Oil Tank Installation & Replacement

When your oil tank is aging, leaking, or failing inspection, you need a certified technician who gets it done right — not a crew that cuts corners.

An oil tank that is rusting, leaking, or flagged during a home inspection is not something you can put off. Whether you are replacing an aging single-wall steel tank in a basement or upgrading to a double-wall tank for added protection, the installation has to be done correctly the first time. At Shelly Heating and Cooling, we are Roth certified and handle both standard steel and double-wall oil tank installations across Winchendon, Gardner, Athol, Fitchburg, Templeton, and throughout Worcester County and Franklin County.

This is a family-owned business built on doing the job right and being honest about what you need. We do not upsell you on a tank you do not need or push you toward a more expensive option because it is more profitable for us. We look at your situation — tank age, location, condition, and local code requirements — and recommend what actually makes sense for your home.

Before any work begins, you get a clear answer on what the installation involves and what it will cost. No vague estimates, no surprise charges when the job is done. If your existing tank can be properly decommissioned and replaced in a single visit, we tell you. If there are complications — site access, old line replacement, or permit requirements — we walk you through that honestly upfront. Call Shelly Heating and Cooling at (978) 868-3403 and let us take care of it.

What We Offer:

Double-Wall Oil Tank Installation — We install Roth double-wall oil tanks, the preferred choice for homeowners who want maximum leak protection and long-term peace of mind. Roth tanks carry an industry-leading warranty and meet the strictest environmental standards.
Single-Wall Steel Tank Installation — Standard steel tanks remain a reliable and cost-effective option in the right setting. We install steel tanks that meet all applicable codes and perform a full inspection of the surrounding area before and after installation.
Tank Replacement & Old Tank Removal — We handle the full job, from draining and decommissioning your old tank to hauling it out and installing the new one. You are not left coordinating multiple contractors.
Oil Line Inspection & Replacement — Old or corroded oil lines are often discovered during a tank swap. We inspect existing lines and replace them when needed so your new tank starts off connected to a clean, reliable system.
Indoor & Outdoor Tank Installations — We work with basement, utility room, and exterior tank setups depending on your home layout and local code requirements.
Permit Coordination — Oil tank installations require permits in Massachusetts. We handle the paperwork and ensure the installation meets all state and local requirements so you are covered.
Post-Installation System Check — After every tank installation, we confirm that the system is connected properly, lines are tight, and your burner is firing cleanly before we leave.
