What is the difference between the non-insulated and insulated versions of the SPRING panels?
We propose two versions of our panel: a non-insulated version and an insulated version. The non-insulated version is adapted for low-temperature applications: for instance, coupling the panels with a water-water heat pump (a system that only exists for commercial buildings currently, with an operational temperature of about 20°C) and pool heating (with an operating temperature of about 25-30°C). The insulated version of our panels is adapted for domestic hot water (DHW) with an operating temperature of about 50-60°C.
