Heating is an important component of quality of life for the residents of Latvia as the average outdoor air temperature is 2.1 o C during the heating season from October to April while in the summer months, there is a demand for hot water. District heating is used in approximately 80% of Latvian households, as well as in most public and industrial buildings. The fundamental mission of the district heating company is to ensure a reliable supply of heat at the lowest possible price, without harming the beautiful and green nature of Latvia.
