Frank Bros. installs a wide range of oil-fired boilers from European and American Manufacturers. We recommend the following brands:


Buderus boilers and controls are designed in Europe, where fuel costs are significantly higher than in the U.S. and environmental regulations are more stringent. Models like the G115 are constructed with the highest quality materials and designed to maximize the heating value of every ounce of fuel. The triple-pass design holds the gases in the boiler longer, allowing the cast iron to absorb the maximum amount of heat. A 3" jacket of thermal insulation encases the entire boiler block to reduce standby losses. When paired with the Logamatic control, a Buderus boiler can vary its output temperature to match the weather and avoid room temperature swings.



Peerless is one of world's leading manufacturers of cast-iron boilers, with a variety of models suitable for chimney venting or direct venting (without a chimney). Direct-vent models make great replacements for electric heating or heat pumps. High-efficiency models that achieve the ENERGY STARĀ® rating will reduce fuel consumption and save money. All Peerless boilers feature an insulated, enameled steel jacket that reduces heat loss.



Weil-McLain is a leading designer and manufacturer of oil-fired hot water and steam boilers for space heating in residential, commercial and institutional buildings. These systems often feature multiple flue outlets for complete venting flexibility and a recessed wall design for added protection. Their Ultra Boiler model received the ENERGY STARĀ® rating for achieving 87% annual fuel utilization efficiency.
