Hot water replacement
Hot Water System Replacement in Perth
When a hot water system fails, the decision is rarely just about the cheapest tank. We assess the existing installation, explain the options that genuinely fit your home, and quote in writing before any work starts.
In short: Replacing a hot water system means assessing what failed, confirming the energy source and installation position, sizing the new unit to the household, and installing it to current standards with compliant valves and clearances.
Signs your system needs replacing rather than repairing
Some faults are worth fixing and some are the end of the system. Water pooling under the unit almost always means internal tank corrosion, which cannot be repaired. Age, repair history and the cost of the repair against a new installation all feed into the decision.
- Water pooling beneath the tank or rust staining down the casing
- The system is beyond its expected service life and failing repeatedly
- Hot water runs out far sooner than it used to
- Repeated relief valve discharge that returns after replacement
- Repair cost approaching a meaningful share of a new installation
Choosing the right replacement system
The right system follows from the energy sources connected at the property, the space available, the number of occupants and when hot water is actually used. Gas storage and continuous flow suit homes with reticulated gas. Heat pump and electric storage suit all-electric homes, with heat pump offering substantially lower running costs where there is a suitable outdoor position.
How sizing is worked out
Storage systems are sized on volume and recovery rate. Continuous flow systems are sized on litres per minute at a given temperature rise. Sizing follows occupants, bathrooms and simultaneous outlet use — not the floor area of the house.
What a compliant installation includes
- Correct tempering or thermostatic mixing valve at the outlets it serves
- Pressure limiting and relief valves rated to the installation
- Correct clearances for flues, airflow and servicing access
- Properly supported and insulated pipework
- Safe tray and drain arrangements where required
- Testing and temperature checks at the outlets before we leave
What we need from you to quote
A photo of the existing system and its data plate, a photo of where it sits, and a short description of what is happening will usually get you an accurate picture of the options. Anything we cannot confirm from photos gets confirmed at the property before the work is scheduled.
