Hot water system replacement and installation
Whether you are replacing an existing water heater or installing a system in a new home, renovation, apartment or commercial property, we can supply and install a solution suited to your requirements. We source a broad range of electric, gas, solar, instantaneous and heat pump hot water systems from leading manufacturers.
A hot water system may need to be replaced if the storage tank is leaking, the internal cylinder has corroded or the system is approaching the end of its expected service life. Replacement may also provide better value when parts are obsolete or unavailable, repair costs are high compared with the price of a new system or increasingly frequent faults make the system unreliable.
Upgrade to a larger water heater.
It may also be worth considering a new system if your existing water heater no longer meets your household’s hot water requirements, is incorrectly sized for the property or you want to upgrade to a more energy-efficient option.
Selecting a hot water system is not simply a matter of choosing a tank with a particular capacity. The best option for your property will depend on your household size, hot water usage, available energy sources, installation space, existing connections and budget.
Our specialists can assess these factors, explain the available options and recommend a system that provides reliable hot water without being unnecessarily large or expensive to operate. We can then supply the selected system and complete the installation, including any plumbing, electrical or gas work required.
Upgrade to an energy efficient hot water system
Improving energy efficiency can reduce the amount of energy required to heat your water and may help lower ongoing household energy costs. Heat pump and solar hot water systems are among the most energy-efficient options available, although their suitability depends on the property, installation location and household usage.
Eligible NSW households and small businesses replacing an electric or gas water heater may qualify for an upfront discount through the NSW Government’s Hot Water Upgrade Incentive. Eligible heat pump and solar systems may also receive Australian Government support through Small-scale Technology Certificates (STCs), which are generally applied as a discount on the purchase price.
Incentive amounts and eligibility requirements vary according to the existing system, selected replacement and installer, so we can explain the options available when preparing your quote.
Electric hot water systems
Electric hot water systems remain a practical option for many homes and apartments. They are available in a variety of capacities, including compact models designed for laundries, cupboards and other restricted spaces. We can supply and install a new electric hot water system, replace an existing unit or assess whether another type of water heater would better suit the property.
Gas hot water systems
We supply, replace and install gas storage and instantaneous systems. Gas storage systems heat and store water in an insulated tank, while instantaneous systems heat water as it is required, eliminating the need for a storage cylinder. The most suitable option will depend on the available gas supply, household demand, water pressure and installation location.
Solar hot water systems
We supply, replace and install solar hot water systems that use roof-mounted collectors to absorb heat from the sun. Most systems also incorporate an electric or gas booster to provide reliable hot water when solar energy is limited. Solar installation can involve rooftop work, lifting equipment, plumbing, electrical connections and, in some cases, gas work. Our team has the licensed tradespeople and specialist equipment required to manage the complete installation.

Heat pump hot water systems
We supply, replace and install heat pump water heaters, which transfer heat from the surrounding air into the stored water. Under suitable operating conditions, they can use considerably less electricity than conventional electric storage systems. Before recommending a heat pump, we consider the installation position, ventilation, available space, household demand and potential operating noise.
Lower North Shore customer jobs
Our team repairs, replaces and installs hot water systems throughout the Lower North Shore every week . The following examples demonstrate some of the problems and installation requirements we regularly encounter.

Emergency gas hot water replacement in Mosman
A Mosman customer contacted us after waking to find they had no hot water. Our technician attended the property that morning and inspected the ageing gas storage system.
The old water heater was several decades old and replacement parts were no longer available, making repair impractical. After discussing the household’s hot water requirements, we recommended a 170-litre Everhot outdoor gas storage system that could be installed in the existing location.
We disconnected, drained and removed the old system before installing the new water heater. The installation included the required plumbing and gas connections, testing and commissioning.
Once the work was complete, we cleaned the installation area and removed the old tank for recycling.

Electric-to-gas hot water conversion
A Lower North Shore homeowner decided to replace an ageing electric water heater with a gas storage system while the property was undergoing renovations.
After assessing the household’s hot water usage, available natural gas supply and proposed installation location, we recommended an Aquamax stainless-steel gas storage system.
The old electric unit was disconnected, drained and removed. We then installed the new gas system and completed the necessary gas and plumbing connections before testing and commissioning it.
Because our team includes licensed plumbers, electricians and gas fitters, we were able to coordinate the different aspects of the conversion without requiring the customer to organise several tradespeople.

Compact Rheem system installed in an apartment
A customer contacted us after the electric hot water system in her Mosman apartment suddenly stopped working.
The existing Rheem system was installed inside a laundry cupboard and was more than 20 years old. Due to its age and the limited availability of replacement parts, installing a new system represented better value than attempting a repair.
We drained and removed the old unit before installing a compact Rheem electric storage system in the same location. Working within the restricted cupboard space required careful planning to ensure the replacement system fitted correctly and could be safely connected.
The new unit was tested and commissioned, and the old tank was removed from the property for recycling.

Instantaneous gas hot water repair after an electrical storm
Following a severe Sydney electrical storm, a Lower North Shore customer found that their Rinnai instantaneous gas hot water system had stopped working.
Our technician tested the system and identified components that had been damaged by an electrical surge. Although the water heater was older, it remained in serviceable condition and did not require complete replacement.
The faulty components were replaced before the system was reconnected, recommissioned and tested. This restored the customer’s hot water without the unnecessary expense of replacing the complete unit.
Frequently asked questions
Can my hot water system be repaired?
Many hot water faults can be repaired, particularly when the tank is structurally sound and replacement parts remain available. We will inspect the system and compare the likely repair cost with the cost and benefits of replacement.
What should I do if my hot water system is leaking?
Turn off the water supply to the system if it is safe to do so and contact a hot water specialist promptly. Water leaking from the storage tank itself can indicate internal corrosion and may mean the system requires replacement. Do not touch the system or surrounding water if you suspect an electrical fault.
Can you replace my hot water system on the same day?
Same-day replacement may be possible when a suitable system and technician are available and the installation does not require extensive alterations. The timeframe will depend on the system type, location, access and work required.
Do you repair hot water systems in apartments?
Yes. We repair and replace hot water systems in apartments throughout the Lower North Shore. We can assess restricted installation spaces, building access and the existing plumbing and electrical connections before recommending a replacement.
Can you replace an electric system with gas?
This may be possible if the property has a suitable natural gas or LPG supply and an appropriate external installation location. The conversion may require plumbing, electrical and gas work, which our licensed team can coordinate.
Can I switch from gas to a heat pump?
Yes, subject to the property’s electrical supply, available space, ventilation and other installation requirements. We can compare the practical requirements and costs with those of replacing the existing gas system.
Do you remove the old hot water system?
Yes. When included as part of the installation, we can remove the old water heater and associated installation waste from the property for appropriate disposal or recycling.
What size hot water system do I need?
The correct size depends on the number of people in the household, the number of bathrooms, typical showering habits, appliance use and the type of system selected. We will consider your actual hot water requirements before recommending a capacity.
How long does a hot water system last?
The service life of a hot water system varies according to the system type, water quality, installation, usage and maintenance. If your system is ageing or requiring repeated repairs, we can assess its condition and help you plan a replacement before it fails completely.
