The hybrid solar panel which produces electricity and boosts your hot water and heating production, coupled with a geothermal heat pump (glycoled water/water). The non-insulated model of the SPRING 4 can be used to recharge geothermal probes.
⇒ Up to 30% more efficiency for your geothermal heat pump
⇒ Aesthetic thanks to the black aluminum frame.
