The Carrier website features information on the company's numerous different models of residential and commercial oil-fired boilers, including the two commercial oil-fired boilers that are a part of the Carrier Comfort Series. Both of these boilers have an energy efficiency rating of 86 percent annual fuel utilization efficiency and have a heating capacity that ranges between 91,000 and 280,000 BTUs. MPO-IQ and MegaSteam both produce slightly smaller boilers, as each company sells one boiler with a heating capacity of 69,000 BTUs.
Lennox features only one model of oil-fired residential boiler on its website, which is considered a standard efficiency unit. In terms of its AFUE rating, the Lennox COWB3 oil-fired boiler does not perform quite as well as the Carrier Comfort models, as the Lennox model only has a rating of 85.2 percent AFUE.
Weil-McClain has a bit larger selection of oil-fired boilers than either Lennox or Carrier. The company's website lists four different models of residential oil-fired boilers. In addition, Weil-McClain also produces three models of commercial gas/oil-fired boilers.Learn more about Heating & Cooling
