Repair or replace: how to decide for your hot water system
A practical appraisal of your system’s age, condition and recent faults tells us if a repair is sensible or if a new unit is better value.
Age, condition and warranty status
We start by noting the age of the current system and whether it still has warranty cover. Older units with repeated faults often cost more in downtime and parts than a modern, efficient unit.
Visible leaks and corrosion
We inspect for visible leaks, rusty discharge and tank corrosion. These signs commonly mean a storage tank is near end‑of‑life and carries higher failure risk.
Efficiency, bills and capacity
Rising bills can show reduced efficiency from scale, failing elements or burner issues. If your household has grown, the unit may no longer meet peak demand. A correctly sized continuous flow unit (about 26 L/min for many homes) or a larger storage heater can solve capacity problems.
Costs and technology trade‑offs
We compare upfront repair costs with total ownership costs. Storage systems have standing losses but are simple to service. Continuous flow, heat pump or solar options cut running costs but need higher initial spend. We give a clear, fixed‑price recommendation so you can choose what suits your needs, budget and timeline with confidence.

Choosing the right hot water system for your home or business
Selecting the right technology depends on household demand, site constraints and long‑term energy goals. We guide owners through pros and cons so you choose a right‑sized solution that balances performance, running costs and budget.
Storage tank systems: proven performance and sizing by demand
Storage heaters use gas burners or electric elements and suit steady, predictable demand. Good insulation reduces standing losses and makes off‑peak tariffs more attractive.
Continuous flow units: compact design and on‑demand heating
Continuous flow heats on demand and saves space. Common sizes range 12–32 L/min; we often specify 26 L/min for busy homes to cover multiple showers without loss of pressure.
Gas option for larger households
Gas units deliver efficient, reliable performance for bigger properties. Pairing a high‑star continuous flow unit with gas can lower energy use and meet peak demand with minimal storage.
Electric, solar and heat pump choices
We assess electric hot water where off‑peak electricity suits your tariff. Solar hot solutions can cut energy consumption by up to 65–90% depending on configuration.
Heat pumps operate like an air conditioner in reverse and typically save around two‑thirds of the energy used for heating. We evaluate noise, placement and ambient temperature impacts before recommending one.
- We size systems to peak demand and tariff options to keep running costs low.
- We specify unit capacity and fuel to match your layout and usage patterns.
- We recommend reputable brands such as Rheem, Rinnai, Dux, Vulcan, Aquamax and Bosch and commission every system correctly.
We tailor a mix of technology, capacity and fuel so you get consistent, efficient service from day one.
Installation, safety and commissioning you can trust
A detailed site check prevents surprises and ensures the new system fits your demand and plumbing constraints.
Site assessment, gas and electrical checks
We inspect your current system, gauge available gas and electricity supply, and measure water pressure. This shows any location limits and safe access needs.
Commissioning: pressure, burner and temperature
Our licensed team verifies gas inlet pressure, adjusts aeration and burner settings, and confirms delivery temperature. We fit and calibrate tempering valves to protect fixtures and users.

Costs and efficiency: what Melbourne property owners should consider
We weigh upfront purchase and installation against ongoing bills to show real value over time.
To make a sound choice you must compare total ownership costs: unit price, installation, commissioning, running costs and maintenance. We provide clear, itemised quotes so you can compare options on an apples‑to‑apples basis.
Running cost drivers across gas, electric, solar and heat pump
Gas 6‑star continuous flow often gives lower annual running costs than older gas storage units. Off‑peak electricity storage can be cheaper than continuous electric operation for some households.
Solar and heat pump options cut energy use substantially but have higher installation prices and longer payback periods. Your daily demand profile alters actual savings more than headline ratings.
Retrofitting, location and access factors that affect price
Retrofits can add cost when upgrading supply or rerouting plumbing. Converting from storage to continuous flow may require larger gas sizing or electrical work.
Site access and unit placement influence labour time. Positioning close to frequently used taps reduces wasted water and waiting time.
- We break down running costs across fuel types and tariffs.
- We review brands and warranty to ensure long‑term value.
- We show when repairs are sensible and when an upgrade pays back.
| Option | Typical install cost | Annual running | Payback notes |
|---|---|---|---|
| 6‑star continuous flow (gas) | $2,000–$4,000 | Low to medium | Often faster payback vs old storage |
| Electric storage (off‑peak) | $1,000–$2,500 | Low if off‑peak tariff | Good for simple installations |
| Heat pump / solar boosted | $4,000–$8,000+ | Very low | Higher install, long‑term savings |
