What is the difference between the non-insulated and insulated versions of the SPRING panels?


We have three versions of our panel in our catalog:

  • SPRING3 and SPRING4 non insulated

  • SPRING3 and SPRING4 insulated

  • SPRING4 finned


Non insulated SPRING 

The non-insulated version is adapted for low-temperature applications: for instance, coupling the panels to geothermal probes with a water-water heat pump (a system with an operational temperature of about 20°C) and pool heating (with an operating temperature of about 25-30°C). 

Non insulated SPRING4


Insulated SPRING

The insulated version of our panels is adapted for domestic hot water (DHW) with an operating temperature of about 50-60°C. 

Insulated SPRING4


The finned version is designed for coupling with water to water heat pump and enable a better exchange with the ambient air.
