Series facts
The TK-540P Series is Takagi's condensing tankless water heater with an integrated recirculation pump, sold in indoor (TK-540P-NIH, -PIH) and outdoor (TK-540P-NEH, -PEH) models. The official specification sheet prints 15,000 BTU/h (NG) or 13,000 BTU/h (LP) minimum input and a 199,000 BTU/h maximum, with UEF of 0.93 indoors and 0.95 outdoors — the outdoor pair is ENERGY STAR qualified.
All four models share a 23-5/8" H × 17-3/4" W × 11-1/4" D cabinet, 3/4" NPT hot/cold water and gas connections, up to 10 GPM maximum flow and 15–150 PSI water pressure, with indoor models certified to 10,100 ft elevation and outdoor models to 6,000 ft. Indoor units include integrated temperature and pump controls with advanced diagnostics and a factory-installed power cord; outdoor units include a wall-mount temperature remote controller. Venting is power direct vent with 3" PVC to 70 ft or 4" PVC to 100 ft, and Easy-Link supports up to three other T-H3 units, with common venting up to 8 units.
The TK-540P is a water heater, not a boiler: it produces domestic hot water and has no hydronic heating circuit. The four product pages are live on takagi.com; the specification sheet prints the full rating table. Canadian availability is recorded as unknown because no Canadian statement appears on the captured pages.
