With an impressive coefficient of performance (COP) of 3.7 (Atria Optimum 8 at A7/W35 according to EN14511) Thermia Atria Optimum delivers up to 75 % of energy savings. COP is a measure of heat pump efficiency and indicates the relationship between the amount of energy produced and the amount consumed. The higher the number, the better the system.
The heat pump consists of two units – one indoor part and one outdoor part. As all of Atria Optimum’s essential parts (such as the compressor and electronic controls) are located indoors, the heat pump is particularly well suited to locations with harsh weather conditions and a cold climate.
