Takagi T-H3-DV-P in practice
Per Takagi's official specification sheet (TRGSS01512), the T-H3-DV-P fires from 13,000 to 199,000 BTU/h on propane, is rated 0.93 UEF, and delivers up to 10 GPM maximum flow. It connects on 3/4" NPT hot/cold water lines and a 3/4" NPT gas line, measures 23-5/8 × 17-3/4 × 11-1/4 in and has an approximate shipping weight of 71 lb.
The T-H3-DV-P is an indoor model with a commercial-grade copper primary heat exchanger and a Type 316L stainless-steel secondary exchanger, Ultra-Low NOx combustion below 14 ng/J (< 20 ppm), and power direct venting on PVC, CPVC or ABS (3" to 70 ft or 4" to 100 ft). It ships with an integrated temperature controller on indoor models and a wall-mount remote controller on outdoor models.
Takagi's official T-H3 page documents the family for space-heating, hydronic and radiant applications as a water heater; it is not a boiler. Sizing, venting design, gas-supply capacity and any hydronic or recirculation integration are engineering decisions that belong with a licensed contractor following the current installation manual and local code; Boilers.ca reproduces Takagi's printed figures and does not size appliances from floor area.
Best suited to
- Indoor domestic hot-water service at up to 199,000 BTU/h input
- Projects needing 0.93 UEF condensing efficiency with Ultra-Low NOx combustion
- Manifolded systems: Easy-Link up to 4 units, or Multi-Link up to 20 with a controller

Frequently asked questions
Is the Takagi T-H3-DV-P a boiler?
No. It is a condensing tankless water heater (DHW-only). Takagi's catalogue contains no boiler line; where the T-H3 family is used with hydronic or radiant systems, the appliance is still a water heater and the system must be designed by a licensed contractor.
What is the input range of the T-H3-DV-P?
Takagi's specification sheet prints 13,000 BTU/h minimum and 199,000 BTU/h maximum input on propane, with up to 10 GPM maximum flow and 0.93 UEF.
Can the T-H3-DV-P be used for space heating?
Takagi's official T-H3 page states the unit can supply hydronic heating systems and radiant floor systems, and that it suits heavier residential usages such as space heating. That is an application of a water heater; a licensed contractor must confirm the design against the installation manual and code.
