SIRIO W: Geothermal Multifunctional heat pumps-Image

Geothermal multifuncional heat pumps for summer air conditioning, winter heating and simultaneous hot sanitary water production up to 65°C (149°F).

 

SIRIO W is a geothermal heat pump unit with total recovery equipped with two water circuits, one dedicated to summer air conditioning and winter space heating and the other one dedicated to hot sanitary water production.

  • 9,44 - 40,72 kW - Cooling capacity 
  • 13,08 - 54,96 kW - Heating Capacity
  • HOT WATER PRODUCTION UP TO 65°C (149 °F) 

 

OPERATING MODES 

  • Winter space heating and hot sanitary water production 

During winter SIRIO W provides hot water for heating or sanitary purposes (with higher priority for sanitary uses).

  • Hot sanitary water production 

During middle seasons SIRIO W provides hot sanitary water.

  • Summer air conditioning and hot sanitary water production

During summer SIRIO W produces cold water for cooling and free hot water
for sanitary purposes.

ADJUSTABLE SET POINT FOR ANY USER

With the multifuncional technology it is possible to set different and completely indipendent set points for summer air conditioning winter space heating and hot sanitary water production. The unit works with different COP, one for winter space heating, one for sanitary purposes, obtaining an increase in the efficiency (average COP) of the unit during the whole year. Therefore, the  during the whole year reaches very high values.
