Strategic Assessment
Hot Water Service Replacements
Every hot water system replacement should start with a detailed site assessment because correct sizing and siting drive long-term performance and efficiency. At 24/7 Hot Water on the Sunshine Coast, we measure existing demand profiles, inspect pipe runs and mounting locations, verify electrical supplies and check roof orientation for solar options.
We perform load calculations, consider recovery rate and standby losses, and match system type to household or commercial usage to avoid under-sized or over-specified units. We also identify any access, ventilation or structural constraints that affect installation method and regulatory compliance.
After finalising the specification we present clearly documented options with manufacturer data, compliance notes and a recommended timeline. Call us on 0438 247 247 to get started.

Commissioning & Handover
We manage the full replacement process from safe decommissioning of the old unit through to final commissioning and customer handover. We isolate services, install new mounts and connections using manufacturer torque and sealing standards, and integrate electrical or solar interfaces with the property’s existing systems.
Our commissioning routine also includes pressure and leak testing, thermostat and control calibration, and flow and recovery verification. We even remove and responsibly dispose of the old tank or unit.
We issue a concise job dossier showing serial numbers, test readings and installed component details, register equipment warranties where applicable and walk customers through safe operation and straightforward maintenance steps to preserve performance. Call us to arrange an assessment.

FAQs
Everything You Need To Know
How do I know when my hot water system needs replacing?
A system that struggles to heat water, leaks or produces discoloured or metallic-tasting water may be nearing the end of its service life. Frequent repairs, excessive noise or visible corrosion are further signs. Most systems last around 8–15 years depending on type, maintenance and water quality.
What is involved in replacing a hot water system?
Replacement begins with isolating and draining the old unit, then disconnecting plumbing and electrical or gas connections. The new system is installed to meet current regulations, connected to supply lines and tested for leaks, temperature accuracy and safety device function before being commissioned and certified for use.
Can I upgrade to a different type of hot water system?
Yes, most properties can upgrade to a different system type if compatible connections and space are available. Switching from electric to gas, solar or heat pump may require plumbing and electrical adjustments, venting or roof mounting considerations and compliance checks to ensure efficiency and safety standards are met.
