The patented G+R panel radiators heat in winter and cool resp. de-heat in summer – a cost-efficient alternative compared to insalubrious recirculating air conditioning systems. An asset not only for people susceptible to allergies or colds but as well for those preferring an innovative and ecological climate control system in order to guarantee a cosy feeling every time in the year. The heating and cooling systems, panel radiators, high-pressure radiators and low-temperature heating systems with flow temperatures of less than 40°C instead of 75°C do not only save a lot of energy but a lot of money, too.
