SmartLine SLE...

The incredible heating surface area of the SmartLine stainless steel cylinder can take as much heat as a domestic condensing boiler can give it. This means the boiler will work in condensing mode for much longer than if it was working with a conventional coil cylinder,
therefore giving greater fuel efficiency.

High Outputs – Fast Recovery
At a time when consumers are demanding ever higher performance from their hot water installations, the traditional coil-based cylinder is often hard-pressed to keep up with demand. ACV Tank-in-Tank technology represents a significant advance in the science of hot water storage... so much so that, in virtually every situation encountered, the coil-based cylinder is completely out-classed.

Tank-In-Tank Technology
ACV’s advanced implementation of thermal storage technology is tried and tested and is remarkably simple, efficient and reliable. An inner stainless steel hot water cylinder is heated by primary water circulating through a surrounding outer tank connected to the boiler in the usual way. A much larger heat transfer surface means that Tank-in-Tank units recover much faster than any other kind of hot water storage device - and keeps boiler cycling to a minimum.

Resistance to Scaling
The special design of the inner cylinder not only helps ensure scale-free operation but also avoids the sediment problems that plague conventional cylinders.
