Product Overview

The SBS cylinders come into their own where space is at a premium, as they are buffer and instantaneous water cylinder in one. This enables the highly effective indirect coils to improve the hygiene inside the cylinder since only smaller amounts of DHW need to be kept hot to deliver hot water to the entire house. The SOL versions allow an additional renewable energy source to be integrated easily into the system.
