Saunier Duval has added to its wide electric boilers offer the new AQ-Elec series for the production of DHW, featuring a modern design, an attractive and practical digital display, and available in a full range of models from 50 up to 120 litre vertical mount and in cylindrical or prismatic shape for all outputs.

Made of high density polyurethane, its effective insulation keeps the temperature stable. This avoids a high number of resistance switch on’s, which implies big energy savings, lower costs and environmental protection. Furthermore, they are adjustable in a wide temperature range - 30 to 70°C -, allowing for its installation as support to solar energy solutions, and the insulation of these devices is CFC-free. The high sensitivity adjustable thermostat allows for the maintenance of accumulated water at the desired temperature. In case of failure, and according to the European regulation, a security thermostat will be activated that immediately disconnects, avoiding the risk of burns.

An anti-freeze safety will activate the resistance when the water temperature drops below 10°C and rises it up to 15, which avoids freezing breaks. An hydraulic system protects the device against pressure rises avoiding its deterioration. Finally, the tank, made of steel plate, is protected inside by a glaze housing vitrified at 900ºC. This, together with the magnesium anode and some dielectric sleeves, avoids corrosion problems, reveals the company’s press release.
