Roth Double Wall Tanks are available in four (4) sizes for storing domestic heating oil and diesel, the 400 L (110 gal.), the 620 L (165 gal.), the 1000 L (275 gal.), and the 1500 L, (400 gal.). They can be installed individually both outside and inside.

To increase interior storage capacity, up to five Roth DWT tanks can be grouped together,
depending on local building codes.

Roth has developed a system for installing tanks in groups with common filling and venting pipes thereby reducing the need for pipes, while facilitating supply to the central heating system.
