T-H3 vs T-D2 (newer condensing)
T-D2 is the newer-generation condensing replacement. Slightly higher efficiency (0.95 vs 0.94 UEF), updated modulation logic. T-D2 is the better choice for new installs; T-H3 still sold for installer/parts continuity.
Pricing
- T-H3J-DV-N: $1,199-1,449
- T-H3-DV-N: $1,449-1,749 (flagship)
- T-H3-OS-N: $1,499-1,799 outdoor
- T-H3-DV-P: $1,599-1,899 propane
Bottom line
The volume Takagi flagship. For most homes choosing Takagi, T-H3-DV-N is the answer. Junior T-H3J for 1-2 bath. Outdoor for warm climates. Consider T-D2 for new installs if available.
