System Expansion Vessel
The Baxi Ambiflo
™
Heat Pump has a 2 litre expansion vessel contained within the unit. This 2 litre
expansion is adequate on systems that contain up to 90 litres of fluid within the complete system. Larger
systems will require an additional expansion vessel.
Failure to ensure the minimum size of expansion vessel can result in premature failure of the expansion
vessel and associated system components.
