Deildartunguhver thermal spring produces 180 liters of water per second, the largest output of any thermal spring in the world. The water temperature in Deildartunguhver is 212°F (100°C). The total production capacity of Deildartunguhver and two neighboring boreholes is 62 megawatts.

The water in Deildartunguhver originally fell down as rain on the planes above Borgarfjörður and Langjökull glacier about one thousand years ago, before it came there through underground channels and was heated up by the hot rocks of an intrusion.

Deildartunguhver was cited to the Nature Conservation Register in 1978.

Water from Deildartunguhver has been utilized for central heating since 1925. The Akranes and Borgarfjörður Heating Works Company (HAB) runs Deildartunguhver and owns all assets relating to the distribution system. Because Deildartunguhver is only 19 meters above sea level, the hot water needs to be pumped through the distribution pipes. The distribution pipe connection Deildartunguhver to Akranes, Borgarnes and Hvanneyri was construced in the years 1979-1981. The pipe runs a total of 74 kilometers and is considered the longest of its kind in the world.

The water reaches Akranes from Deildartunga in approximately 24 hours. On average, the water temperature is 170°F (77°C) at Borgarnes, 163°F (73°C) at Akranes, and 149°F (65°C) in rural areas.
