Storage tanks

The Oilon and Lämpöässä heat pump range is now supplemented with an extremely versatile and comprehensive selection of storage tanks. Our competitively-priced high-quality storage tanks come in a wide range of different tank and coil sizes for different needs and connection configurations. Most of our storage tanks feature removable insulation either as standard or available as an option, making them easier to handle and install in cramped spaces.

The required tank volume depends on the building and its water system configuration. Intended as external tanks for Oilon and Lämpöässä heat pumps, these storage tanks have lots of ports for connecting additional heat sources for supplementary heating.
