A boiler can manage the heating and hot water requirements in commercial facilities, apartments, and private homes, offering single or multiple heating zones. Choose from natural gas, propane, oil-burning systems, and models that use only electricity, and benefit from even, reliable and efficient performance. Whether you’re looking for a heat source for your radiator or radiant system, modern advances in design and technology make boilers a great way to heat, no matter the fuel source. Joseph Frederick & Sons offers a wide range of choices, and offers prompt installation, upgrades, maintenance and repair. Our NATE-certified team has the technical skills, knowledge, and hands-on experience to make sure your boiler meets your needs and expectations.

Time for a new heating installation? A boiler might be for you!

CarrierWith a boiler, the feel of the heat is unique. Rather than being introduced through a vent, heat is infused into the air for a more even and gentle comfort. Because boiler systems supply heat via closed tubing that can be fed through large old radiators, modern baseboard heaters, or hidden in floors, they don’t create dust in the same way as forced air heating. This dust can aggravate symptoms of asthma and allergies, whereas a boiler is a very clean form of heating. These systems have the advantage of room-by-room control. Easily designed with separate zones, a boiler allows heating of some parts of the house and not others, preventing energy waste. You can also adjust and maintain your indoor climate to your specific, exacting levels, customizing different rooms to personal preferences.

Knowledgeable installation of your new boiler is the key to ensuring satisfactory performance, conservation of energy, and long life of the equipment. Incorrect installation, lack of necessary repairs, and neglected maintenance can lead to system failure and costly replacement. There is even the possibility of terrible consequences, in cases of carbon monoxide leakage. Protect your comfort, safety, and investment with a maintenance plan from Joseph Frederick & Sons. Through regular safety checks, comprehensive cleaning, and overall troubleshooting, we maintain ideal efficiency and ensure smooth and lasting operation.

Carrier gas and oil fired boilers are the perfect heating source for a radiant system. Radiant systems offer up to a 40% savings over traditional heating systems. Consider that water is denser than air and can transport 3,200 times more heat per cubic foot. It can circulate slowly, evenly, and silently, providing efficient and consistent warmth without the noise, draft, and dust of forced air systems. Enjoy a perfect blanket of heat, right where you’ll enjoy it most. If you are interested in learning more about the many benefits of radiant heat, contact the experts from Joseph Frederick & Sons.
