"Hydrohearth," "Hydroplace," and "Aqua Grate" fireplace-powered water heaters
Description
Washington, D.C. - The U.S. Consumer Product Safety Commission today warned consumers of an explosion hazard with certain fireplace-powered water heaters used to supplement home heating systems. Units involved were sold under the brand names "Hydrohearth," "Hydroplace," and "Aqua Grate." Manufacturers of these units–Ridgeway Steel Fabricators, Inc. of Ridgeway, Pennsylvania and Shark Manufacturing Corporation of Greenlawn, New York–are no longer in business. These devices are made of tubular steel or steel plate and resemble a fireplace grate or liner. Plumbing connects the unit to the hot-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 its installation checked by a qualified, licensed plumber who has specific knowledge of boilers, water pumps, pipe freezing problems, and pressure relief valves. Of particular importance is the location, pressure rating, and flow capacity of the safety valve. If there is no safety valve, have one installed with a pressure rating and flow capacity suitable for any type of fire. The safety valve should be installed in the outlet piping as near to the unit as possible without risking damage due to overheating. It should be oriented according to the valve manufacturer's recommendation to avoid safety valve clogging. The outlet pipe from the unit to the safety valve should contain no valves or other restrictions. The safety valve should be checked periodically by triggering it to be sure that it will relieve pressure. This should be done with caution, by a knowledgeable person, to avoid hot water scalding. Other fireplace-powered water heaters that contain built-in safety devices such as burst disks, fusible plugs, or blowout plugs, are not subject to this warning. Information on the devices involved and what owners of these devices should do can be obtained by calling the Commission's toll-free Hotline at 800-638-CPSC.
Hazard
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.
Remedy Instructions
CPSC urges consumers who have one of these units to have its installation checked by a qualified, licensed plumber who has specific knowledge of boilers, water pumps, pipe freezing problems, and pressure relief valves. Of particular importance is the location, pressure rating, and flow capacity of the safety valve. If there is no safety valve, have one installed with a pressure rating and flow capacity suitable for any type of fire.

Frequently Asked Questions
Follow the consumer action instructions in the recall notice above. Most recalls require you to stop using the product and contact the manufacturer directly, either by calling the toll-free number listed in the official CPSC notice or by visiting the manufacturer's website. You generally do not need a receipt or original packaging to claim a remedy. The manufacturer is legally required to provide the remedy (Inspect) at no cost to you.
No, you should stop using the product entirely, not just unplug it. Electric shock and fire hazards in recalled electrical products often involve internal wiring defects, faulty components, or insulation failures that can cause harm even after the product has been off for a period of time. Do not attempt to repair the product yourself. Keep it unplugged and stored safely until you receive the manufacturer's remedy. If the product has already shown signs of overheating, sparking, or discoloration, handle it carefully and consider contacting your local fire department for guidance on safe disposal.
In most cases, no. CPSC-coordinated recall remedies are designed to be accessible without proof of purchase. Manufacturers typically ask consumers to self-certify ownership and may ask for photos of the product or its serial number. Some manufacturers request that you mail in a portion of the product (such as a cut cord or removed component) as proof of disposal. Check the specific remedy instructions for this recall for exact requirements. If you registered your product at the time of purchase, the process is usually even simpler.
If the original manufacturer has gone out of business, the recall remedy may no longer be available through them. In this case, contact CPSC directly at 1-800-638-2772 or cpsc.gov for guidance. If the brand was acquired by another company, the acquiring company may have assumed recall obligations. In some cases where a remedy is unavailable, CPSC advises consumers to safely dispose of the product. If you were injured by the product of a defunct company, consult a product liability attorney, parent companies, distributors, and retailers may still bear liability in some circumstances.
