Water Heater Installation mandurah - mandurah plumber

There are two main types of hot water system: continuous and storage.

Storage systems heat up water and then store it in an insulated tank for when you need it while continuous (or tankless) systems only heat water when it’s requested.

Continuous systems tend to be powered by gas, but you can get electric models too. Solar and electric systems commonly use a tank.

Hot water is a luxury many of us take for granted in Australia. From hot showers to washing your dishes, hot water is a comfort that we all want in our homes, but if your system ever breaks down you’ll soon understand its importance.

To fix it, you’ll need to understand how does a hot water system work?

Basics of how a hot water system works

There are two main types of hot water system: continuous and storage. These are then broken down into different power sources.

Storage systems heat up water and then store it in an insulated tank for when you need it while continuous (or tankless) systems only heat water when it’s requested.

Continuous systems tend to be powered by gas, but you can get electric models too. Solar and electric systems commonly use a tank.

How does an electric hot water system work?

With a tank system, you’ll find a heating element at the bottom of the unit to keep the water warm, making it instantly available.

In a continuous system, there will be an electric heating element coiled wrapped around the pipes to heat the water as it travels to the taps.

While electric systems are reliable, they also tend to be the most expensive heating option.

How does a solar hot water system work?

Solar hot water systems harness energy from the sun using panels on your roof. This converts the energy into heat to warm water in a tank.

Although solar hot water systems have a high upfront cost, they are the cheapest to run and the best from an environmental standpoint.

Most models have a gas or electric back up for times when the weather isn’t suitable for heating water.

How does a gas hot water system work?

Some hot water tanks have a gas burner that’s on continuously to keep the water warm. Continuous systems make use of a gas burner only when hot taps are turned on.

These work well if you have mains gas installed, but bottled gas versions tend to be more expensive.

How does a twin element hot water system work?

Twin element hot water systems are more common than single element systems nowadays.

With single element heaters, there’s one heating element at the bottom of the tank. This is generally set to work overnight when power is at an off-peak rate, saving you money.

With a twin element (or dual element) heater, you have two heaters in the tank: one at the top and one at the bottom. These work together to give the water a more even temperature.

By having two elements, the water heating system is more efficient (although it may cost slightly more to install).

How does a cylinder hot water system work?

A cylinder hot water system is simply another name for a tank. It is more commonly used in the UK than in Australia, but they are designed and function in the same way.

What size hot water system do I need?

Before you buy a new system, you need to answer the question of what size hot water system do I need?

If you buy a storage heater that’s too small, it will keep running out of hot water and you may risk having to have regular cold showers. However, get one that’s too big and you’ll be wasting money keeping it unnecessarily warm.

Australian government figures state that around 20% of a home’s energy is used to heat water, so buying an energy-efficient model is good for your pocket and the environment.

One of the biggest deciding factors is how many people will be using the water. For an electric tank heater, around 180 litres is a good size for one to three people. However, that won’t nearly cover a family of five, who may need a tank up to 450 litres in size.

How to install a hot water system in your home

Installing a hot water system is not a DIY job because it includes plumbing work and often electrical or gas work as well.

If your hot water system has stopped working, you may be able to buy a new part rather than a whole new system.

How long do hot water systems last? As a general rule, you should expect to get at least 10 years from a hot water system, but this can change depending on usage and other factors.
