Study Project of Heating Methods for Single-Family Houses. Session 5.1 N.5.1.1

摘要

The aim of the study was to compile comparable data of energy consumption and acquisition costs for heating systems using electricity as their primary heat source. Energy consumption was recorded in 1000 new houses during 1-4 years. The reference group consisted of about 60 oil-heated houses. Consumer data have been analysed using linear regression analysis. In view of energy use the most advantageous system is a geothermal heat pump, but on the other hand it involves the highest cost of acquisition. As far as the overall economy is concerned, i.e. when both energy costs and acquisition costs of the heating systems are compared, the best choice is direct electric heating. (ERA citation 10:033982)
