Why heat pumps
A cleaner, lower-cost hot water upgrade for The Gardens homes
Heat pumps use electricity to move heat from air into water. That is why the running cost can be much lower than older electric storage systems.
Lower running costs
Heat pumps move heat from the air into water instead of generating heat directly.
Works day and night
Modern systems are designed to run in normal Darwin conditions, including cloudy weather.
Good solar partner
Timers and smart controls can help shift heating into cheaper daytime electricity windows.
Lower household emissions
A cleaner hot water upgrade when replacing older electric or gas systems.

System comparison
Heat pump vs electric, gas and solar hot water
The best system depends on household use, tariff, outdoor space, existing services and whether current incentives apply.
| System | Typical yearly cost | Notes |
|---|---|---|
| Old electric storage | $700-$1,000/year | Simple but power hungry, especially on peak tariffs. |
| Gas storage or instant | $450-$800/year | Depends on gas price, appliance age and household use. |
| Heat pump hot water | $200-$350/year | Efficient because it transfers heat rather than creating it directly. |
| Solar hot water | $150-$350/year | Can be efficient, but roof access, shading and booster cost matter. |

Maintenance tips
Protect efficiency after install day

Every 6 months
Check clear airflow, clean around the unit and make sure drainage is not blocked.
Every 12 months
Inspect valves, visible pipework, controller settings and signs of leaks or corrosion.
Every 5 years
Ask a licensed plumber about anode, valve and manufacturer service requirements.
Ongoing
Keep the outdoor unit away from bedrooms where possible and avoid enclosing the fan.
Local quote check
Compare the system, installation scope and final out-of-pocket cost.
