HTP EFTU-199WBN in practice
The EFTU-199WBN is a wall-hung heating-only condensing boiler of HTP's current Elite Fire Tube Ultra line — the code reads wall-hung (W), boiler (B), natural gas (N), with propane conversion kits included. It fires 19.9 to 199.0 MBH for central heating at 95% DOE AFUE with 184 MBH DOE heating capacity and a 160 MBH net AHRI water rating, weighing 131 lb shipping (139.5 lb full) with 2.8 gal of boiler water content.
It uses the SA-240-S43932 stainless steel vertical fire-tube heat exchanger (down-fired, ASME 'H') shared by the line, a 10:1 turndown, built-in ECM pump and the AristonThermo GALEVO2 control with LCD. The 199 model must be vented in 3" diameter pipe — exhaust runs 6–150 ft in 3" (6–100 ft in 2" where allowed) and the intake 0–150 ft in 3" (0–100 ft in 2" where allowed), in PVC, CPVC, polypropylene or stainless steel, as a Category IV sealed-combustion direct-vent appliance. CH supply/return are 1-1/4" male NPT, the indirect return 3/4" male NPT and the gas inlet 3/4" male NPT, so an indirect water heater connects to the boiler's own return port.
These are heating-only boiler models — domestic hot water comes from an indirect tank on the system, with the printed DHW indirect setpoint range of 97–149 °F. HTP backs the EFTU with a 15-year limited residential warranty when registered online. Boilers.ca records no official statement of Canadian sales, so canadianStatus stays 'unknown'; gas and combustion work belongs with a licensed contractor against LP-723 (Revision date 2.23.22).
Best suited to
- Homes whose heat-loss calculation fits inside 199 MBH of heating input
- Wall-hung boiler replacements with a separate indirect hot-water tank
- Installations that can vent in 3" pipe (mandatory on the 199)

Frequently asked questions
Is the EFTU-199WBN a combi boiler?
No — the WBN models are heating-only boilers. Domestic hot water is produced by an indirect tank connected to the boiler's 3/4" indirect return; HTP's combi models carry WCN codes.
What does the EFTU-199WBN weigh?
The official table prints a 131 lb shipping weight and a 139.5 lb approximate full boiler weight, with 2.8 gal of boiler water content.
Can the EFTU-199WBN vent in 2" pipe?
No. LP-723 states 199/199C models must be vented in 3" diameter pipe (exhaust 6–150 ft, intake 0–150 ft).
