Frequently Asked Questions

How much does it cost to replace a hot water system in Sydney?

The hot water tank replacement price depends on the system type (gas, electric, or solar) and size. In Sydney, costs range from a few hundred dollars for small electric units up to several thousand for larger or more advanced solar systems. At In House Plumbing, we provide transparent quotes upfront so you’ll never face hidden fees.
We focus on long-term value rather than quick fixes. By installing premium systems and providing professional workmanship, we help you avoid breakdowns and unexpected costs down the line.

Do I need to replace or repair my hot water system?

constantly failing, replacement is usually the smarter choice. Rising energy bills, inconsistent water temperature, or visible tank corrosion are all signs it’s time for an upgrade.
Our team will always give you honest advice. If a repair is viable, we’ll explain your options. If not, we’ll recommend the best replacement system for your home or business needs, including trenchless pipe repair if underlying pipe issues are contributing to the problem.

Can you do same-day hot water system replacement?

Yes — in most cases we can provide same-day hot water system replacement Sydney-wide. Our plumbers carry common systems in stock and work with local suppliers to ensure fast turnaround.
We know how disruptive it is to go without hot water, so we prioritize urgent and emergency hot water replacement Sydney calls. Whether it’s a weekday, evening, or weekend, our licensed plumbers are ready to help.

What’s the lifespan of a new hot water system?

A new hot water system typically lasts between 8–15 years, depending on the type, water quality, and usage. Electric and gas systems tend to last closer to 10 years, while solar hot water systems often last longer with proper care.
We only install trusted brands such as Rheem, Dux, and Bosch, and all systems come with manufacturer warranties plus our workmanship guarantee. With regular servicing, your new system can deliver reliable hot water for many years.

Is gas or electric hot water replacement more cost-effective?

Electric systems are usually cheaper upfront and easier to install, but they can cost more to run long-term. Gas systems are often more energy-efficient and better suited to larger households, though installation may be more involved.
Our team can walk you through the pros and cons of each option. We also offer solar hot water system replacement and professional gas plumbers for customers looking for the most efficient long-term solution.
