The district heating system can use heat sources impractical to deploy to individual homes, such as heavy oil, wood byproducts, or nuclear fission. The distribution network is more costly to build than for gas or electric heating, and so is only found in densely populated areas or compact communities.
The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) [1] and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.

A weatherized building is protected from the outside elements in order to maximize energy efficiency. Amundsen–Scott South Pole Station. Weatherization (American English) or weatherproofing (British English) is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind, and of modifying a building to reduce energy consumption ...
In cold conditions, the main aim is to reduce heat flow out of the building. The components of the building envelope—windows, doors, roofs, floors/foundations, walls, and air infiltration barriers—are all important sources of heat loss; [35] [36] in an otherwise well insulated home, windows will then become an important source of heat ...
The use of sustainable energy sources and energy-efficient systems is encouraged to reduce greenhouse gas emissions. The main source of harmful greenhouse gas emissions is the type of heating systems being used. For example; central heating systems depending on what they use to burn/electricity consumed to heat the system.
“The loss of life, the injuries, the destruction of whole communities, the loss of property. It's a direct result of our failure to transition from fossil fuels and other major greenhouse gas ...
The major sources of indoor pollution include combustion and building materials. [4] Globally, 4.3 million deaths were attributed to exposure to IAP in developing countries in 2012, almost all in low and middle-income countries. The South East Asian and Western Pacific regions bear most of the burden with 1.69 and 1.62 million deaths, respectively.
The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria. Animated image showing how district heating works. District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water ...
