Drammen Fjernvarme District Heating is a district heating system in Drammen, Norway, a regional capital some 65 km west of Oslo. The heat pump was manufactured by Star Refrigeration in 2011 with three systems giving a combined capacity of 14 MWs to central Drammen providing 85% of hot water needed for the city. The district heating system is owned and operated by Drammen Fjernvarme who have the rights to the concession area given by the Drammen Municipality. This requires all new buildings larger than 1000 m2 to be built with a water-based heating system and connected to the district heating system. The heat pump uses the natural refrigerant ammonia that has a zero global warming potential and is not a greenhouse gas. The heat source is seawater that is taken in around 8 or 9 °C from a depth of 18 m and is cooled by low pressure liquid refrigerant. Using a vapor-compression refrigeration cycle, the system heats district water from 65 °C to 90 °C for use in building heating and hot water systems. The system has an average coefficient of performance (COP) of 3.0 which means 1 unit of electricity is combined with 2 units of heat from the seawater to provide 3 units of heat to the district heating circuit. With the low cost of hydro-based electricity, it is cheaper to run a heat pump than a gas or electric boiler. In addition, the compressor technology used in the Drammen heat pump is the single screw compressor from Vilter (Emerson). Its internal design allows for balanced forces allowing it to perform with a very long bearing life at more than 120,000 hours for normal refrigeration compressors.The heat is extracted from a local fjord whose water temperature is around 8 °C. The water is heated from recovered energy at a temperature of 120 °C. A city ordinance requires most new buildings to exploit this form of heating.

Strømsø

Strømsø is a borough of Drammen, Viken, Norway.Strømsø is located at the southern side of the river Drammenselva. Until about 1600, Stømsø was an island surrounded by the Drammenselva, but was later made landfast. In 1728 Strømsø was granted rights as a trade center by the king, and these rights were expanded to full trade rights in 1745. In 1811 Strømsø and Bragernes (on the northern side of Drammenselva) were united to form the town of Drammen. Strømsø has sports facilities, retail, office, industry and schools. Most of Strømsø consists of residential areas. At Strømsø we find Drammen railway station, being a junction for the Randsfjorden Line (connecting to the Bergen Line crossing the Hardangervidda), the Sørlandet Line (leading to Kristiansand and Stavanger) and the Vestfold Line. The main part of Drammen Harbor is situated at Strømsø. Opened in 1925, the Drammen shipyard (Drammen Slip og Verksted) was an important part of Drammen's industry until it closed down in 1986. The historic crucifix shaped church Strømsø Church (Strømsø Kirke) which was opened in 1667 is located in Strømsø. The tower of the church was not built until 1694. The church's architect was Daniel Knoff.During the first part of this century the old industrial area of Strømsø, formerly known as Grønland, has been remodeled and transformed into a Science Park (Kunnskapsparken), providing facilities for several governmental institutions such as the police authorities, County offices and the campus for Buskerud University College, Norwegian School of Management - BI Buskerud, Telemark University College (TUC) and Drammen library.
