Triangle Tube Pro specialists. As Triangle Tube exits the market, we provide legacy support and replacement planning.
Hydroflow is a Triangle Tube Pro with extensive experience servicing the Prestige and Instinct boiler lines. As Triangle Tube transitions its business model, we are committed to providing expert support for existing installations across San Francisco and Marin County. Our technicians are trained to perform the required combustion analysis and maintenance to keep your legacy Triangle Tube system running safely and efficiently — and to give you an honest assessment of when replacement makes more financial sense than continued repair.
Triangle Tube experienced a major recall spanning multiple boiler models (Prestige, Solo, Excellence). Original manuals did not clearly specify required venting materials for high flue temperatures. PVC vents exposed to 140–150°F exhaust began breaking down — turning yellow or brown, then disintegrating — creating serious carbon monoxide leak risk. If you own a Triangle Tube boiler, three things matter: never skip annual maintenance (we check flue temperatures every visit), let us install the updated ignition recall kit if not already done, and ensure you have a carbon monoxide detector wired directly to your boiler as an automatic kill switch.
Mandatory annual service for Triangle Tube — opening and cleaning the fire tube heat exchanger, flue temperature measurement, combustion analysis, and recall kit installation.
Ignition kit recall updates, pressure sensor replacement, and error code diagnosis. We carry some common Triangle Tube parts — though heat exchangers are increasingly difficult to source.
When Triangle Tube parts become unavailable, replacement with a modern Lochinvar or Navien combi-boiler is often the smarter financial decision.
Expert legacy support, recall kit installation, and transparent replacement planning for Triangle Tube Prestige and Instinct owners.
