The European Commission has determined requirements in the directive 2009/125/EG for the energy consumption of products regarding ecological design. The goal of this directive is to realise a considerable saving on the energy consumption and therewith a reduction of CO2 emissions. This has resulted in the establishment of regulation 1253/2014, which imposes requirements for the ecological design of ventilation units. These requirements have come into force by January 1st 2016 and will be further defined by January 1st 2018. Ecodesign The new regulation 1253/2014 for ventilation products...

The new regulation is applicable to the following ventilation units: - Residential ventilation units (RVU): ventilation units with a maximum air flow of not more than 250m3/h or with a maximum air flow between 250 and 1000 m3/h, which according to the producer are exclusively intended for residential ventilation. - Non-residential ventilation units (NRVU): ventilation units with a maximum air flow of more than 250 m3/h, or with a maximum air flow of the ventilation unit between 250 and 1000 m3/h, which according to the producer are not exclusively intended for residential ventilation.

Environmentally friendly heating with the GS+ Mark manufactures a gas-fired, highperformance air heater with an axial fan. This condensing equipment provides efficiency greater than 106% (lower value). Heat is generated via a modulating premixburner which results in very low gas consumption. The GS+ is operated using an Optitherm+ clock thermostat or an Interface+ module that allows a connection with the BMS (building management system) via Modbus or a 0-10V contact. The Optitherm+ also makes it possible to control the GS+ units remotely with an app for mobile phone and tablet (available...
