Local heating, especially ovens and stoves that are heated with log-wood, have been one of the most important types of heating in Estonian climatic conditions. During the second half of the 20th century, alternative types of heating were developed. For example, district and electrical heating. As the consumption of energy for heating houses has decreased, it has become relevant to use local heating options. For example, heat pumps, solar heating and solid fuel ovens and stoves could work in good collaboration. Regarding strict environmental standards, it has become important to increase the efficiency of fireboxes that use wood. During the reconstruction of heating devices, it is advisable to change the parameters of the firebox and the flue, to assure a high quality of combustion and efficient energy storage. This article is about heat technical experimentations with stoves with an Umwelt-Plus fireplace. To be more precise, it concentrates on measuring the energy of this stove with a copper thermistor, which stores the surface temperature during measurement.
