Picking out the right hot water system for your home is dependent on a few things such as your household size, estimated water usage, and what services you have available such as your current connections and electrical rates, gas supply and places to install solar panels. With over 20 years of experience our team is happy to help you decide on the best system for your home. We can give you free advice over the phone, you can email though your electricity bill for us to analyse and we can come to your home to give a free quote and advice on various replacement options.
Traditionally, hot water systems are considered old after the age of ten years and commonly would last around 10-15 years. However, with 5 yearly servicing including replacing your sacrificial anode and pressure relief valve, storage gas and electric hot water systems have a life expectancy of 20 years and more.
Exclusive to Hogan Hot Water & Air, our Aquamax 125 litre, 250 litre, 315 litre and 400 litre models now come standard with 15 years cylinder warranty – made by Rheem Australia Pty Ltd, these systems are built to last!

For residential water heaters, the size can be determined based on your family size and what type of heater you’re getting. These numbers are estimates, however, and we encourage you to contact us to help figure out the perfect system for your home and budget.
- 1-3 people with regular water usage should look at 250 litre electric tanks or 135 litre gas tanks.
- For larger households you need at least 315 litres for electric and 160 litres for gas.
Our electric systems are off-peak, heating water up overnight when electrical rates are low. Householders then have the tank’s capacity to draw off throughout the day and evening as required.
- Environmentally friendly and very economical to run.
- Can take a while to reheat once the available hot water is used up.
Storage systems heat the entire storage tank providing instant hot water to the home.
- No initial wait time for hot water.
- Energy costs can be higher based on your household’s usage as the system maintains the water temperature 24/7.
- Once the capacity is used the tank must heat up again before it can provide hot water.
Continuous flow systems heat the water when and as you need it.
- No need to wait for the tank to reheat
- Lower energy cost
- Compact, can be mounted on a wall
- Can take a second or two for the unit to get up to temperature to provide hot water
Using collector panels installed on your roof, solar systems use a dark surface to trap and transfer the sun’s heat to the water running through it. The hot water is stored for use any time.
- Solar hot water systems can be combined with solar power and battery storage.
- Government incentives are sometimes available, contact us for more information.
- If the water temperature drops below a certain level an electric or gas system will kick in to reheat the water.
- Relatively expensive initial set up.
Like split system air conditioners, a heat pump water heater runs off electricity and absorbs warmth from the air to heat the water. Heat pump systems are available as integrated/ compact systems where the storage tank and compressor are one unit, or split system where the tank and compressor are separate.
- Roughly three times more efficient than traditional water heaters
- Save energy and money, and reduce greenhouse gas emissions when used in the right environment
- Work well in warm climates drawing from the available warm air
- Don’t work as well in colder climates or in the colder winter months
Gas systems running costs vary based on whether you’re connected to the mains with natural gas, or LPG and what type of system you’re running, storage or instant. The annual running costs average between $295 up to $665.
Electric systems running during peak hours average between $790 and $925 per year. Off-peak storage systems cost on average $700 annually.
Solar systems start as low as $65 annually for a natural gas boosted up to $365 for an electric boosted peak tariff standard system.
Heat pumps annual running costs start at $160 and go up to $385 annually.
According to CanStar Blue’s recent survey, Electric water heaters are the most popular, followed closely by Gas. Solar and Heat Pump systems were shown to be the least popular in the past five years.
In the ideal situation your home would be connected to mains gas and receive moderate amounts of sunlight making a solar storage with gas booster system the best for your energy costs and the environment.
The best though depends on what you’re able to afford, home location, and available utilities. Contact us today to schedule an onsite inspection and estimate.
Consider installing an off-peak hot water system installed; they automatically heat the water during the hours of 11pm to 7am and store for later use. You can also use your hot water during off peak electricity hours, contact your provider to find out more.
If available, consider a controlled load tariff or dedicated circuit where your system is metered separately and charged at a lower rate. Also, if you haven’t already, switch to using cold water in your washing machines or purchase one that heats the water up itself.
