Frequently asked questions
Short, factual answers about the WUNDER ALS HORIZONTAL 2117.
Is the WUNDER ALS HORIZONTAL 2117 Solar Keymark certified?
Yes. Solimpeks lists the WUNDER ALS HORIZONTAL 2117 as Solar Keymark certified; the DIN CERTCO certificates displayed on this page cover the WUNDER ALS and ANSG models, so request the ALS HORIZONTAL licence document from Solimpeks when a subsidy application needs it. 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 HORIZONTAL 2117'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.
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 HORIZONTAL 2117 carry?
Solimpeks backs the WUNDER ALS HORIZONTAL 2117 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.
