Installing a Rinnai tankless water heater requires a contractor with experience in electrical and plumbing issues. Each unit has an electronic igniter that starts the flame to heat the water when a home occupant opens the tap. The units heat using propane or natural gas. Installation by an individual without sufficient experience can lead to performance and operational issues.

If a homeowner has a Rinnai tankless water heater in a home using propane, and natural gas becomes available, the manufacturer offers a conversion kit. However, the contractor must contact Rinnai directly to order the kit. The company does not offer these kits to homeowners. Kits are also available to convert natural gas units to burn propane.

While Rinnai tankless water heaters come with a warranty, the manufacturer also offers an extended service plan. Under the extended service plan, the company sends a licensed service professional to the home any time the unit malfunctions.
