Full service home heating, motor, marine & diesel fuels

"I recently purchased property and was in the process of screening tenants and dealing with inspectors/contractors at the same time; I completely overlooked the oil levels at the time. It was late Friday afternoon when I realized I was out of oil and there was a pending snow storm that weekend. After calling many various oil companies, I reached T.H Malloy & Sons in Cumberland, RI. I explained my dilemma to your sales manager Hank, and he understood the gravity of my situation and treated me as if I were a long term customer. He drove to my property and arranged with the owner Tommy, to come right out and fill my two oil tanks. After he contacted the service department , within an hour a technician was arriving at my door and they made sure there were no frozen pipes, as it had been a very cold week, as well as confirm everything was operating properly. The whole process was very professional, and pleasant. Having a business that cares about their customers and deals with each client with care and attentiveness is rarely found these days. I recommend T.H. Malloy & Sons to anyone looking to be treated and respected as a person fairly, and not just another account number to add to the company books."

Fuel is the power source for almost everything we do. It allows us to get from point A to point B, runs machinery and keeps our world moving ahead. At  T.H. Malloy & Sons we are privileged to provide Rhode Island with the fuel needed to keep running strong. 


T.H. Malloy & Sons has been serving Rhode Island and Southern Massachusetts since 1935. Our family owned and operated business has grown a lot since then, offering full-service home heating and on- and off-road diesel and biodiesel. Our commitment to Rhode Island and the surrounding area has made us the State’s leading distributor and consumer of biodiesel.

Home Fueling

We offer our customers conventional heating fuel, BioHeat, B20 BioHeat and B100. BioHeat is a combination of #2 heating oil and locally produced Biodiesel. Our fuel is so efficient, it requires no modifications. It also provides a cleaner, more complete and energy efficient burn. BioHeat is also a renewable energy source that is biodegradable and appropriate for sensitive environments. And, because it is made right here in the United States it reduces our dependency on foreign oil.

The energy efficient products we offer save the customer money while providing comfort for their home. We can also provide hydro-air services, radiant heating and domestic hot water installation for high efficiency heating. And, convenient “will call” delivery service ensures you never go without. We also provide convenient budgeting and cap pricing so there aren’t any unwanted surprises.

Air conditioning services

With over two decades of air conditioning services, T.H. Malloy can help you choose the perfect system for your cooling needs. Our expert team can assist you in sizing your air conditioning system to the needs of the space while considering the aesthetics as well as your personal needs.

Business and fleet services

Whether your business needs are on land or sea, T.H. Malloy & Sons can provide the fueling you need. We offer on and off-road delivery services as well as fleet fueling with on-site delivery. We are also Coast Guard certified from Long Island Sound to Boston. And, just like our home heating services, we offer a variety of fuel choices including Eco-Friendly Biofuel and Biodiesel.

If you are looking for fuel for your home, business, or fleet, contact the experts and T.H. Malloy & Sons for a free estimate.

Tom Malloy has been a local business man in Rhode Island for over sixty years. Thomas H. Malloy & Sons, Inc. was founded in 1935 by Tom’s parents Tom and Mae Malloy. Over the past six decades, Tom has been a pioneer in the fuel industry, growing the business from pedaling kerosene throughout the villages of Ashton and Berkeley to a full service energy company to include home heating, motor fuels, propane, boiler and air conditioning service, and generator service. Over the past ten years, Tom was instrumental to introducing and expanding biodiesel fuel to Rhode Island through T.H. Malloy and his sons, Jim and Tom Malloy.

Tom has been a Cumberland resident his entire life. Married to Joan for over fifty-three years, Tom and Joan were blessed with three children, Tom, Jim and Brett and five grandchildren, Tommy, Jack, Wyatt, Kaya, and EllaMae. Tom enjoyed his simple, humble life, taking care of the business daily and spending time on the weekends with Joan and friends on Cape Cod.

Through the years, Tom has had many successes and accomplishments with T.H. Malloy. An active member of the Oil Heat Institute of Rhode Island, Tom was inducted into their Hall of Fame in 2007. Other recent acknowledgements and awards include:

  1. Northeast Diesel Collaborative Breathe Easy Leadership Award in 2015 for his outstanding efforts to reduce diesel emissions through his work with biodiesel;

  2. Northern Star of New England Clean Cities in 2014 for his successful collaboration with Newport Biodiesel to promote and utilize alternative fuels while powering a fleet of vehicles to run their business;

  3. Reader’s Choice Award in 2014 for outstanding customer service in the heating and air conditioning industry; and

  4. Citizens Energy Community Service Award in 2008 for Tom’s commitment to helping the residents of Rhode Island in need.

Because of Tom’s quiet strength, integrity and leadership, T.H. Malloy will continue on in his memory. He will be sadly missed by his family and friends. His grandson, Tom Malloy will accept this award on his behalf.
