The Tulikivi fireplace is an unique contender at the Kyoto Conference on Climate. Proper woodburning does not affect the atmosphere's carbon dioxide level, therefore a Tulikivi does not promote the greenhouse effect. Dry firewood will burn extremely clean in a Tulikivi fireplace, thus producing the same level of carbon dioxide as would be released by the normal process of natural wood decay. The same applies for the nitrogen and sulphuric dioxides levels in comparison to emissions of fossil fuels.

An environmentally conscious person burns dry wood in the Tulikivi fireplace.
The thermal value of different wood types (as mentioned above) is approximately 4.1 kWh/kg in 15% humidity. The energy content of 2.5 kg of firewood equals that of one liter of oil. One cubic meter of firewood releases an equal amount of energy as 190 liters of heating oil (in Finland).
The Tulikivi fireplace is a heating system dramatically reducing electrical and oil consumption necessary during the winter.
Normally, over half of the home's annual heating consumption is incurred in the three coldest months of winter. When the Tulikivi fireplace is used during the heating season, it supplies over 50% of the required heat output, while consuming only 10% of the total annual thermal energy requirement. On an average, six cubic meters of firewood is needed to achieve results.

In the Tulikivi fireplace, firewood burns cleanly, with an even draft and hot flame. Thermal energy is quickly stored in the fireplace's stone, which releases heat slowly and evenly into the room. The Tulikivi fireplace is efficient and produces minimal emissions. The smoke gases produced by burning wood contain very few substances harmful to the atmosphere. The sulphur level found in wood is approximately 0.05%, making sulphur dioxide amounts in smoke gases very low. The nitrogen level in wood is negligible.
The Tulikivi fireplace's emissions and efficiency exceed the requirements set by German norm DIN 18891, which ensures the environmental-friendliness of wood-burning fireplaces.
Warning: The most harmful element found in smoke gases is carbon monoxide, which may enter the room should the flue be closed too early. The flue must not be closed before the wood and coals have burned out completely. It is therefore recommended that a 4% bypass flow be made in the flue plate to further prevent the danger of carbon monoxide build-up.
