The solar thermal kit Hermann Saunier Duval HelioSet pressurized PS 3 are constituted by a series of places solar collectors on the roof, capable of absorbing the radiation from the sun to heat the heat transfer fluid.
The heat transfer fluid is transferred from the collectors to the kettle FE S BM by means of a circulator in this solar pump group, managed by a control unit, which detects when the temperature in solar collectors is higher than that present in the kettle.
The kettle FE S BM, place inside the building, stores the hot water to be used by the user when needed. The components in the system are:
- Collector CFS 2.5 / 3 vertical plane, for overhead installation with gross area 2,51 sqm and 2,35 sqm net, absorber with selective treatment, hydraulic circuitry meander with 4 water connections with quick coupling, structure with aluminum frame anodized rear sheet of embossed aluminum protection. The fixtures available to allow you to install the collectors CFS 2.5 / 3 on a flat roof or a pitched roof, thereby covering all types of cases.
- Kettle FE S1 150 BM 150 liters monoserpentino or kettles FE S2 BM 250/350 from 250/350 liter twin coil, all glazed and suitable for hot water up to a maximum temperature of 85 ° C. Water connections positioned in the upper part of the tank (ErP class B).
- Solar pump unit complete with control unit GHS8 installable on the kettle. Ability to install a 2.5 kW electrical resistance in the solar circuit, which allows you to heat the domestic water storage tank with no risk of scale formation.
- Solar expansion tank and premixed antifreeze.
