Deildartunguhver is Europe’s most powerful hot spring in Europe. It provides 180 l/sec of 100°C hot water. Most of the water used for central heating in the towns of Borgarnes and Akranes is taken from Deildartunguhver. The hot water pipeline to Akranes is 64 km long, the longest in Iceland and the water is about 78 – 80 degrees when it reaches Akranes. If you take a shower anywhere within a 65 km radius of the spring, you have already bathed in the hot water from this powerful spring.
