Kaugküte

Kaugküte is a term used in Estonian to denote district heating, a centralized system for supplying heat to multiple buildings through a distribution network. The concept describes a centralized heat source, such as a combined heat and power plant, a boiler house, or a heat pump facility, that produces hot water or steam for distribution.

In a typical kaugküte system, hot water or steam is generated at the central plant and transported through insulated pipelines to connected buildings. Inside each building, a heat exchanger or substation transfers the heat to the building’s heating circuits, enabling space heating and often domestic hot water. The system is designed to serve residential, commercial, and institutional properties within a defined network area.

Kaugküte systems can utilize a range of energy sources, including fossil fuels, biomass, waste heat, or renewable energy, and may be enhanced by technologies such as cogeneration (combined heat and power) to improve overall efficiency. Modern networks often incorporate smart metering and control systems to balance supply with demand and to optimize energy use.

Benefits commonly associated with kaugküte include higher overall energy efficiency, reduced local emissions, and the ability to utilize waste heat or renewable fuels that would be difficult to deploy for individual buildings. Centralized control can also simplify maintenance and enable better long-term planning.

Challenges include high upfront infrastructure costs, heat losses in the distribution network, and the need for coordinated operation across many buildings. Pricing and regulatory oversight are typically managed by energy authorities, with metering and billing based on heat consumption or connected capacity. The term literally translates to “remote heating.”
