One family houses

  • Energirenovering giver effektiv og styrbar varme

    "Det trådløse CF2+-system eliminerer behovet for dyr kabellægning, og næsten al renoveringsarbejdet blev udført i styringsskabet. Arbejdet gav ikke noget rod, og både installation og idriftsætning var meget ligetil."

  • Renovering af et privat hjem

    Et stenkast fra Frankfurt-am-Main i Tyskland ligger et hus, der er bygget i 1984 og udstyret med det, der dengang var topmoderne isolering.
    Da de nuværende ejere overtog huset, konstaterede de, at udover at tagisoleringen var utilstrækkelig efter nutidens standarder, så kunne gulvvarmen ikke styres i tilstrækkelig grad, hvilket resulterede i et stort energiforbrug.

    En stor udfordring
    Det eksisterende gulvvarmesystem var længe om at varme op, praktisk taget umuligt at styre og kørte konstant på en for høj flowhastighed. Det resulterede i for høje rumtemperaturer og et højt niveau af energispild. Derudover var fordelerrørets styreventiler ekstremt tilkalkede af gamle lækager, og aktuatorerne var helt afbrudt og deaktiverede.

     

  • Varmestyring i de enkelte rum

    Der blev installeret en CF-RF-termostat med infrarød gulvføler i entreen for at sikre en passende basistemperatur. Denne enhed regulerer også gulvtemperaturen, når der anvendes sekundære varmekilder, såsom pejs eller brændeovn. Andre rum blev udstyret med CF-RD-rumtermostater. Der blev tilføjet en CF-RC-fjernbetjening til at holde øje med timingen, og det gamle fordelerrør blev udskiftet med en FHF-F med nye TWA-A-aktuatorer.

    Forbedret komfort og energibesparelser
    Den største fordel i forhold til den gamle løsning var, at man opnåede en reel varmekomfort. Temperaturen kan nu indstilles individuelt og reguleres i hvert enkelt rum, hvilket giver betydelige energibesparelser i en husholdning.
