A review of Rinnai boilers utilizing condensing technology for combined whole-house space and water heating. Explore Rinnai condensing boilers features and advantages.
Rinnai condensing boilers are a cost-effective solution for homeowners who want to use only one heat source – gas, for both residential water and space heating. These gas boilers are designed small but powerful that can provide extra efficient heating and offer optimum comfort, economical, and convenient heating.
Rinnai boilers are designed with condensing technology to provide high efficient space heating (CH) and domestic water heating (DHW) in different home sizes.
The manufacturer offers two lines of condensing gas boilers; heat only and combination, available in both Rinnai I-series and M-series.
The heat only group is for space heating only, while combination boilers allow homeowners to get hot water and home heating from the same unit.
The I-series is used in situations where multi-zone heating is needed. By using multiple thermostats, homeowners can set different temperatures throughout the home.
The M-series uses a built-in controller for easy temperature control and navigation.
Due to their intuitive design, Rinnai boilers offer flexible installation using concentric and twin pipe venting with long runs (up to 150 ft.), saving you money and time.
The smallest condensing boilers from Rinnai come with the max. gas input of 60,000 (CH)/103,000 (DHW) BTU, while the largest one offers the maximum power of 160,000 (CH)/199,000 (DHW) BTU. All models are ultra-efficiency models with a high EF factor of over 90%, which makes them Energy Star qualified and eligible for tax credits and rebates.
Rinnai combination boilers are a perfect solution for homeowners who would like to use one unit for space (central) and domestic water heating and at the same time. They use two heat exchangers to heat water on demand. Since they don't need a storage tank to store hot water, they take up much less space, making them a better option for smaller homes where storage space is limited.
Heat only boilers use a system with different valves, sensors, and pumps to heat water for use in a hydronic system. They can also be paired with a water storage tank to heat domestic water. Those hot water tanks can store a lot of water which is always ready for distribution. Since they need more space, heat only boilers are mostly used in larger homes, where greater quantities of hot water are needed instantly.
As said before, there are two series you can choose from; Rinnai M-series and I-series both made as heat-only and combination boilers.
Due to their greater heating capacity and maximum flow rate, Rinnai boilers from the I-series are designed for larger homes and families with higher hot water demand. The Rinnai M-series is ideal for families with smaller hot water needs, houses, and apartments.
