This leaflet from the German association VdZ (Forum for Energy Efficiency in Building Equipment) aims to explain to consumers how a periodical check and inspection of the heating system can help to keep a high energy efficiency and a reasonable energy bill. The 10 points of the heating system that have to be looked at are shown in photos of the document. They have to be checked by visual inspection or measurements.
A check-list is provided (Punkte-Bewertung Heizungs-Check) with an evaluation based on a scale of points, which allows for assessment of the heating system efficiency.
This document is available on the website Intelligent heizen (Intelligent heating), a consumer-oriented information and service platform of VdZ (Forum for Energy Efficiency in Building Equipment).
