About the EFT Combi (discontinued)

HTP's retired EFT Combi pages document a combination appliance that provides both space heating and domestic hot water. The wall page prints 'up to a 95.1% AFUE' with EFTC-140W at 28,000-140,000 DHW/28,000-140,000 CH and 95.0% AFUE and EFTC-199W at 19,000-199,000 DHW/19,000-140,000 CH and 95.1%; the floor page prints 'up to 95.7% efficient' with EFTC-140F at 28,000-140,000/28,000-140,000 and 93.2% and EFTC-199F at 19,000-199,000/19,000-140,000 and 95.7%.

The LP-520 (wall) and LP-496 (floor) technical tables supply the model-record rows: CH inputs, DHW flows of 7.1/5.5/3.2 GPM on the 140 and 9.9/7.7/4.8 GPM on the 199 at 35/45/77°F rises, shipping weights (110/120 lb wall, 250/260 lb floor), dimensions, 1" NPT CH and 3/4" NPT DHW connections, 12-30 PSI CH and 150 PSI DHW pressures, and 2" (50 ft) or 3" (100 ft) venting. Both pages note 316L stainless steel heat exchangers, burners and tank, ENERGY STAR certification, low-NOx emissions, a 10 to 1 turndown on the 199 (5 to 1 on the 140) and a stainless steel indirect storage tank.

The EFT Combination Boiler (floor and wall) is listed on HTP's discontinued-products index; the retired pages and manuals remain for support. Boilers.ca records the line with productStatus 'discontinued' and canadianStatus 'unknown'; no official Canadian sales statement was found. Gas and combustion work belongs with a licensed contractor against the model's own manual.
