OEG Solar storage tanks - highest quality "Made in Germany"!
The OEG solar storage tank 3Plus is suitable not only for heating up domestic water with boilers and low-temperature heating systems but particularly for the additional connection of a solar system.
The third smooth-pipe heat exchanger can be perfectly used for a return flow boost.
The storage tank is used as a new installation but also very often as a replacement tank. Thanks to the wide range of selectable coating colours and the various connection options, a combination with heat generators and solar systems of almost any manufacturer is possible.
The inner surface of the storage tank is coated with high-quality enamel to ensure the hygienic heating of drinking water. The generously-dimensioned heat exchanger surface of the lower smooth-pipe heat exchanger reaches down to the bottom of the tank, and thus provides a huge energetic advantage compared to many other products in the market.
The service hatch allows for convenient maintenance and cleaning of the tank.

Guten Morgen,
wir haben ein Verfahren entwickelt, durch dieses werden die Speicher nun eingeschäumt. Durch dieses Verfahren
und das verwendete Material ist es uns gelungen den Wärmeverlust nochmals zu senken.
Mit freundlichen Grüßen
