Correction factor f (Holzenergie Schweiz quality mark): A firewood boiler must be operated at nominal output for about 1 hour after starting. Additionally,
about 0.5 hour is required for heating up. As a rule, it is not possible to operate with the lowest possible output right from the start. The correction factor f
depends on the relationship between the nominal and lowest possible output levels and is individually set for each boiler (assumption: system reaches
nominal output 1.5 hours after starting).
Selection and combinations of accumulator tank CWK/CWK or CWK/CWP:
The accumulator tanks can be combined with one another in parallel in a flexible way. The connection set CW-
021 (accessory) can be used for the following tank combinations.
CaloWIN Premium with CaloWIN Klassik
CWK 700
Premium
(720 l)
CWP 800 (800 l) 1520 l
CWP 1000 (960 l)
Other combinations are also possible in series operation. In this case, the accumulator tanks must be connect-
ed by the client (no connection set is available).
