Replacement

When installing new hot water systems, our team provides cost-effective solutions to ensure you get reliable and efficient hot water without overspending.

Scheduled servicing

Periodic maintenance, including hot water maintenance, extends system lifespan and keeps running costs down. We flush tanks, test TPR valves, check anodes and verify temperatures and pressures.

Emergency response

No hot water? Leak at the tank? We provide same-day service and hot water service for urgent repairs, with after-hours callouts across the Coast. Our day service is available for both installation and repairs to ensure your hot water needs are met promptly.

Safety & warranty

Licensed installation ensures your system runs safely, keeps your family protected, and maintains the manufacturer’s warranty. Modern systems include temperature/pressure relief and scald protection—critical for compliance. We’re familiar with brand warranties and can advise on coverage and claims.

Choosing the right unit

The best option depends on household size, usage patterns, energy source and space. When selecting the right water heater or hot water unit for your needs, consider factors such as installation requirements, energy efficiency, and ongoing maintenance. As a guide:

  • Capacity: Storage systems typically allow ~30–40 L per person (gas) or ~55–60 L per person (electric).
  • Instantaneous: Delivers continuous flow sized to simultaneous outlets (e.g., shower + sink).
  • Running costs: Heat pump and solar usually win long-term; gas hot water units often beat electric storage on tariffs, as they are less expensive to run compared to electric systems.


We’ll assess your property and recommend a setup that balances upfront cost, efficiency and comfort, including options like gas, electric, solar, heat pump water heaters, and tankless hot water heaters.

Sizing matters

Too small = cold showers; too large = wasted energy. Our team sizes your system based on peak demand, bathroom count, flow rates and water temperature rise. The result: steady supply without bill shock.

System types (we install & service)

  • Gas (storage & instantaneous): Consistent performance and fast recovery. Great where natural gas is available. Gas storage systems are ideal for households of varying sizes, as they can be sized to meet specific hot water demands efficiently.
  • Electric (storage & tankless): Straightforward install, popular for smaller spaces or off-gas properties. Electric systems are known for their energy efficiency and are available in both traditional electric hot water systems and tankless systems. Tankless systems offer long-lasting, space-saving solutions, while modern electric hot water system options provide reliable hot water for residential needs.
  • Solar (with gas/electric boost): Use roof collectors to cut bills and emissions.
  • Heat pump: High efficiency by extracting warmth from the air—ideal for energy-conscious households.

Pricing & efficiency

  • Indicative unit costs: From entry-level electric storage through to premium solar/heat pump solutions, we provide cost-effective solutions for all budgets.
  • Total cost of ownership: We consider installation, rebates (where available) and running costs.
  • Efficiency tips: Choose high star-rated models, insulate pipework where appropriate and service regularly.

Case study: Gosford same-day changeover

A 12-year-old electric unit failed in the morning. We attended promptly, delivering our expert service by confirming a failed element and age-related corrosion, and recommended a replacement. By afternoon, the customer had a new hot water system installed—a high-efficiency gas continuous-flow unit was installed and commissioned—hot showers back that night and lower ongoing costs.

We provided tailored hot water solutions to ensure the customer’s needs were fully met.

FAQs

How long does a system last?

Typically 8–12 years depending on type, water quality and maintenance.

Can you repair rather than replace?

Often, yes—especially on newer units. We’ll quote both options if the repair is viable.

What’s the best option for my home?

It depends on household size, available energy source and budget. We’ll recommend a shortlist after a quick assessment.

Do you do same-day changeovers?

In most cases, yes—stock and scheduling permitting.

Do you handle gas work?

Absolutely—our team includes licensed gas fitters.

Can solar panels be used for water heating?

Yes, solar panels can be used in solar hot water systems to provide efficient water heating. This renewable energy solution can lower energy bills, reduce environmental impact, and may qualify for government incentives. Solar water heating is a cost-effective option for both homes and businesses.
