Cascade boiler systems

The cascade boiler system is quick and easy to install thanks to the Plug & Play – principle. The diversity in configuration options enables the installation to be placed almost anywhere, whether it is an existing location or a new built.

Features Cascade boiler system

A.O. Smith delivers the entire package; it just needs to be put together. The quick fit hydraulic pipe work header fixes the boiler support frames with all the interconnecting pipework.
