Gas Hot Water
Gas storage heats a cylinder using natural gas or LPG. Any gas assessment or work depends on suitable licensed contractor availability; no gas contractor is currently approved for this website.
Is gas right for you?

This is general information about gas hot water systems, not a contractor offer. No local contractor is currently approved; gas work is conditional on suitable licensed contractor availability.

What to know about gas hot water.
- Typical service life
- Broadly similar to electric storage, subject to water quality.
- Replacement time
- Usually a half day for a like-for-like gas storage swap.
- Common failures
- Pilot or ignition, thermocouple, gas control valve.
- Best fit
- Homes on natural gas with steady daily demand.
Gas storage recovers quickly, which suits larger households running showers back-to-back. Where the property is on LPG rather than reticulated gas, the running-cost picture changes, so it is worth comparing against electric or a heat pump before committing.
What to watch for
- A pilot that will not stay lit — commonly a thermocouple.
- Soot or scorching around the flue or burner area.
- If you smell gas, avoid electrical switches, leave the area and contact the gas supplier from a safe location.
Gas vs electric storage
How the two most common storage systems compare in real homes.
| Gas storage | Electric storage | |
|---|---|---|
| Availability | Needs natural gas at the property or LPG bottles | Works anywhere with a suitable circuit |
| Recovery | Reheats quickly after heavy use | Slower recovery, especially on off-peak |
| Running cost | Usually lower than electric on standard tariffs | Lower again on a dedicated off-peak tariff |
| Install work | Gas connection, flueing and clearances apply | Simplest like-for-like swap in most homes |
| Upfront cost | Generally higher than basic electric storage | Typically the lowest upfront option |
Still deciding? Read repair or replace and the replacement cost guide. A contractor must confirm scope, charges and suitability.

Gas Hot Water questions.
Is gas cheaper to run than electric?
+
On standard tariffs gas storage is usually cheaper to run than electric storage, but the comparison depends on your tariff, your usage and whether you are on natural gas or LPG.
What is the difference between natural gas and LPG?
+
Natural gas is reticulated to the property; LPG is delivered in bottles. Units are configured for one or the other, and running costs differ, so the right choice depends on what is available at your address.
Why has my gas system stopped heating?
+
Common causes are pilot or ignition failure, a failed thermocouple, gas supply issues, or a fault in the control valve. These are diagnosed on site rather than guessed at.
Can a gas storage system be installed indoors?
+
Some models are flued for indoor installation and others are outdoor-only. Clearances, flueing and ventilation all have to be right, which is why the model is chosen to suit the location rather than the other way around.
