Carrier offers boilers through Sears as well as heating and cooling specialists. For a list of local dealers, visit the company's website. Carrier boilers work with baseboard heaters, radiators and floor-radiant heating systems.
As of 2015, Carrier offers two series of boilers, Comfort and Performance. Gas and oil boilers are available in the Performance series, while gas is the only option in the lower-priced Comfort series. Carrier provides a 10-year limited warranty on parts and a 20-year limited warranty for the heat exchanger on most boiler models. A few models only offer a 12- to 15-year warranty on the heat exchanger.
The cost of the boiler increases along with the energy efficiency. None of the boilers in the Comfort Series are Energy Star qualified, though the boilers in the Performance series are Energy Star-qualified in certain sizes. The Carrier Performance boilers are rated among the most efficient boilers of 2015 by Energy Star.
Carrier boilers work with a hydronic system to circulate hot water or steam through pipes that connect with radiators, radiant tubing or baseboard heaters. Boilers, which are more expensive than most other central heating systems, provide a more consistent and gentle heat. Unlike a forced-air system, a boiler does not transport allergens and dust throughout the home.
