Thermosiphon system Simple and efficient hot water heating A solar hot water system that attracts attention thanks to its fast installation, minimal maintenance requirement and high efficiency. The system operates on the thermosiphon principle, meaning that heat transfer occurs entirely by means of natural convection, without pumps and control units. The solar fluid heated in the collector rises and transfers heat through a highly efficient jacketed shell and tube system, with riser to ensure optimum stratification, to the drinking water in the enamelled tank. High-selectivity harp absorbers are used to guarantee the highest possible solar yield in this system.
Modular flat collector with aluminium frame and laser-welded full-area absorber with high-selectivity coating and meandering flow guarantees the best solar yield
Enamelled hot water tank with heat exchanger with jacketed shell, unique with two risers for optimal solar charging and hot water output. Two integrated sacrificial magnesium anodes. Electrical secondary heating can be retrofitted.
The galvanised steel profiles allow upright or parallel roof installation. Thanks to the special design the frame can be quickly and easily erected and has a high load bearing capacity
Piping and accessories
The thermosiphon system comprises all pre-insulated pipes and fittings required for installation. All necessary pressure relief valves and frost protection are included with delivery.
CoversThe piping is additionally protected and the system's appearance optimised by two lateral piping ducts and a front cover.
Thermosiphon systems are systems for producing heat from solar energy operating on the thermosiphon principle. The thermosiphon is a passive design, which allows heat transfer using natural convection ideally in a vertical, closed fluid loop. The advantage is that it avoids using a conventional pump, which keeps the complexity and costs of a thermosiphon system low. The thermosiphon system is available in three designs. They are characterised by high-selectivity coated harp absorbers and tank sizes perfectly coordinated with the system, together with unique charging properties. All necessary pipes, fittings and frost protection are included with delivery.
