Frequently Asked Questions

How much does a gas hot water system cost in Sydney?

Gas hot water system costs can vary depending on whether you need a repair, replacement, or new installation. On average, system installations in Sydney can range from budget-friendly options to premium models from trusted brands like Rheem, Rinnai, and Dux.
At In House Plumbing, we provide clear, upfront quotes before any work begins. You’ll know exactly what to expect, with no hidden fees or surprise add-ons—just honest pricing tailored to your home or business needs.

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

If your system is fairly new and the issue is minor, such as a faulty valve or pilot light, repairs may be the most cost-effective option. However, if your unit is older, leaking, or struggling to keep up with demand, replacement could save you money long-term.
Our licensed plumbers can inspect your system and provide straightforward advice. We’ll help you weigh up the repair versus replacement decision so you can choose the best solution for your family or business.

Can I get same-day hot water repairs near me?

Yes—you can. We offer same-day gas hot water service across northwest Sydney, including Bella Vista, Kellyville, Blacktown, Quakers Hill, and surrounding suburbs. Our vans are fully equipped to handle most repairs on the spot.
Just give us a call, and we’ll dispatch a licensed gas hot water plumber to your location. Our goal is to restore your hot water as quickly and safely as possible so you can get back to your day.

What’s the difference between gas and electric hot water systems?

Gas hot water systems typically heat water faster, are more energy-efficient for larger households, and continue working even during power outages. Electric systems are often cheaper to install upfront but may cost more to run long-term.
We can walk you through the pros and cons based on your household size, budget, and energy needs. Whether you’re considering gas, electric, or continuous flow, we’ll help you choose the right system for your property.

How do I know if my plumber is licensed for gas?

In NSW, plumbers must hold a gas fitting license to legally install, repair, or service gas appliances. Always ask for proof of licensing before booking a job.
At In House Plumbing, all our gas plumbers are fully licensed and insured. This means every job meets strict safety and compliance standards, giving you peace of mind that your system is in expert hands.
