Recall: Fireplace-Powered Water Heaters Warning

CPSC Warns of Explosion Hazard With Fireplace-Powered Water Heaters

Washington, D.C. --The U.S. Consumer Product Safety Commission today reissued a warning to consumers of a potential explosion hazard. with some fireplace-powered water heaters used to supplement home heating systems. With the end of winter approaching, the CPSC urges consumers who have these water heaters to have them checked for any possible repairs needed as a result of their recent use. It is also a good time to have safety devices installed.

At least thirteen explosion incidents reportedly associated with the failure of these devices have occurred since 1977, resulting in one death, seven serious injuries, and substantial property damages. Five of these explosion incidents have come to the Commission staff's attention after an alert about this hazard was first issued in November, 1982. The Commission urges anyone having a fireplace water heating unit to have it safety checked immediately.

The fireplace-powered water heaters are made of tubular steel or steel plate and resemble a fireplace grate or liner. Plumbing connects the unit to the water heating system of the home. When there is a fire in the fireplace, furnace heat is either supplemented or replaced entirely by heat generated through the fireplace.

Slowing or stopping the flow of water through the unit (resulting from circulator pump failure, electrical power failure, or frozen pipes) may result in water in the unit boiling into steam. If the unit does not have an adequate pressure relief device, properly installed, the build-up of pressure can cause an explosion.

CPSC urges consumers who have one of these units to have it safety-checked by a qualified, licensed plumber who has specific knowledge of boilers, water pumps, pipe freezing problems, and pressure relief valves.

Consumers may report incidents with a fireplace-powered water heater by calling the CPSC toll-free Hotline at 800-638-CPSC. A teletypewriter number for the hearing impaired is (301) 595-7054.
