Vision Plus has four combi models in the range: 25, 30, 35 and 40kW. The new Vision Plus combis offer complete flexibility in installation and performance. The 25C and 30C have small installation footprints, with dimensions of just 738 (h) x 405 (w) x 248mm (d). The rear flue option makes it easy to fit these in to kitchen cupboards. They are also lightweight too, at just 27kg for the 25C. The 35C and 40C are all about performance. Both models are still comparatively compact in size at 740 (h) x 420 (w) x 350mm (d). The 35C delivers a domestic hot water (DHW) flow rate of 14.2 l/min at 35°C temperature rise and the 40C 16.4 l/min. The wide modulation ratio of 1:8 means the 40C can provide a minimum of 4.9kW for heating and the 35C just 4.4kW. This ensures that boiler cycling is reduced, even when the central heating load is minimal.
