Hygienic combi tank SUNSYSTEM HYG B EF – without coil
To produce and accumulate sanitary hot water and hot water for space-heating system.
Coil-in-Tank construction- Flexible stainless-steel coil for sanitary hot water +Buffer tank powering space-heating system.
Sanitary water heats up instantaneously as it flows through the large surface stainless coil. Thus water is delivered hot while still fresh and clean of depositions.
Allows utilization of up to three external heat sources and an optional electric heating element.
Energy Efficiency
Aesthetic PVC jacket
Easy installation
Convenient inspection opening
Optional kit for electric heating
