Hot Water Systems Sydney

Cold shower this morning? We repair, replace and install every type of hot water system across Sydney - gas, electric, solar and heat pump - often on the same day.

If you have no hot water, the most common causes are a failed heating element or thermostat (electric), a pilot light or gas valve issue (gas), or a tank that has reached the end of its life. A licensed plumber can usually repair the system the same day, or supply and install a new gas, electric, solar or heat pump system. Jetstar services all Sydney suburbs 24/7.

Repair or replace - we'll give you the honest answer

When your hot water goes cold, the first question is always the same: fix it or replace it? We give you a straight answer based on the age of the unit, the fault, and what it’ll cost you over the next few years – not what’s easiest for us.

We work on all major brands and every system type, so whether it’s a quick thermostat swap or a full changeover to a more efficient heat pump, you’re dealing with a plumber who has seen it all across Sydney.

Signs your hot water system is failing

A dying hot water system usually warns you first. Watch for these before it fails completely:

Water runs lukewarm or goes cold quickly
Rusty, discoloured or smelly hot water
Water pooling or dripping around the tank
Banging, popping or rumbling noises from the unit
The system is more than 8–12 years old
Rising energy bills with no change in use

Clear steps from your first call to hot water flowing again.

Gas vs electric vs solar vs heat pump hot water

Choosing a new system? Here’s how the four main types compare for a typical Sydney home.

System type	Upfront cost	Running cost	Best for
Gas (continuous-flow)	Low–medium	Low–medium	Homes with mains gas; endless hot water
Electric storage	Lowest	Higher (or lower on off-peak)	Budget upfront; small households
Solar	Higher	Very low	Sunny roofs; long-term savings
Heat pump	Medium–high	Lowest running of the electric options	Cutting bills; government rebates available

Heat pump and solar systems may qualify for government rebates — we'll help you check your eligibility. Guide only; every home is different.

How much does a hot water system cost?

A repair is often the cheapest path if your system is under about eight years old. A new system varies widely by type and size – electric storage sits at the lower end, while solar and heat pump systems cost more upfront but save the most over time.

Frequently asked questions

My hot water stopped working - can you fix it today?

Usually, yes. Many faults like a tripped thermostat, pilot light or faulty element can be repaired same-day. Call 02 9073 4415 and we’ll get a plumber to you fast, day or night.

Should I repair or replace my hot water system?

As a rule of thumb, if your system is under 8 years old and the fault is minor, repair is worth it. Older units that leak or fail repeatedly are usually cheaper to replace, especially with a more efficient model.

Which hot water system is cheapest to run?

Heat pump and solar systems have the lowest running costs, though they cost more upfront. Gas continuous-flow is a strong middle option. We’ll match the right system to your home and budget.

How long do hot water systems last?

Most storage systems last 8–12 years, and continuous-flow gas units can last longer with servicing. If yours is in that range and playing up, it’s worth planning a replacement.

Are there rebates for efficient hot water systems?

Yes – heat pump and solar systems often qualify for government incentives. See Energy NSW for current NSW programs, and we’ll help you check what applies to your install.

Do you install continuous-flow gas systems?

We do. Our licensed gas fitters install and certify continuous-flow (instantaneous) and storage gas systems, giving you endless hot water without a bulky tank.
