All WUNDER collectors are Solar Keymark certified, built with copper pipes, low-iron tempered glass and laser welding — rated to 130 °C / 10 bar and backed by a 10-year warranty. Applications: domestic hot water, pre-heating, pools and process heat.
The flagship flat-plate collector: ~82% absorber efficiency (79.4% gross) with a highly selective aluminium absorber (95% absorptance, 3% emittance). Gross area 2.4–2.59 m². For projects where every kWh of yield counts.
Premium selective collector (~79% / 73% efficiency) with rock-wool insulation, in six sizes from 1.79 to 2.97 m² — plus HORIZONTAL variants and ALS DRAIN for drain-back systems.
Selective-coated mid-range collector (~77% / 70% efficiency) with glass-wool insulation, 1.79–2.42 m² — the price/performance workhorse for DHW and pre-heating.
Economical painted-absorber collector (~67% / 64% efficiency) for budget-driven projects, pool heating and warm climates.
Hybrid panel producing electricity AND heat simultaneously: ~22% electrical + ~43% thermal efficiency, 590 Wp, 144 monocrystalline cells on 2.7 m². Integrated PV cooling boosts electrical yield.
Complete pumpless solar water heaters (120–350 L). TSM: AISI 316L flexible-pipe exchanger, no magnesium anode, maintenance-free, ~80–84% solar fraction. TSE: double-jacket exchanger with high-tech enamel.
