For decarbonization of the world’s energy supply not only power production but also heat generation must switch totally to renewable energies. Heat pumps could be one of the major alternatives for small and medium scale heat utilization. But, power driven heat pumps need electricity especially in winter time, when renewable power from wind and photovoltaics could be scarce. So a backup technology could be helpful. It is shown that a wood stove with water jacket for residential heating can lower peak power demand in winter time significantly. For older houses with radiation heating system the additional wood log stove could be run economical feasible with cheap wood resources.
