LaZer. Saving the equivalent energy of almost 200 houses & the CO2 Emissions of over 1000 cars per year

Although Zehnder developed the steel tube radiator over eight decades ago, it is still actively working on processes to make its classic designs even more environmentally friendly. 

An excellent example of this is the updating of the Charleston welding process to LaZer made. This innovative laser welding method for the production of sectional radiators is setting new standards for quality and technology in terms of precision, quality, functionality and sustainability. Thanks to LaZer made, manufacturing can be more precise than ever before – all without residues inside the radiator or offsets on its surfaces. This makes for an even more attractive appearance and optimised radiator operation. 

In addition to these impressive improvements an 9% reduction in the cumulative energy required and CO2 emitted was achieved, equivalent to the annual consumption of almost 200 houses & the annual CO2 emissions or over 1000 cars.

A Zmart solution in Sustainability

Outstanding reliability

Long-term, carefree heating comfort.

Zehnder Zmart models meet the highest requirements in terms of quality, durability and sustainability. That is why Zehnder provides a 15-year manufacturer warranty for the components as well as a 5-year manufacturer warranty for the thermostatic control and valve insert. Even when installed in an existing system.

Ecology

Heating with a clear conscience.

Zehnder Zmart makes a strong impression with unbeatable environmental credentials: With the excellent heat output, Zehnder Zmart is extremely effective and its excellent environmental credentials make it a pioneer when it comes to sustainability.

An independent assessment shows that the environmental impact of manufacturing, transportation, use and recycling is 40% lower when compared to standard steel radiators. The CO2 footprint that is also 21% lower compared to that of standard steel radiators. Maximum ecological compatibility is ensured even during packaging. Zehnder breaks new ground not only in the selection of materials and design, but also in production, primarily supported by development partners and suppliers from the automotive sector.

The ComfoAir Q sets a new standard in both ventilation performance & sustainability.

Ventilation heating costs reduced by 38%: by the use of a larger heat exchanger with optimised air guides that distribute air more efficiently and eliminate the need for a separate bypass.

Remaining heating load for ventilation

Electricity consumption reduced by over 10%: through new fan & pre-heater technology which gives a higher level of comfort providing fresh air at a constant temperature almost silently

Consistent efficient performance during the entire lifespan: through the use of EPP (Expanded Polypropylene), a proven technology in Zehnder products, shrinkage which leads to a deterioration in performance is avoided. Additionally the innovative use of sensors and user friendly interfaces avoids incorrect setting and ensures optimum performance.

Achieving a new standard of Energy efficiency and Comfort in China, with the first commercial building to achieve passive house certification

Air pollution and the efficient use of energy are issues of growing concern in China, where buildings account for 30% of total energy consumption. The Chinese government has therefore begun to promote energy efficient building which is a key strength of Zehnder, whose heating, cooling and ventilation system including all controls, allowed the first ever passive house certification for a commercial building to be achieved in China.

Zehnder supplied and installed 2 highly efficient ventilation systems (3000m3/h and 9000m3/h) with both heat and entropy converters, as well as a geothermal heat pump, underfloor heating and cooling; and ceiling panels for supplementary cooling.

Fresh and clean air is provided 24 hours a day with a comfortable room temperature of between 22 and 26°C. The annual energy requirement for heating is only 15KWh/m2.

Energy consumption is continuously monitored and the whole system can be adjusted using a smart phone app.

Paul: A Zehnder Subsidiary dedicated to Sustainability

The Zehnder subsidiary PAUL exemplifies our dedication to providing sustainable products in a sustainable way. The efficient use of energy; recovering over 90% of heat and or 60% moisture, whilst ensuring fresh and clean air is PAUL’s very successful business model based on sustainability. Products are produced in the first ever passive office building in East Germany which has an annual energy consumption for heating of less than 15 KWh/m² per year, about 10% of the average consumption of a domestic household (source http://shrinkthatfootprint.com).

Our innovative solutions give us the ability to provide energy recovery for both new buildings and renovation projects
