HTP's Elite Ultra (ELU) is the Italian-engineered wall-hung condensing boiler and combi line in the current 'Elite Ultra Wall and Floor' navigation: heating-only ELU-85/120/150/199WBN models and combi ELU-120/150/199WCN models, with FLKT floor-mount-kit versions of the 150 and 199 sizes. Boilers.ca models the seven wall units from the CH/DHW input ranges printed on the official model table.
Series facts
The product page states the boiler 'comes with an outdoor sensor that, when used, can provide up to 96% thermal efficiency' and prints an 11:1 turndown claim; the model table on the page prints no AFUE figure for any model.
The Elite Ultra (ELU) line is documented on HTP's official eliteultra.html page, whose heading reads 'Elite Ultra High Efficiency Condensing Boiler and Combi Units' and whose page copy says the boiler 'was co-designed by our Italian engineers'. It is one of the three families in HTP's current space-heating navigation — 'Elite Ultra Wall and Floor' — alongside the Elite Fire Tube Ultra (EFTU) and EFW lines, and the product page prints the full model table: heating-only ELU-85WBN (9,400/85,000 Btu/hr CH), ELU-120WBN (13,200/120,000), ELU-150WBN (15,000/150,000) and ELU-199WBN (NG 19,700/197,000, LP 19,200/192,000), and combis ELU-120WCN (CH 11,200/106,000; DHW 11,200/114,000), ELU-150WCN (CH 13,200/120,000; DHW 13,200/150,000) and ELU-199WCN (both sides NG 19,700/197,000 or LP 19,200/192,000).
Codes decode as wall-hung (W), boiler (B) or combi (C), and natural gas (N) with LP conversion kits included. The page notes that ELU-150WBN, ELU-199WBN and ELU-199WCN are also available with a factory-installed floor-mount kit — 'just add FLKT to the model number when ordering' — so the WBN/WCN wall records here cover the FLKT variants as the same unit. Two printed quirks are kept as printed: the ELU-120WCN table shows a DHW maximum (114,000 Btu/hr) higher than its CH maximum (106,000), and the 199 rows print separate NG and LP ranges.
The page claims an 11:1 turndown and 'up to 96% thermal efficiency' with the optional outdoor sensor, an XtraTech stainless steel (316L-class per the literature) heat exchanger, and a 15-year limited warranty when registered online; the model table itself prints no AFUE, weight or dimension rows, so none are recorded on the model pages. No official statement of Canadian sales appears on htproducts.com, so canadianStatus stays 'unknown'; gas work belongs with a licensed contractor against the model's own I&O manual (420010970305 / 420011303900).

Services for HTP boilers
Wall-hung (W), boiler (B) or combi (C), and natural gas (N) — ELU-85WBN is a heating-only boiler while ELU-120WCN is a combi that makes domestic hot water. Combi units are the WCN codes; all models ship natural-gas configured with liquid-propane conversion kits included.
The official page states ELU-150WBN, ELU-199WBN and ELU-199WCN 'are available with a factory installed floor mount kit. Just add FLKT to the model number when ordering.' Boilers.ca records the FLKT versions under the same wall models with the kit noted.
Current: it appears in HTP's current space-heating navigation ('Elite Ultra Wall and Floor') with its product page and model table live. The discontinued index lists HTP's older Elite FT, Elite Premier, Pioneer and Versa lines separately.
No official statement of Canadian sales or distribution was found on the official pages checked on September 9, 2026, so canadianStatus is recorded as 'unknown'. This hub documents the series for information and service planning.
