Vaillant auroSTOR twin coil cylinder

auroSTOR is a twin coil hot water cylinder in which one coil connects to the boiler and the other to solar collectors. It suits villas and guest houses building a solar-assisted hot water system.

Capacity: 300–500 L

On sunny days the hot water comes entirely from the collectors and the boiler only steps in when needed, which cuts summer gas use to almost nothing. The long hours of sunshine in Antalya shorten the payback period of such a system.

Magnesium anode protection and thick insulation guard the tank against both corrosion and heat loss. Checking the anode every year directly affects the life of the cylinder, so we include it in our service plan.
