Takagi T-H3-DV-P Indoor Condensing Tankless Water Heater (Propane) Review

The Takagi T-H3-DV-P is an indoor condensing tankless water heater configured for propane. "T-H3" identifies the 199K BTU condensing platform; "DV-P" means direct-vent propane.

Specs: 199,000 BTU propane input, UEF 0.95 condensing, 9.8 GPM at a 35°F rise, dual stainless heat exchanger, PVC condensing venting. 15-year warranty on heat exchanger.

The propane configuration adds typical $200-$400 premium over the natural gas equivalent. The T-H3 platform shares engineering with Rheem RTGH series.

About $2,200 unit, $4,200 installed for propane retrofit including LP regulator upsizing if needed. Right buyer: rural propane home wanting Takagi/Rheem engineering at 199K BTU capacity.

Pros
  • On-demand operation at 10 GPM — no standby heat loss; unlimited hot water if demand is within flow-rate capacity
  • Strong UEF 0.94 efficiency — approximately 20% lower annual operating cost vs 0.62 standard
  • 15-year warranty — top-tier coverage for residential water heaters
  • High 10 GPM output — serves 3+ simultaneous hot-water fixtures in most US climates
Cons
  • Requires dedicated 199K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
