AquaSol Cylinder Ref: AqualSol An indirect coil from the solar collector pre-heats water in the AqualSol combi sylinder to feed the combi boiler. The boiler then supplies hot water on demand to the tap or shower. During the summer months water in the combi cylinder may require no further energy from the gas fired combi. Even during the winter months water in the combi cylinder is pre-heated to such degree that it can save 20 - 30% of the energy normally required by a gas-fired combi.The AquaSol cylinder comes complete with intergral drainback vessel, pump and controls to allow automatic emptying of the roofmounted solar colector during times of possible frost damage or solar overheat.Techincal DataDimansions - 1078 x 540 x 520mm (h x w x d)Combi cylinder tank material - Stainless steelGross Weight - 112KgEmpty Weight - 22KgCollector flow connection - 10mmCollection return connection - 15mmCold water connection - 15mmHot water connection - 15mmMax mains supply pressure - 12barMin mains supply pressure - 1.5.barPressure and temperature relief valve - Pre-fitted How it works
