  • “The AeroFlow is an efficient electric radiator that heats our rooms within 20 minutes and thus reduces the heating time by 80%. One Maxi AeroFlow radiator is enough to heat our living room of 40 m², despite the relatively poor insulation of our apartment.”
    Yannik S.
    “A few weeks ago, I purchased your Aeroflow 1300 direct radiator from After making the necessary changes in the modern meter box, the electrician used the existing wires from the former night heater. Advantages of this radiator: modern slim-type design, excellent display, no operating noise, measured electricity savings of approx. 35%. With its 1300 kWh, it has replaced the 4 kWh night storage heater. I am absolutely impressed with this radiator.”
    Klaus Schütz

    "Thank you once again for supplying us with the highest quality electric surface storage heater. We can now use our garden house not only in the summer, but all year round – and we can also put guests up for the night. Thanks to the feet with casters, the heater can be moved to any place and it is therefore never in the way when you want to use the place for another purpose. But the best is the pleasant warmth - exactly like that form a tile stove in a country house - yet with much better air as we do not use wood as a fuel. We are delighted!"

  • „Absolut genial!
    Wir haben unser Ferienhaus komplett damit ausgerüstet, und sind begeistert. Einfach und unkompliziert. Die Gäste finden es toll und wir haben gegenüber unserem alten Nachtspeicher viel Stromkosten gespart - sehr zu empfehlen“
    Frank Fahr

    „Tolle Alternative zur Nachtspeicherheizung.
    Wir haben das Haus mit insgesamt 11 verschiedene Heizkörpertypen ausgestattet und sind damit sehr zufrieden. Der Austausch einer defekten Steuerung wurde unbürokratisch und schnell abgewickelt. Der Stromverbrauch für unser Haus gesamt mit Wasseraufbereitung, Heizung und restlichem Strom lag im letzten Jahr bei insgesamt 7.400kwh. Das ist ein Top Wert und unterstreicht nochmals die richtige Entscheidung getroffen zu haben.“
    Marcus Sell
    „Sehr zu empfehlen.
    Ich nutze die Heizung als Zusatzheizung in unserem Wohnzimmer. Damit haben wir auch bei niedrigen Temperaturen noch genügend Wärme, falls unsere betagten Gasheizungen nicht ausreichen.“
