Rinnai's Infinity continuous flow units are a common sight on Darwin renovations and LPG homes. Our team carries common Rinnai parts for most repairs.
Rinnai has supplied gas appliances in Australia since 1971 and is best known for the Infinity continuous flow range.
Infinity heat exchangers commonly carry a longer warranty than the balance of the unit. Annual servicing and licensed installation are usually required for a claim.
Igniters, flame rods, water valves, filters and error-code diagnostics for Infinity units.
A well-installed Rinnai Infinity commonly runs 15–20 years, considerably longer than a storage tank, provided the inlet filter is kept clear and gas supply is correctly sized.

Typically a gas supply problem, a dirty igniter or a failed flame rod. On LPG homes out through Humpty Doo and Howard Springs it is often simply an empty or incorrectly changed-over bottle, which is worth ruling out before booking.
The unit lights then drops out. Usually gas pressure, a partially blocked burner, or a flue restriction on a unit fitted in a tight side passage.
Short bursts of cold mid-shower on older Infinity units. Frequently low flow through a clogged inlet filter or a mixer tap not drawing enough water to hold the burner on.
A genuine Darwin issue. Wet-season humidity, salt air and geckos or ants getting into the burner compartment cause more Infinity faults here than anything mechanical. Units on exposed coastal walls benefit from a sheltered position.
Heat exchanger failure on an out-of-warranty Infinity is the point where replacement usually wins; almost everything else — igniters, valves, sensors, filters — is economically repairable.
