The Energy 18S system boiler is a high-efficiency, high-quality boiler that is designed using automotive grade aluminium. It is designed to last a lot longer than your typical copper or alloy heat exchanger and also dramatically reduce energy bills. The new, beautifully designed heat exchanger is extremely quiet, providing a silently operating boiler that you will hardly notice is on. The Energy System boiler has a modern, high-impact design that will suit your customers' homes and comes with a bright, easy-to-read LCD display, a smart timeless case design and super quiet running. Energy just requires simple water flush cleaning for the heat exchanger, which means lower costs and no special cleaning tools. The patented 4-sided cooling reduces the stress on the heat exchanger, which means longer term reliability for your customers. This pack contains a horizontal flue for added convenience and value.
