Strata, Business & Commercial Hot Water Systems

We work with a range of commercial and shared hot water systems, including strata buildings, apartment blocks, shops, offices, childcare centres, hospitality venues and commercial properties. Our service focuses on identifying the cause of the issue and explaining suitable repair or replacement options.

Commercial Hot Water Diagnostics & Fault Finding

Commercial hot water faults can be caused by gas supply issues, electrical components, storage tank problems, circulation pumps, valves, controls, pipework or incorrect system operation. We carry out practical testing and fault finding to help determine what is causing the problem.

Repairs vs Replacement

Not every commercial hot water issue requires a full system replacement. Where possible, we aim to identify whether the fault can be repaired. If the system is unsafe, heavily corroded, undersized, unreliable or no longer economical to repair, we can provide replacement advice suited to the property and hot water demand.
