Hot Water
Commercial Hot Water System Upgrades Kings Cross
Restoring Hot Water to a 20-Unit Residential Complex in Kings Cross
When a centralised hot water system fails, it can impact all of the residents. That's exactly what happened when the team at Everyday Plumbing was called to a residential unit block in Kings Cross after all hot water services suddenly stopped working.
The building, which consisted of approximately 20 units, relied entirely on a centralised hot water system. With no hot water available throughout the complex, residents were understandably frustrated and required an urgent solution.
Our experienced Sydney plumbers attended the property on Good Friday during the Easter long weekend to investigate the cause of the failure and restore hot water as quickly as possible.
Diagnosing the Cause of the Hot Water Failure
Upon further inspection, our plumbers identified a major failure within the existing commercial hot water system. The heat exchanger had failed, letting water enter the system's electronic components.
As moisture spread throughout the electronics, the system completely broke down. The damaged electrical buttons and wiring no longer worked, preventing the unit from having access to hot water. Our team decided that a full replacement was the only way forward.
Emergency Temporary Hot Water Solution
As an immediate solution, we installed multiple electric hot water systems to create a temporary bypass arrangement. The system we needed was made to order, so it wasn't readily available. While not ideal as a long-term solution, these systems provided functional hot water to the building while we were waiting for the replacement equipment.
Removing the Existing Centralised Hot Water System
Once the new system arrived, our plumbers returned to the property a week later to complete the replacement. The project involved dismantling and removing the existing hot water infrastructure including:
- Failed Raypak heat exchanger
- Existing 430-litre hot water tank
- Associated pipework and components
- Damaged mechanical equipment
All of these components were removed manually by hand and safely removed down six flights of stairs.
Installing a New Commercial Hot Water System
We installed a brand new hot water system, designed to provide reliable hot water to all 20 units within the complex.
The installation included:
- New commercial hot water system
- New pipework throughout
- New circulation pumps
- Updated exhaust system
- System commissioning and testing
Our team made sure that every component was installed to the latest safety standard and thoroughly tested to ensure it is working properly and safely.
The Result
The new centralised hot water system meets the daily demands of residents while offering improved reliability and performance compared to the previous setup.
By responding quickly during the Easter long weekend and implementing a temporary hot water solution, Everyday Plumbing was able to minimise disruption and ensure residents were not left without hot water while waiting for the permanent replacement system.
