maar we wilden dit toch doen en niet direct kijken naar de terugverdientijd. En we hebben alles laten doen. We zijn wel volledig van het gas af. Voorheen zat er een warmelucht verwarming en waren ze 300 euro per maand alleen aan gas kwijt. Totale energierekening zat boven de 400 euro. Met een beetje geluk zitten we nu rond de 100 euro per maand. Daarmee verdienen we al 75.000 euro terug in 20 jaar. Zonnepanelen staan nog op de planning waardoor dit nog gunstiger wordt.
