Burnham’s CarefreeTM line of boilers offers 100% fuel efficient electric heat in a smartly styled wall-hung
unit. The Carefree boiler combines the convenience of electric heat with the comfort that only a hydronic
system can provide.
The Carefree comes equipped with brand name quality controls, and all electric components are UL listed.
The one-piece cast iron construction provides dependable, long-lasting heat, and the heat exchanger is
covered by Burnham’s Lifetime True-Blue Limited Warranty. A large 3.5 gallon water capacity allows maximum heat extraction, and the heating elements are designed for years of trouble-free operation. The simple,
solid construction of this electric boiler makes it truly "carefree".
Conveniently available in three capacities ranging from 41,000 through 68,000 BTU/HR, the Carefree
boiler can meet your electric hydronic heating needs.

Note: DOE Heating Capacity ratings are shown. Where the boiler and piping are in the heated space, the boiler may be selected on the basis of the
Heating Capacity. Where a piping loss and/or pick up loss will exist, add this loss to the building loss to determine the total heating requirement.
Where a piping loss only will exist but cannot be calculated, multiply the calculated building loss by a 1.15 factor to determine the total heating
requirement. Design Working Pressure: 30 PSIG, Water Only.
