HTP ELU-199WBN
The HTP ELU-199WBN is the 197 MBH-class wall-hung heating-only model of the Elite Ultra line: 19.7 to 197 MBH central-heating input (NG) with no internal DHW, recorded from the CH table printed on the official ELU page.

HTP ELU-199WBN in practice
The ELU-199WBN is a wall-hung heating-only unit of HTP's current Elite Ultra (ELU) line — the code reads wall-hung (W), boiler (B), natural gas (N) with liquid-propane conversion kits included. The official model table prints its central-heating input at 19.7 to 197 MBH (natural gas; the LP rows print 19.2 to 192 MBH) and a 'Heating Only' type with 'N/A' in the DHW column.
The page's XtraTech heat exchanger section describes a patent-pending durable stainless steel heating technology with a pipe surface up to 400% larger than conventional designs, and the page claims an 11:1 turndown and up to 96% thermal efficiency when the outdoor sensor is used. The model table itself prints no AFUE, weight or dimension rows, so none are recorded here; the model's installation and operation manual is doc 420010970305 (LP-700 Rev.000, 1.24.23) or 420011303900 (2.28.22) as grouped on the official documents page.
This model is one of the sizes the page says is available with a factory-installed floor-mount kit — 'just add FLKT to the model number when ordering' — so the wall record covers the ELU-150WBN-FLKT/ELU-199WBN-FLKT variants as the same unit. This record is current — the ELU line appears in HTP's current 'Elite Ultra Wall and Floor' navigation with the model table live. Boilers.ca found no official statement of Canadian sales on htproducts.com, so canadianStatus stays 'unknown'; gas and combustion work belongs with a licensed contractor against the model's own I&O manual.
Best suited to
- Homes whose heat-loss calculation fits inside 197 MBH of heating input
- Heating-only installs pairing the boiler with an indirect hot-water tank
- Projects that may want the factory floor-mount kit (add FLKT to the model number)

Frequently asked questions
Is the HTP ELU-199WBN a combi boiler?
No — the WBN code means wall-hung boiler (heating only): the official table lists its type as 'Heating Only' with N/A in the domestic hot water column, so DHW comes from an indirect tank or another appliance.
Does the ELU-199WBN have a floor version?
Yes — the 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'.
How is the ELU-199WBN fueled?
The official page states boiler and combi units ship as natural gas units and come standard with liquid propane conversion kits; on the 199 models the table prints separate NG and LP input rows.
