On October 29, 2026, the U.S. Consumer Product Safety Commission (CPSC) announced a recall of NTI and HTP brand residential gas boilers manufactured by Ariston, formerly NTI Boilers. About 4,726 units were sold in the United States, plus 2,261 in Canada. (CPSC)
What the hazard is
According to CPSC, the condensate dish inside the boiler can crack during a delayed ignition. That allows unburned gas to build up inside the sealed cabinet. If the gas ignites, the front cover can suddenly detach, creating a risk of serious injury or death from fire, carbon monoxide (CO) poisoning, and impact.
The firm has received 34 reports of the condensate dish breaking, including three reports of the front cover detaching. In one incident, a technician servicing a boiler suffered a broken jaw.
Which boilers are affected
The recall covers NTI FTVN and TFTN series boilers (gray) and HTP EFTU, or Elite Fire Tube Ultra, boilers (black). Affected models are FTVN150, FTVN150C, FTVN199, FTVN199C, TFTN150, TFTN199, EFTU-150WBN, EFTU-150WCN, EFTU-199WBN, and EFTU-199WCN, but only within specific serial number ranges. The model and serial number are on the rating plate on the left-hand side of the boiler. Compare yours against the full serial table on the CPSC recall notice.
These boilers were sold through independent heating and plumbing contractors and wholesale distributors nationwide from May 2021 through July 2026, for about $3,200 to $7,700. If a contractor installed a high-efficiency gas boiler in your home during those years, it is worth checking the brand and model.
What to do
- Stop using a recalled boiler immediately.
- Contact Ariston to schedule a free repair by a certified technician: 800-688-2575 (7 a.m. to 8 p.m. ET, Monday through Friday), VCexchanger@ariston.com, or ntiboilers.com/safety-recalls.
- If you must keep using the boiler while you wait, CPSC says to have working smoke and carbon monoxide alarms in the home.
A practical heating-season reminder
Whatever brand of boiler or furnace you have, heating season is a good time to test smoke and CO alarms on every level of the home and outside sleeping areas, and to keep the area around heating equipment clear. If you smell gas, leave the home and call 911 and your gas utility from outside.
