Overview
Not a storage tank heater, the Rinnai propane unit heats water only when a tap is opened and is built for outdoor installation. Scale detection watches for mineral buildup, and the listing notes Wi-Fi monitoring capability for checking on it remotely.
On-demand heating means no tank to reheat and no indoor floor space used, which suits homes running on propane. Flow is limited by the rated output, so a household running several showers at once should check its demand. Professional installation is recommended, and the warranty wording varies between sections of the listing.
Who it's for
Households on propane that want to free up the space a tank heater takes and can place the unit outdoors. Homes on natural gas, or where the heater must go inside, need a different model.
Pros and cons
- On-demand heating, no storage tank
- Outdoor install frees indoor space
- Scale detection helps protect the unit
- Wi-Fi monitoring capability mentioned
- Warranty terms conflict within the listing
- Professional installation recommended
- BTU input not listed
- Labor warranty shortens without registration
Performance notes
Delivered temperature depends on how much the burner must raise the incoming water at the flow being drawn, so colder inlet water reduces the flow available at a given setting. Scale detection flags mineral buildup that would otherwise cut heat transfer over time.
