Rinnai Boilers

When deciding between heat-only boilers and combination boilers, consider the added convenience of combination boilers, which provide both heating and hot water in a single unit. All boiler series are adaptable to either natural gas or propane, offering versatile fuel options. Notably, these boilers require less space compared to traditional models, making them ideal for effortless installations in both existing homes and new construction projects. They are low-maintenance units with stainless steel heat exchangers and repair, and parts are easily available, promoting optimal performance and energy efficiency. Rinnai tankless water heaters and boilers come with a 15-year heat exchanger warranty, a 5-year part warranty, and reasonable labour coverage of 1 year. You have the opportunity to extend this coverage to 5 years if you register the product within 90 days of your purchase.
