Vesta and the Consumer Products Safety Commission have announced a recall of its VST gas-fired tankless water heaters. The exhaust duct can crack, allowing gases to escape inside of the home, posing a carbon monoxide (CO) poisoning hazard that can result in death or serious injury.
Vesta has received 33 reports of cracked exhaust ducts allowing exhaust fumes to leak out. No injuries have been reported.
Consumers should immediately stop using the recalled water heater and contact VESTA.DS to have a certified technician install the free repair. The Vesta recall support page can be found at https://www.vestahws.com/?act=info.recall&ch=support.
