Abstract

The Department of Forestry of the Work Efficiency Institute monitored 10 electrically heated households with wood-fired fireplaces as auxiliary heat sources in the Nurmijaervi municipality. The monitoring covered four months, the period 11.12.1990 - 10.04.1991. Each household recorded the events connected to heating and weighed the amount of wood they used. Additionally, the power consumption in each household was measured at intervals of one hour. The purpose of the study was to clarify the use of fireplaces in electrically heated houses and the possibilities for levelling power consumption peaks. This was accompanied by detecting the heating habits, the current situation in using the fireplaces and future plans. Each household monitored had a heat retaining hearth and a wood heated sauna. Five of the houses had wood-fired kitchen ranges and seven had wood-fired stoves. The heat retaining hearths were the most important source of auxiliary heat and they were used on the average 1.8 times a week. An average of 25 kg of wood was consumed weekly by heat retaining hearths. The firewood used in the households was usually a mixture of species with moisture contents varying in between 20 - 30 %. In the households monitored, wood compensated electricity on  More>>

An average of 25 kg of wood was consumed weekly by heat retaining hearths. The firewood used in the households was usually a mixture of species with moisture contents varying in between 20 - 30 %. In the households monitored, wood compensated electricity on average 19 %. Heat retaining hearths made it possible to achieve reductions of 1 - 2 kW of power consumption peaks. Wood heating was not consciously timed to coincide with power consumption peaks. The time of heating up of fireplaces was determined mainly by the time of a day when members of the family returned home from work. The users were generally satisfied with direct electrical heating and wood-fired fireplaces. Eight out of ten households monitored would choose the present heating system if they were to build a new house.}
