Our Hot Water System Services
Hot Water Replacement
If your tank has burst, rusted through, or is over 10–15 years old, a repair might not be the most cost-effective choice. We offer seamless hot water system replacement, and will guide you through selecting the best size and brand for your household’s water usage and budget.
Hot Water System Repairs
Is your pilot light constantly going out? Water running dangerously hot or too cold? We carry a wide range of spare parts in our vans for rapid, on-the-spot repairs. We troubleshoot thermostats, elements, valves and leaks to get your system back to perfect working order.
Hot Water Servicing & Maintenance
Prevention is always better (and cheaper) than a middle-of-the-night emergency. Regular servicing extends the lifespan of your unit, maintains efficiency, and keeps your manufacturer’s warranty valid. We recommend a check-up every 2 to 3 years to replace sacrificial anodes and test pressure relief valves.
New Hot Water Installation
Need to install a new hot water system? We offer seamless new hot water installation across the Hunter Region, guiding you through the best size and brand for your household’s usage and budget, and ensuring a flawless installation.
We Repair and Install All Types of Hot Water Systems
Gas Hot Water
Whether you rely on natural gas or LPG, gas systems offer fantastic recovery times. Our licenced gas fitters provide expert repairs and new continuous flow (instantaneous) installations, ensuring your system is 100% safe, compliant and efficient.
Electric Hot Water
Electric storage tanks are a staple in many Australian homes. From replacing burnt-out heating elements and faulty thermostats to full tank upgrades, we are the local specialists in electric hot water system repairs.
Solar Hot Water
Harness the power of the Aussie sun. If your solar booster is playing up or your roof panels and evacuated tubes need maintenance, our team provides comprehensive solar hot water repairs to keep your energy bills low.
Heat Pump Systems
Looking to slash your hot water running costs by up to 70%? Heat pumps pull warmth from the ambient air to heat your water. We specialise in premium heat pump installation and can advise on available government rebates.

Frequently Asked Questions
If your tank is leaking from the actual cylinder (not just a valve), or if the unit is over 12 years old and frequently breaking down, a full hot water system replacement is usually the safest and most economical option. For minor valve leaks or thermostat issues on newer tanks, a simple repair is normally all that’s required.
