"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."

Fall is the perfect time of year to give your heating system a tune-up. Before chilly autumn nights give way to frigid winter ones, you’ll want your heating system to be up for the task ahead.  T.H. Malloy Energy  is a full-service heating company that offers tune-ups as well as system upgrades and replacements. These services could save you a lot of money in the long run, and more importantly, keep you and your family safe. Here are the kinds of things we look for when performing maintenance on your heating system:

Proper Air Flow

We inspect and remove any blockages from the system. This ensures that you feel the full amount of heat your system is producing. If a block exists and is not removed, the system works harder, uses more energy and wears itself out faster.

Carbon Monoxide Leak

Carbon monoxide is a colorless, odorless gas that is difficult to detect and extremely dangerous. Regularly scheduled maintenance and cleaning reduces your risk of being exposed to carbon monoxide. Whether you get your system tuned up or not, however, having working carbon monoxide detectors installed in your home is a must for your family’s safety.

Reduce Repairs

An ounce of prevention is worth a pound of cure! In other words, small fixes are easier on your system and your wallet. You can extend the life of your heater by keeping it clean and fixing small problems when they happen, as well as scheduling yearly tune-ups.

Household Changes

Is your household expanding due to a relative moving in or a newborn? Has there been a recent construction or remodeling work done on your house in fall or summer? Has someone made changes to your home heating system since last winter? If any of those apply to your household, you should consider scheduling maintenance and contact the office for proper deliveries to make sure that your home is ready for winter.

Cleaner Home

A clean system will pump cleaner air into your home. Scheduling a fall tune-up now will remove dust and allergens to maintain cleaner air in your home throughout winter. Since your home doesn’t see much ventilation during the winter months, you don’t want to skip the fall maintenance to ensure the recycled air is clean as can be.

For all your heating needs,  contact  T.H. Malloy Energy!

Biodiesel is a renewable and clean burning fuel source that is made from used (recycled) vegetable oils, animal fats, or recycled restaurant grease. It is said to produce less pollution and greenhouse gas than standard petroleum diesel formulations and has many other benefits for consumers.

Renewable energy: Unlike petroleum products that have the potential to vanish in the coming years, biodiesel is a renewable energy source and can be locally produced on-demand.

No engine modification required: One of the best things about biodiesel is that it can be used in an existing diesel engine with little to no modification required. Because of this, it can replace other fossil fuels used in standard diesel formulations. It also improves the lubrication in the engine and thus can increase the life of the vehicle.

Less greenhouse gases : When fossil fuels are burned, gases like carbon dioxide are released into the atmosphere. Over time this raises the atmospheric temperature which has been connected with global warming.

Go local: One quarter of all the fossil fuel used in the United States are purchased from foreign suppliers. By contrast, biodiesel is manufactured with local products, thereby eliminating our reliance on foreign oil.

Less pollution: Standard crude oil must be refined before it can be used in diesel engines. This process releases many harmful toxins in the air causing greenhouse gases. Because biodiesels use vegetable and animal oils, the refining process releases less toxic chemicals into the environment.

Eco-friendly: Biofuels release less carbon into the atmosphere, so they are better for the environment.

At T.H. Malloy & Sons , we are proud to offer our customers biodiesel as a fuel alternative. Our fuel is manufactured by Newport Biodiesel, using recycled cooking oil from restaurants right here in Rhode Island. This eliminates a waste stream, therefore the product is used cradle to grave.

In addition to being eco-friendly, our biodiesel is approved by the US Department of Transportation and is ASTM certified. It can be used in homes, buses, pick-up trucks, heavy equipment and marine vehicles as well as any other equipment with a standard diesel engine.

Our story began in 1935 with Tom and Mae Malloy in the villages of Ashton and Berkeley, delivering home heating fuel to their neighbors and friends in Cumberland, Rhode Island. Tom continued his father’s dream for over fifty years. Our story continues with Tom’s children, Tom, Jim and Brett Malloy with the belief in the same values and work ethic that T.H. Malloy was founded.

T.H. Malloy and Sons, Inc. has grown to a company that still specializes in home heating delivery and service throughout all of Rhode Island and Southeastern Massachusetts. Propane and motor fuels make us more diverse in the heating industry and heating and cooling installations enable us to be known as a full-service heating company.  

Tom Malloy lives with his two children in Cumberland, Rhode Island. Carrying on his father’s quiet strength and integrity as President of T.H. Malloy & Sons, Tom believes in the value of this family-owned and operated company.

May of this past year, T.H. Malloy lost a great man, Thomas J. Malloy. The Malloy family appreciates all the support over these past few months. T.H. Malloy will continue in his memory.

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.
