The Baxi Combi Instant 105 HE – again with the built-in advantage of recognisable design - is SEDBUK Band B rated and provides instantaneous hot water at 12.1 litres per minute flow rate (at 35° temperature rise). It comes complete with a pre-plumbing jig and wall plate, and delivers a modulating CH output of 11.3kW to 31kW (condensing). Independent user controls for CH and DHW are neatly hidden away, along with status indicators for diagnostics and end user operation. An integral timer is optional, and there are extensive flue options.
