The Thermia Legend is a geothermal heat pump that offers excellent year-round efficiency thanks to its unique technology. The Thermia Legend, with a seasonal coefficient of performance (SCOP) of 5.24 (Thermia Legend 10 B0/W35 according to the EN14511 standard), allows for up to a 75% reduction in energy consumption. SCOP is an indicator that describes the heat pump's performance throughout the year, in both warm and cold seasons. It shows the ratio of energy produced to energy consumed. The higher this factor, the better the system.

All in one - heating, hot water and cooling

SCOP 4,72-5,24
Management via mobile app
Low noise level

Thermia has set the goal of enabling a healthier lifestyle and reducing our ecological footprint. Therefore, the Thermia Legend is the first commercially available geothermal heat pump with the more climate-friendly refrigerant R452B, which has the lowest GWP value of 698. Additionally, due to its unique construction, it requires less refrigerant than other heat pumps, resulting in a very low CO2 equivalent.
