NTI and HTP residential gas boilers
Published October 29, 2026
What's the hazard
The condensate dish inside the boiler can crack during a delayed ignition, allowing unburned gas to build up inside the sealed cabinet. If the gas ignites, the front cover can suddenly detach, posing a risk of serious injury or death from fire, carbon monoxide (CO) poisoning, and impact hazards.
What to do
Consumers should stop using the recalled boilers immediately and contact Ariston to schedule a free repair by a certified technician. Consumers who must continue using the boiler while awaiting repair should have working smoke and carbon monoxide alarms in their homes.
