same time, they feature the attractive new STIEBEL ELTRON design and have significantly improved connections for the electrical installation components.

The WPM heat pump manager is the brains of the system and is able to regulate numerous functions via its integral programming unit. For larger demand, the WPM with the WPE extension

controller can be extended with additional functions, to enable the integration of a woodburning stove via a universal differential controller, for example.

The FET touch wheel remote control enables the required room temperature to be controlled with great accuracy. The backlit graphic display shows the room temperature, relative humidity, time and outside temperature.
