About energie-experten.org
Greenhouse Media GmbH, based in Hamburg, operates the portal energie-experten.org, which has existed since 2009. The company does not manufacture components; instead, it provides an independent expert network that connects homeowners with qualified specialist companies from the fields of photovoltaics, solar thermal, heating technology, thermal insulation and energy consulting. The editorial team produces guides, specialist articles, news and project reports on renewable energies and energy-efficient construction and renovation; content is regularly updated and editorially reviewed before publication. Via an enquiry system in place since 2013, interested parties can obtain up to five quotations from specialist companies free of charge and without obligation. In addition, the portal offers online calculators (heating planner, solar calculator, insulation cost calculator, among others), a manufacturer overview and best-practice project reports. Project partners include Vaillant, Stiebel Eltron, Viessmann, Buderus and E3/DC.
