Replacing an Old Gas Instantaneous Hot Water System
This customer in Burraneer contacted our hot water team after their existing Bosch instantaneous gas hot water system failed. The system was indoors, old, had developed reliability issues and replacement parts had become increasingly difficult to find. This made repairing it more expensive than it needed to be.
Assessing the Best Hot Water Replacement Option
Following an assessment, our team initially recommended replacing the Bosch unit with a new Rinnai internal gas instantaneous hot water system. However, the customer was concerned about the overall price. Internal gas units are considerably more expensive than their external counterparts due to their design and installation requirements. This increases the replacement cost by approximately 50%.
The customer asked if there was a more cost-effective alternative and we proposed installing an external Rinnai instantaneous hot water system on an exterior wall of the property. Although this required the installation of new hot water, cold water, and gas pipework, the overall cost remained significantly lower than replacing the system with another internal model.
The Installation Process
To achieve a neat and professional finish, the new services were routed internally through the garage before exiting to the external installation location. A licensed electrician installed a dedicated outdoor power supply to suit the new appliance, and the installation was completed in full compliance with the manufacturer’s requirements.
The customer was extremely pleased with the outcome. The completed installation provided a reliable, modern hot water system with neatly concealed pipework, while also delivering an estimated saving of approximately $2,000 compared with installing a new internal unit.
