Brand hub
Takagi is a tankless water-heater manufacturer whose official catalogue contains no dedicated boiler products: its T-H3 family officially supports space-heating and hydronic applications, but Takagi sells no boiler line of its own, so Boilers.ca documents its commercial tankless water heaters as DHW-only series rather than boiler hubs.

Where ROMA provides on-site service
On-site service is currently offered in Greater Vancouver, BC, including Vancouver, Burnaby, Richmond, Surrey, Coquitlam, North Vancouver, West Vancouver, New Westminster, Port Coquitlam, Port Moody, Delta, Langley, Maple Ridge, Abbotsford, Chilliwack, White Rock, Pitt Meadows, Tsawwassen, Anmore, Lions Bay, Belcarra, Bowen Island, Mission. Everything else on this site is reference information you can use anywhere in Canada.
Takagi's official site (takagi.com) sells tankless water heaters only: the T-H3 family (T-H3-DV-N/P indoor and T-H3-OS-N/P outdoor units plus T-H3S, T-H3J and T-H3M variants), the TCT-199 commercial tankless (indoor and outdoor), the TK-series residential units, and multi-unit rack systems. No dedicated boiler or boiler-line product exists in the catalogue. The T-M32 and T-M50 appear only as specification-sheet entries on the official support page: their linked PDF returns a 404 today and no archived official copy could be retrieved, so no T-M series or model records are published.
Takagi's official T-H3 page documents space-heating application: the T-H3-DV-N 'is well suited for residential/commercial applications such as small restaurants and beauty salons… Utilizing commercial grade copper alloy for the heat exchanger tubing, the T-H3 is also suitable for heavier residential usages such as space heating or domestic recirculation systems', and 'supplies hot water to domestic hot water systems (directly or indirectly) which can be used with storage tanks, recirculation systems, hydronic heating systems, radiant floor systems, and/or domestic & heating applications'. In other words, Takagi officially supports hydronic use of a tankless water heater without selling a boiler.
Because boilers.ca documents boilers, Takagi is recorded here at brand level with those official quotes, and its two commercial tankless families are documented as DHW-only series: the T-H3 Series (16 models from the official TRGSS01512 and TRGSS01713 spec sheets) and the TCT-199 Commercial Series (four models from TCGSS00117). No Canadian statement was found on the captured pages.

Error codes and alerts
Documented meanings resolved against the specific series, controller and manual version. A code is not a diagnosis.
Manuals and documents
Links go to the manufacturer's own documents. Boilers.ca does not reproduce manuals.
No dedicated boiler products appear in Takagi's official catalogue — it sells tankless water heaters. The T-H3 family is officially documented for space-heating, hydronic and radiant applications as a water heater, not a boiler.
Takagi's official T-H3 page states the unit is suitable for heavier residential usages such as space heating, and that it can supply hydronic heating systems and radiant floor systems — integration and design work still belongs with a licensed contractor.
The T-M32 and T-M50 are not in the current takagi.com product catalogue. The official specification-sheets page still lists them, but their linked PDF (media/19474/TCGSS00314.pdf) returns a 404 and no archived official copy was retrievable, so Boilers.ca does not publish T-M32/T-M50 records.
The T-H3 Series (T-H3, T-H3S, T-H3J and T-H3M in indoor and outdoor, natural-gas and propane versions) and the TCT-199 Commercial Series, both as DHW-only tankless water heaters with model rows taken from Takagi's official specification sheets.
