Frequently Asked Questions

How much does a hot water system cost in Sydney?

The cost of a hot water system in Sydney varies depending on the type of unit you choose—electric, gas, solar, or instant. Installation requirements and brand preferences also play a role. Basic systems are generally more affordable upfront, while energy-efficient models may save more in the long run.
At In House Plumbing, we provide clear, upfront pricing tailored to your needs. We’ll walk you through the options and help you choose a system that fits your budget without compromising on quality.

Is it cheaper to repair or replace my hot water system?

Repairing may be the right choice for newer systems with minor issues like a faulty thermostat or valve. However, if your unit is old, inefficient, or leaking, hot water system replacement may be the more cost-effective option.
Our plumbers will assess your system and explain whether repair or replacement makes better sense. You’ll always get honest advice, backed by a detailed quote, so you can make the decision with confidence.

What’s the best hot water system for a family home?

The right hot water system depends on your household size, water usage, and energy preferences. Larger families often benefit from continuous flow or solar systems, while smaller homes may prefer compact electric or gas storage units.
We’ll help you compare the benefits of each system and recommend trusted hot water system brands like Rheem, Rinnai, Bosch, and Dux. Our goal is to install a unit that delivers consistent hot water while keeping energy costs manageable.

Do plumbers offer same-day hot water installation?

Yes, at In House Plumbing we provide same-day installation and repairs across northwest Sydney. We understand how disruptive it is to go without hot water, which is why our team is ready to act quickly.
With fully stocked vehicles and access to a wide range of replacement units, we can often install or repair your system on the spot. That means less downtime for your household or business.

How do I know if my hot water system needs replacing?

Common signs that your hot water system may need replacing include rusty water, frequent leaks, inconsistent heating, or if the unit is more than 10–15 years old. Rising energy bills can also indicate an inefficient system.
Our licensed plumbers can inspect your unit and give you a clear recommendation. If replacement is necessary, we’ll help you choose an energy-efficient model and provide professional installation with minimal disruption.
