Stainless steel hot water tanks for homes, industry and marine, with smart controls that heat water when power prices are low
About Oso Hotwater
OSO Hotwater manufactures stainless steel hot water tanks for residential, commercial and marine use at its factory in Hokksund, Norway. Its SUPERCHARGED and CHARGE Retrofit smart controls heat the water when electricity prices are low, based on Nord Pool spot prices and the household's hot water use, and the OSO inCHARGE app lets owners manage the heater.
Customers include homeowners, industrial users who buy commercial tanks from 300 to 15 000 litres, and marine and offshore operators. Products are sold through a dealer network, and the company signed a distribution agreement with Dahl in Sweden in 2026.
The company has produced hot water heaters since 1932, and the legal entity OSO Hotwater AS was founded in 2003. Its headquarters and factory are in Hokksund, with regional sales and service offices in Oslo, Stavanger, Godvik and Trondheim.
