I had a problem with my water heater on Saturday and Anytime Hot Water Sydney was able to send someone out on Sunday, I had called Saturday evening so this was an urgent appointment. Russell came out the next day to start work on our water heater. He was very professional and did a great job getting it back into service within an hour.

Frequently Asked Questions

When your hot water system breaks down, either by a simple shut down or a more dramatic burst water tank and flooding, it normally happens very suddenly.

And once this happens, most people don’t take the time to look into all of their options as they take cold showers; instead, most people will simply replace the hot water unit with something identical or equivalent right away.

This tends to mean that many people miss out on the opportunity to find a better product.

The old one worked fine, so let’s just get the same thing to avoid trouble

Because hot water takes up so a large part of your household power consumption (generally around one quarter of it), it is well worth reviewing how much power your system uses and comparing it to some alternatives before your system breaks down, while you still have the leisure.

You may find before long that many other HWSs (hot water systems) can save on energy and money while being friendlier to the environment.

Another thing to consider is any new regulations aimed at lowering household energy use in your state, as a new electrical system may not even be an option for your household.

Electric hot water systems may seem to be the most inexpensive option because they are relatively cheap to purchase as well as install.

However, over time these systems will actually cost you more in energy costs, especially if you are using a continuous or full day rate.

If your system runs on off-peak electricity it can be much kinder to your energy costs, but will also make it necessary to have a larger tank so that the water heated overnight will last throughout the day.

Please investigate your particular energy situation as off-peak electricity is not available for every home.

For an average four-person home, you will generally need a 125-160 litre tank if you have a continuous system, or a 250-315 litre tank if you are using off-peak electricity.

Electrical hot water units can be installed either inside or outside of the home.

Instantaneous electric water heaters are available as well.

And finally an electric hot water storage tank will typically cost between $500-$1500 to buy plus installation.

Natural gas can be a great option if your home has access to it. Generally the rate is much cheaper than electricity (but unfortunately gas prices are rising).

Another advantage is that gas rates do not fluctuate throughout the day, and can simply heat water as needed.

For a four-person home you should have a tank of around 135-170 litres.

Instant Electric Hot Water System are also available for natural gas. These systems tend to be installed outdoors on account of the venting requirements, though it is possible to install them inside if you have a flue.

These systems have an excellent energy efficiency rating. Some of them use a pilot light which uses a very small amount of gas, and others use electric ignition which is more economical.

The advantage of the pilot light however is that you can keep your hot water during power outages.

One alternative to natural gas is LPG or liquid petroleum gas, but the running costs will be significantly higher. Not including installation, a natural gas system will cost around $900-$2000.

These systems have solar collector panels and a storage tank. For a 4 person home, you will generally need two solar panels, or four square metres, along with a 300-360 litres tank.

The larger tank is needed to make up for days of minimal sunlight. Also note that four square metres of panel is recommended for an ideal collection position.

If your home doesn’t allow for your panels to be set up in an ideal place where they get a lot of direct sunlight, you may need to invest in more panels.

Some solar hot water systems also have an electric or gas booster element in the storage tank as a backup, to keep you going through periods without much sunshine.

Unlike electric hot water systems, solar hot water systems are typically the most expensive to buy as well as install.

But also unlike electrical hot water heaters, a well-functioning solar hot water heater will be very inexpensive in the long run as the running costs can be extremely low.

You may also be able to take advantage of government rebates or other incentives to help out with the purchase cost.

Solar systems, not including installation, will generally cost around $2000-$7000.

This is an efficient kind of hot water storage in that it works according to roughly the same principle as a fridge or air conditioner: it heats the water in your tank by extracting heat from the air.

Normally these systems have the tank and compressor integrated together, but a split system with the tank and compressor separated are also available.

These water heater systems need to be installed in a well-ventilated place, so outdoor installation is ideal.

Be aware that like air conditioners, the outdoor units of these systems can be quite noisy, so it is better not to install them too close to a neighbouring home.

These systems are ideal for warmer climates, though they can be made to work in a colder climate by including a booster element to keep your water warm on colder days.

For a four-person home, you will generally need a tank of 270-315 litres. You can also find government rebates or incentives to help offset the relatively high cost of purchasing and installing one of these systems.

The price for these systems will range from $2500 to $4000 (minus the installation).

Generally speaking a household will use about 50 litres of hot water per day. If you wash clothes in hot or warm water, take long showers, or use a dishwasher then the average amount per person could be considerably higher.

It is recommended to get your supplier to analyse your household and its water needs and then recommend some appropriate options for you. Your supplier should be asking you questions about how much water you use as well as when you use it.

Does everyone in the house shower in the morning or in the evening? Do you wash your clothes in hot or warm water? It is best when possible to get quotes from more than one supplier.

For most homes, solar heating systems are generally the most efficient and cheapest to run, but this option can be impractical for some homes for a variety of reasons, and your supplier will be able to recommend a number of different efficient and cost-effective options if solar heating isn’t ideal for your particular situation.

Gas water heating systems generally have the best energy star ratings for efficiency (the more stars it has the better, with the highest rating being six starts).

This is a good way to quickly assess the energy efficiency of heating systems, but keep in mind that this rating scheme is not regulated by the government.

Having hot water heater / system problems? If so follow the quick guide below before you call a hot water plumber for a hot water system repair or replacement.

This quick guide might just save you both headaches and money.

The guide will also give you an idea/understanding of the hot water system problem at hand.

Note this guide is electric water system specific.


You will need to know how to use a multimeter and follow all safety rules when working with electricity. Never open hot water system access panels whilst the power on. Always check the water unit’s power to be sure its off. Don’t trust a circuit breaker label.

Use a multimeter to check an outlet that you know is working before checking inside the water heater.
