Questions and answers
Check the controller for a code, the power outlet near the unit, and whether other gas appliances work. Then ring us with what you found, and leave the unit's cover on.
Yes. Continuous-flow units are most of the Rinnai work we do, along with Rinnai storage tanks. We diagnose from the code and test before replacing anything.
No. Rinnai is one of the brands we service and fit, not a company we act for. Warranty claims usually go through Rinnai directly.
It depends on which part has failed and how easy the unit is to reach. You get the price in writing after we've tested it, and there's a $0 call-out on any job you book with us.
Usually on the same visit. Common Rinnai units are carried for same-day swaps, and a like-for-like unit goes back on the same connections.
Usually it's not getting enough water flow or enough gas. A blocked inlet filter, a failing flow sensor or a gas pipe that can't feed the unit and the cooktop together are the common reasons.
