Roth DWT heating oil tanks are available in four models: DWT 400 L, DWT 620 L, DWT 1000 L, DWT 1500 L, for storing domestic heating oil fuel or diesel fuel. They can be installed individually both outside or 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.
