Frequently asked questions
Short, factual answers about the WUNDER ALS 2110.
Is the WUNDER ALS 2110 Solar Keymark certified?
Yes. The Wunder collector range holds Solar Keymark certification issued through DIN CERTCO, and the certificate artwork is displayed on this page. Solar Keymark is the European quality mark that most national subsidy schemes require before a collector qualifies for funding.
How efficient is the WUNDER ALS 2110's absorber?
The selective-coated absorber reaches an absorptance of 0.95 while keeping emittance at 0.03, meaning it captures 95% of incoming solar radiation and re-radiates very little of it as heat loss. Aperture area is 1.89 m².
How many collectors do I need for my home?
For domestic hot water, plan roughly 1-1.5 m² of flat-plate collector area per person in southern climates and 1.5-2.5 m² per person in central and northern Europe, with 40-60 litres of storage per m² of collector. A family of four typically needs 2 collectors and a 300 L tank in Turkey or Spain, or 3 collectors and 300-400 L in Germany.
What warranty does the WUNDER ALS 2110 carry?
Solimpeks backs the WUNDER ALS 2110 with a 10-year product warranty, stated on this product page. Have the guarantee certificate stamped by the seller and follow the manual's operating conditions to keep the warranty valid.
