ACO is a compact and easy to insall with plenty of hand and tool room and easy access to all connections from the front. This all new high efficiency boiler has a comprehensive specification including electronic ignition, automatic by-pass, anti scale, anti-frost device and self-diagnostics sequence. Ariston's standard water and gas connections jig-kit is supplied as standard with the ACO Combi (along with a filing loop) - this means that the new ACO combi can be fitted as a replacement for an older Ariston combi on it's existing Jig-kit.

ACO boasts the very latest in technology. A bespoke PCB, designed and produced in-house by Ariston, which allows true flexibility of boiler function. At the heart of the boiler is a new stainless steel primary heat exchanger, produced using the most advanced automotive technology, which has been designed for long life. The ACO has also been designed from the outset to be compatible with Ariston's futuristic remote diagnostics package (currently under development) which will change the way boiler servicing is carried out.
