Rinnai Hot Water Repairs, Service and Installation in the Redlands and Brisbane Bayside

Dave Kiddy has more than 20 years on the tools as a licensed plumber and gas fitter, and every Rinnai job — from a service call to a full replacement — is done by him personally. He answers his own phone, quotes the job on site, and stands behind the work with our lifetime workmanship guarantee.

The Rinnai hot water range in general terms

Rinnai is best known in Australian homes for continuous flow gas hot water, and it is common to find a Rinnai unit mounted on an external wall of a home in Cleveland, Wynnum or further out toward Redland Bay, heating water on demand rather than storing it in a tank. Continuous flow suits households that want an endless supply of hot water without the standing losses of a storage tank, and it takes up less space, which matters on a smaller block or a townhouse. Rinnai also produces gas storage units for homes where continuous flow is not practical, along with heat pump hot water systems that use a compressor to draw ambient heat from the air rather than burning gas directly. We do not rank Rinnai above or below the other brands we work on — the right choice depends on your gas supply, household size and how the unit needs to be positioned on the property.

Common faults we see on Rinnai units

A large share of our Rinnai callouts involve a unit that has simply stopped heating, which on a continuous flow system can mean a fault with the ignition sequence, the gas supply to the unit, or the flow sensor that tells the unit hot water is being drawn. Ignition problems show up more often after a gas bottle change, a power outage, or when a unit has been sitting idle. Continuous flow units display an error code on the front panel when something is wrong, and that code is useful — but what it means depends on the model and the software version, so we check the code against the unit itself rather than assuming based on the number alone. On older Rinnai storage tanks we still see the same TPR valve leaks and tank corrosion that affect any storage unit, particularly on properties close to the water where salt air speeds up the process. Blocked or corroded flues and vents on gas units are another fault worth checking during a service, since they affect both performance and safety.

Repair or replace

We repair Rinnai units wherever the fault and the age of the unit make that the sensible option. When replacement is the better call, most residential hot water replacements land between $1,200 and $3,000 supplied and installed, depending on the unit type and size. If your Rinnai unit has failed outright and you need someone out urgently, most emergency jobs run $250 to $600 depending on what the repair involves. We give you that number before we start work, not after.

We also install and service other brands

Rinnai is one of six brands we work on across the Redlands. DK Plumbing also repairs, services and installs Rheem, Dux, Vulcan, Aquamax and Bosch systems, so a straight comparison or a like-for-like replacement is something we can talk through on the day.
