Overview
Heating water only when a tap opens, this Rinnai condensing unit replaces a storage tank with a wall-mounted heater that supplies the whole house. Circ-Logic can run an external pump on a schedule or on demand to cut the wait for hot water.
High flow and condensing efficiency let a large household run showers and appliances together with less gas. It needs natural gas, indoor venting and a qualified installer, and the recirculation pump is a separate part.
Who it's for
Families with several bathrooms who run out of hot water with a tank. Homes on propane need the matching fuel version, and the maker advises a pro install.
Pros and cons
- High whole-home flow
- Very high efficiency rating
- Saves floor space
- Optional Wi-Fi monitoring

- Recirculation pump and Wi-Fi module extra
- Warranty terms conflict in listing
Performance notes
Heating only on demand avoids keeping a full tank hot, and the condensing design is what earns its high efficiency rating. Circ-Logic timing decides how quickly hot water reaches distant taps.
