Solar thermal energy is now standard in many households. Our solar thermal products ensure effective, safe operation of solar energy systems for domestic water heating and back-up heating. The core of a solar thermal system is the solar controller, which uses solar collectors, storage tanks and circulation pumps to harness the powerful energy of the sun. It also monitors and controls the technical processes. The hallmarks of the extensive solar thermal product family are high efficiency and ease of operation. Thanks to Steca, the sun has become an everyday source of energy that can be used as a matter of course.
