District heating is not a new invention. In fact, the technology dates back to ancient times. In ancient Pompeii, warm water from nearby sources was piped to the city’s houses. In Denmark, the first modern facility was built in Frederiksberg in 1903, and since then there have been many developments in production methods and piping systems.
Nowadays, heating is produced in a wide variety of plants, ranging from large coal-fired power plants to decentralised biomass plants and solar heating and geothermal systems. There is particular focus on the development of heat supply from renewable energy and CO2-neutral fuels such as wood pellets and wood chips.
isoplus has supplied district heating pipes to Danish plants since 1989, and the development of piping technology has been rapid. Our customers are increasingly demanding reductions of heat loss. Therefore, we are constantly researching and developing ways to reduce heat loss from the district heating pipes.
