The only functional difference between the two is exchanger position — front (11841) vs. rear (11842). At 14.1 kg the 11842 is heavier than the 11841 (11.8 kg); confirm whether the weight difference is due to the exchanger configuration or a manufacturing variance. The engine coolant-only restriction applies equally to both models — flag prominently for customers with raw-water-cooled engines. For customers deciding between Kuuma and Seaward rear-exchanger units, compare against the Seaward S1100 (698-S1100): Kuuma is 1500W vs. Seaward’s 1800W, and aluminum alloy vs. galvanized steel case.
