When You Need A New Hot Water System
Recognise the signs that it's time to upgrade or install a new hot water system for your Sydney property.
System Too Old
Hot water systems over 10-12 years old become inefficient and unreliable. Replace before catastrophic failure to avoid emergency costs and water damage.
Leaks & Corrosion
Rust-coloured water, pooling around the unit, or visible corrosion indicate tank failure. Installation of a new system is more cost-effective than repairs.
New Construction
New homes, granny flats, or extensions require properly sized hot water systems installed during the build phase. We coordinate with builders for seamless rough-ins.
Renovation Upgrades
Kitchen or bathroom renovations are ideal times to upgrade to energy-efficient systems. We integrate installations with your renovation timeline.
Insufficient Capacity
Running out of hot water during showers or with multiple taps in use? Your household has outgrown the current system—time to upsize.
Energy Efficiency Goals
Switch to solar or heat pump systems to slash energy bills by up to 75%. Access government rebates and reduce your carbon footprint.
Our Professional Installation Process
From initial consultation to final handover, we manage every step to ensure a smooth, compliant, and stress-free installation.
Property Assessment & System Design
Our licensed plumbers visit your property to assess existing services (water pressure, electrical supply, gas connection), measure available space, and review usage patterns. We consider household size, simultaneous usage, solar access (for solar systems), and energy goals to recommend the optimal system type and size.
Calculate daily litres needed based on household size
Ensure adequate clearances and ventilation
Check electrical capacity or gas supply adequacy
System Selection & Quote
We present 2-3 system options with detailed specifications, upfront pricing (supply + installation), energy star ratings, estimated running costs, and warranty terms. Every quote includes rebate eligibility information, payback period calculations for efficient systems, and compliance certifications. No hidden fees.
- Unit supply (Rheem, Dux, Rinnai, Bosch, etc.)
- Licensed plumber & electrician labour
- All fittings, pipes, and connection materials
- Tempering valve & safety devices
- Old unit removal & disposal
- Compliance certificates & warranty registration
Pre-Installation Preparation
Once you approve the quote, we order your system from our trusted suppliers (usually 1-3 day delivery for standard models). Our team confirms the installation appointment, advises on any required access or preparation, and arranges electrician attendance if electrical work is needed.
Old Unit Removal & Site Preparation
On installation day, we isolate water and energy supply, safely drain and disconnect the old system, and remove it from your property. We lay drop sheets to protect flooring, clear the installation area, and prepare mounting points or plinths for the new unit. Solar and heat pump systems may require roof mounting or outdoor unit placement.
New System Installation & Connection
We position and securely mount the new hot water system, connect cold water inlet and hot water outlet pipes, install pressure & temperature relief valves, and fit tempering valves to comply with AS 3500.4. Licensed electricians connect electric or heat pump systems; gas fitters connect gas continuous flow or storage units with leak testing. Solar systems include roof panel mounting and glycol line connection.
- • Cold water inlet with isolation valve
- • Hot water outlet with expansion control
- • Tempering valve set to 50°C
- • PTR valve with drain line to safe discharge
- • Dedicated circuit with safety switch
- • Gas line pressure testing (gas units)
- • Flue installation & termination (gas units)
- • Control wiring for solar/heat pump systems
Testing, Commissioning & Handover
We pressure test all connections, fill and heat the system, calibrate temperature settings, test safety valves, and verify proper operation. You'll receive a full demonstration of controls, maintenance schedules, and warranty information. We issue compliance certificates (plumbing Certificate of Compliance, electrical Certificate of Compliance for electrical work, gas Certificate of Compliance for gas work), and register manufacturer warranties on your behalf.
- Plumbing compliance certificate
- Electrical certificate (if applicable)
- Gas certificate (if applicable)
