How long does a MSIG claim take?
A Rinnai tankless water heater or boiler warranty provides robust multi-tiered coverage, typically offering up to 10 to 12 years on the primary heat exchanger, 5 years on general parts and components, and a standard 1 year of coverage for labor. Homeowners can often secure extended labor protection or promotional warranty upgrades by officially registering their newly installed unit with Rinnai within specified early registration windows following professional installation.
