When it comes to the installation of a cylinder, one of the main issues customers face is size;

The Aquinox Compact was originally designed to be a discrete solution for pressurised hot water in small flats and student accommodation.


The unit's horizontal orientation allows it to be situated in under-sink units or small loft spaces. It's 75 litre capacity allows it to retain its compact size whilst providing pressurised hot water to sinks and showers.
