Types of Hot Water Systems We Install
Electric Hot Water Systems
Electric hot water systems are reliable, cost-effective, and easy to install, making them popular for many households. They use an internal heating element to warm water stored in an insulated tank, ensuring a steady hot water supply when needed.
Benefits:
- Suitable for homes without gas connections
- Available in a wide range of sizes to suit different household needs
- Can operate on off-peak electricity to reduce energy costs
Cons:
- Generally slower to heat water compared to gas systems
- Higher running costs compared to gas and instantaneous systems

Gas Hot Water Systems
A gas hot water system is an efficient, environmentally friendly option that provides instant and reliable hot water. These systems heat water using a gas burner, making them faster and more cost-effective than electric models.
Benefits:
- Heats water more quickly than electric systems
- Lower running costs, especially if connected to natural gas
- Works efficiently even in high-demand households
Cons:
- Requires access to a gas connection
- Higher initial installation cost compared to electric systems

Instantaneous Hot Water Systems
Also known as tankless or continuous flow systems, these units heat water only when needed, reducing energy waste and ensuring a constant supply of hot water without the need for a storage tank.
Benefits:
- Provides unlimited hot water on demand
- It is more energy-efficient as it doesn’t require heating a whole tank
- Compact size, freeing up space in your home
Cons:
- May struggle to provide hot water simultaneously to multiple taps
- Requires proper gas or electricity supply to function efficiently

Under-Sink Hot Water Systems
Under-sink hot water systems like Zip or Rheem models provide instant boiling or warm water at the kitchen sink. They are commonly used in offices, small households, and commercial spaces where immediate hot water is required for tea, coffee, or cooking.
Benefits:
- Provides near-instant hot water for kitchen use
- It saves energy compared to constantly heating a large tank
- Compact and easy to install under kitchen sinks
Cons:
- Limited capacity, making them unsuitable for full household use
- It can be costly to run if used frequently

Common Hot Water System Issues (and How We Fix Them)

“My current hot water system isn’t big enough for my household.”
An undersized system can lead to cold showers and frustrating water shortages, particularly during peak usage. Our team will assess your household’s water usage and recommend a suitably sized system to ensure your family always has a consistent and reliable hot water supply. We offer solutions such as installing a larger storage tank, upgrading to an instantaneous system, or adding a booster to meet higher demand.
“My energy bills have increased, and I think my hot water system is why.”
Older systems lose efficiency over time, using more energy to heat water due to sediment buildup, aging heating elements, or insulation degradation. Our specialists will conduct a detailed energy efficiency assessment to determine whether repairs or a system replacement would be more cost-effective. We can also install energy-efficient alternatives, significantly reducing ongoing electricity or gas costs.
“The last plumber installed my hot water system, but it wasn’t done correctly.”
Improper installations can lead to inconsistent water temperatures, leaks, and early system failures. We begin by conducting a thorough inspection to diagnose any installation issues. Our licensed plumbers will correct any errors, replace faulty components, and ensure compliance with Australian plumbing standards, giving you peace of mind that your system will function efficiently and safely for years.
“I want to switch from an electric to a gas hot water system.”
Transitioning from an electric to a gas hot water system can reduce energy costs and improve heating efficiency, but it requires professional installation and compliance checks. We manage the entire process, including gas line installation, appliance connection, and system testing, ensuring your new system is installed to the highest safety and efficiency standards.
“My hot water system is leaking, but I’m unsure if I need a repair or a replacement.”
Leaks may indicate a failing tank, faulty connections, or pressure issues. We begin with a system diagnostic, checking for visible and hidden leaks to determine the cause and severity of the problem. Minor leaks, such as a faulty valve or pipe connection, can often be repaired quickly and cost-effectively. However, if the tank is corroded or structurally compromised, we recommend replacing it with a durable, energy-efficient model with long-term reliability.
“My hot water drops off when someone else uses another shower, dishwasher, or washing machine.”
If your hot water fluctuates or runs out quickly when multiple taps or appliances are used, it could be due to an undersized hot water system or limited water flow capacity. We assess your home’s hot water demand and recommend upgrading to a more extensive storage system, installing a continuous flow unit, or improving your water pressure with a booster pump. This ensures consistent hot water throughout your household, even during peak usage.
After dealing with a stubborn blocked drain for weeks, I finally called in the experts. They quickly identified the issue and had it fixed in no time. Excellent service!
