The Roth DWT series delivers reliable double-wall fuel storage for boiler and stove installations. Designed for installers who value speed and safety, this line includes the DWT 1000L and DWT 1500L oil tanks, built to handle residential and light commercial heating loads without compromising on space or performance.

Straightforward Connection Kits

Hooking up your Roth DWT tanks is quick and error-free. The basic G and GR fittings are ready for standard supply and return lines, while the sequential R and RR connections make linking multiple tanks simple. All fittings are clearly labeled, so you can focus on tight seals and proper alignment instead of hunting for adapters.

Double-Wall Protection That Meets Code

Every DWT tank features a double-wall design that prevents leaks and keeps your installation compliant with environmental standards. The inner vessel holds the fuel, while the outer shell acts as a safety barrier. This means fewer callbacks, easier inspections, and a cleaner job site for you and your crew.

Flexible Sizing for Any Boiler or Stove

Pick the DWT 1000L for compact utility rooms or the DWT 1500L when you need extra runtime between refills. Both models are engineered to pair seamlessly with standard heating units. Their low profile and reinforced bases make placement on concrete pads or floor mounts straightforward, saving you time during rough-in.

Built for Installers Who Want Reliability

Roth DWT tanks cut down on guesswork and deliver consistent performance season after season. With clear connection points, corrosion-resistant materials, and a design that prioritizes real-world installation conditions, this series is a smart upgrade for any boiler or stove project. Choose Roth DWT for faster installs, fewer service calls, and long-term customer satisfaction.
