HTP Brand Residential Gas Boilers Recalled Due to Fire and Carbon Monoxide Hazards

HTP-brand ELU Elite Ultra boilers may fail to seal properly, allowing flames and gases to escape and posing fire and carbon monoxide poisoning hazards. No injuries have been reported, but consumers should stop using the recalled units immediately.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: No injuries or deaths have been reported. The hazard is a real mechanical defect (incorrect door studs preventing proper sealing), not theoretical. Since injury has not yet manifested, this qualifies as a high-risk-of-harm product matching Score 3 criteria.

Plain-English summary

This recall involves approximately 96 HTP-brand ELU Elite Ultra residential wall-mounted gas boilers with model numbers ELU-150WBN and ELU-199WBN, manufactured by NTI Boilers Inc. of Canada and imported by Ariston USA LLC. The boilers are black, approximately 20 inches wide and 34 inches tall, with model and serial numbers located on the rating plate on the left-hand side.

The boilers can fail to seal properly at the door due to incorrect burner door studs. When the door does not seal, flames and gases can escape, creating fire and carbon monoxide poisoning hazards that could result in serious injury or death.

The recalled boilers were sold nationwide through independent heating and plumbing contractors and wholesale distributors between October 2024 and February 2025, priced between $3,400 and $4,100. No injuries have been reported.

Consumers should immediately stop using the recalled boilers and contact HTP toll-free at 800-323-9651 (Monday-Friday, 7 a.m. to 8 p.m. ET), email [email protected], or visit https://htproducts.com/safety-notice.html to arrange for a certified technician to perform repairs at no cost. While waiting for repair, consumers should ensure working smoke and carbon monoxide alarms are in place.
