Benefits Of Owning A Rinnai R75LSi

Runs on Natural Gas or Propane
As compared to oil and coal, natural gas is the cleanest fossil fuel in terms of emission, with the least emissions in terms of sulphur dioxide and nitrogen oxides, with virtually no ash or particulate matter released. Propane is also earmarked to be a viable alternative fuel source.
Both fuel sources release lower levels of carbon dioxide, carbon monoxide, and other reactive hydrocarbons as compared to oil and coal therefore will have a lesser impact on the environment.

Installing this tankless water heater also qualifies you for 300 USD under the non-property energy property tax credits. It also meets California and Texas NOx emissions standards. This applies to all Rinnai tankless water heaters except for Rinnai R98LS.
