Instant, Gas & Electric Systems

Gas & Electric Hot Water Systems Perth

Around 27% of the average WA household’s energy consumption goes to heating water. The more people you have in your home, the more hot water you use.

Reducing the amount of energy required to heat water or finding alternative ways to heat water can significantly reduce your power bill. A new hot water system for your Perth home can give you hot water where and when you need it.

Choosing the right system can help you maximise your long term savings. REnew Energy offers free consultations and assessments to help you find the water heating system that best suits your needs.

Hot Water Systems Perth

Traditional hot water systems in Perth come in two categories: gas and electric. Around 67% of Perth residents use gas for water heating. In WA overall, about 62% of homeowners use gas, with the remainder of households split almost evenly between solar and electric hot water systems.

Hot water systems work in two different ways. Instant or continuous flow systems heat water on demand. Storage hot water systems heat a large amount of water in a tank and keep it at a consistent temperature until you need it.

Whether you want an instant, gas or electric hot water system, Renew Energy has a system to suit your hot water needs. Using only the most trusted brands on the market, we supply and install the very best systems using quality workmanship. Offering the standard manufacturer’s warranty on the system, plus a 5-year warranty on all labour we perform, Renew Energy has got a solution for your home that is guaranteed.

Our extensive range and vast experience choosing and installing hot water systems ensures we can tailor a solution that is just right for you or your business. We only use trusted brands and accredited installers to ensure you get a long-lasting hot water system – after all, a smooth-running system is good for both you and us!

Gas Hot Water Systems

Most people use gas to heat their water in Australia. You can choose from an instant- or storage-based gas hot water system.

Instant Gas Hot Water Systems

Instant gas hot water systems are more energy-efficient than storage-based ones. They feature a small, tankless design that you can tuck away in a closet or behind a low wall, and they don’t lose nearly as much heat as a big tank. 

The water runs into the heater from one side, where the system heats it instantly as it passes through the unit. It then delivers hot water on demand for as long as you need it.

Gas only turns on when you’re using the water heater. Unless you have a faucet running and demanding hot water, the unit remains in stasis. Once you turn on a hot tap, the gas kicks on, and the unit heats the water. 

If you use a lot of water in your home, you might want to consider an instant gas water heater. You can use an unlimited amount of hot water without ever running out. Since the gas fonly kicks on intermittently, you can save on your gas bill.

Storage Gas Hot Water Systems

A gas storage hot water system has a large water storage tank positioned over a dedicated gas burner. The continuous pilot flame triggers the main burner when the water in the tank drops below the preset temperature. Hot water exits the tank from the top, and cold water enters the tank at the bottom. 

Most units have a thermostat you can adjust to control the temperature of the tank water. If you don’t use much water, you can keep the heat of the tank lower. If you use more hot water, you can crank up the temperature and mix with cold at the tap.  

Your gas hot water storage tank will typically store between 135L and 170L, although smaller and larger containers are available. If you have a large house, you may wish to have two hot water tanks to allow heated water to reach taps on opposite ends of the home more quickly.

Electric Hot Water Systems

Electric Hot Water Systems

If you are concerned about a gas line in your home for any reason, you may decide on an electric hot water system. Like gas systems, electric hot water systems come in instant and storage versions.

Instant Electric Hot Water Systems

Like its gas counterpart, an instant electric hot water system has a small tankless unit. It sits in an out-of-the-way spot, plugs neatly into the wall, and heats water on demand. 

You may find it easier to install an electric on-demand water heater if you’re doing a remodel and don’t want the hassle of running a gas line to a new point.

Storage Electric Hot Water Systems

If a gas or solar-powered water heater won’t work in your space, you can use a tanked water heater with electric power. This system has no pilot light. Instead, the programmable thermostat senses when water drops below your preset temperature and kicks the electric heater on to reheat it. 

As with a gas water heater tank, cold water flows in at the bottom of the unit, and hot water flows out from the top. 

Gas vs. Electric Hot Water Systems

Comparing gas and electric hot water systems reveals specific pros and cons for each option. The one that works best for you depends on your home’s space and hot water needs.

Gas Pros

  • Gas is typically cheaper and more efficient than electric.
  • Many older homes are designed for gas heat systems.

Gas Cons

  • Gas has an inherent risk compared to electric.
  • Gas systems won’t fit in tight spaces.

Electric Pros

  • Electric is safer than gas and cheaper to install in a new build or remodel.
  • Systems can fit in a smaller area.
  • Electric systems typically last longer since they experience less corrosion.

Electric Cons

  • Electricity prices can be much higher than the cost of gas.
  • Electric systems produce the most greenhouse gas emissions.
  • Using electricity to heat water is less efficient than using gas.

FAQ

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

If you need to replace a hot water system, your costs will depend on several factors, including:

  • The type of system you are replacing, whether it’s electric, gas, or solar
  • What kind of replacement system you have chosen to install
  • Whether or not your current setup meets Australian Standards
  • Where you’re installing your system and if any renovation is needed  

If you replace an old, inefficient hot water system with a new, energy-efficient one, your savings over time can offset the cost of replacement. If you opt for a solar hot water system, you can recoup the added expense over the system’s lifetime and enjoy even more savings.

What is the most efficient kind of hot water system in Perth?

If you’re shopping for hot water systems in Perth, consider solar hot water. It’s the most efficient option, as you can heat water year-round using the sun’s power. In winter or on overcast or rainy days, you can use a gas or electric booster to help raise your water temperature to acceptable levels.

What is the cheapest hot water system?

You don’t want the cheapest hot water system for your Perth home. A cheap system means buying one manufactured with lower-quality materials and a warranty that may not be worth anything. 

Instead, look at mid- to high-price hot water systems, so you can rest assured yours will last and that you can obtain service and parts if needed.

We only sell brands from manufacturers who have experience and a good reputation in the industry. Every water heater we sell, whether gas or electric, is backed by a strong warranty. We also demand systems be highly energy-efficient to save you money long-term.
