Sydney water boiler

Last updated on May 21, 2022

It may be hard to remember in the beautiful Australian summer, but you’ll need more than a pot of tea to stay warm in the cold months of June, July, and August.

Although many business facilities still rely on plug-in heaters and radiators, they are not just energy hogs, but may also be dangerous – especially if they’re old or not utilized regularly. 

Due to their high-power usage, reverse flow air conditioners can also be potentially troublesome.

As a result, an increasing number of businesses are switching to water boilers, which provide safe central heating at a fraction of the cost of alternative options

Water boilers are recognizable to those who have lived abroad due to their extensive usage in both companies and homes, but they have only lately gained traction in Australia.

Don’t worry, Australian Hot Water is here to walk you through available water boilers, the differences between them, and which option is ideal for your company.

What is the essence of a water boiler?

A water heater is a form of integrated or robotic heating system that uses pipes to deliver boiled water around a building. These are centrally planned, as the name implies, which means you can use the same device to heat your entire business.

What are the various types?

There are several types to choose from, and they come in a range of sizes. You’ll generally have to go electric if your building isn’t gas-connected; however, there are oil and LPG options as well.

Electric boilers are often less expensive to operate, quieter, and more efficient. However, gas boilers are more ecologically friendly — unless your power supply is primarily renewable.

Each unit’s maintenance expenses are comparable and will be determined mostly by the size of your building or buildings, as well as any additional requirements you may have.

As always, Australian Hot Water has professionals on hand, so you’ll never be left waiting for technical assistance – or just a little more information.

Conventional Water Heaters vs. Electric Water Heaters

Isn’t it true that if you need a heater, you should acquire a gas boiler? Wait! Are you certain that’s your best option?

They’re expensive, huge, and unreliable. Replacing an old boiler with a new one is one of the most expensive home improvements, not to mention a major inconvenience…

The disadvantages of traditional water heaters sometimes outweigh the benefits, which is why an increasing number of people are opting for electric boilers.

A high-quality gas model may cost up to £5000 – including installation and removal – even though the product is rarely used enough to be cost-effective. 

Electric ones, on the other hand, are less expensive and provide effective, environmentally friendly heating with no drawbacks when used properly.

So, how do the electrical and traditional approaches stack up?

Comparison of efficacy

Electric water heaters today are extremely energy efficient. They use all the consumed energy to heat the boiler. 

This efficiency is significantly higher than that of gas boilers, which are about 80-90 percent efficient at most, a figure that can drop with time. 

Gas boilers lose some heat through the roof or ventilation system, but electric heaters do a great job of maintaining the specified temperature.

Traditional boilers consume energy to keep the water heated at all times; they are good at reheating water when the tank is full, but this is offset by their poor heat retention. 

Electrically driven stored water heaters utilize coiled elements to heat water and function intermittently to keep the temperature at a pre-set level, reducing energy waste.

Many households are opting for tankless electric water heaters that heat water on demand, and which are slightly more expensive. 

If the water source is not utilized frequently, this can save a lot of money in the long run. 

Electric water heaters are both efficient and cost-effective, making them suitable for small families, landlords, and commercial buildings.

Comparison of controls

Electric water heaters provide unrivalled control over your heating. If you’re replacing a ten-year-old boiler for the first time, you should be aware that contemporary heating solutions have evolved, becoming far more complex and controllable.

Lot 20 authorized electrical heating systems with superior energy-saving technology and adjustable settings are now available. New models have built-in WIFI allowing smartphone control and usage indications.

An electric thermostat or control panel can be linked to a normal gas boiler, but these accessories must be factored as additional expenditures, and often they can only switch the boiler on and off at certain times.

Modern electrical options, on the other hand, give you full control of your heating by allowing you to establish precise temperature settings and programs, boosting comfort and safety. 

You’ll never be caught off guard again, as you can contact your boiler remotely and switch between bespoke 24/7 timers or trigger a boost option for extra warmth when you need it. 

Expense comparison

The initial expenditures of gas and other traditional boilers are immediately noticeable, and they significantly outweigh the cost of an electric water heater. 

Traditional boilers are advertised as having lower overall costs than electric boilers; however, this is only true in certain situations and only if you stay put long enough to get the most out of the new boiler.

However, if you expect to stay in your home for longer than the heater’s lifespan and choose an old-fashioned gas type, you’ll forego the efficiency and technology that newer electrical versions provide.

Long-term operating expenses may be decreased by using your electric water heater sensibly – customizing personal settings and remotely monitoring energy loss – which may ultimately prove to be significantly cheaper compared to the potential savings offered by a traditional boiler.

What do you anticipate the lifespan of your water heater will be?

It would be great to know when your water heater needs to be replaced before it explodes and causes a mess or, worse, property damage. 

The average lifespan of a residential water heater is 6 to 13 years. After 12 years, you’re on borrowed time! 

The type of water in your tank, as well as whether you’ve followed the manufacturer’s suggestions for draining and cleaning it once a year, may have an impact on its lifespan. In reality, this is a rather uncommon event among homeowners.

What Are Some Signs That My Water Heater Needs to Be Replaced?

If you see any of these warning signs, you’ll have more time to think about your options for type, size, and model rather than scurrying late on a Friday night to find a replacement after your heater’s spilled all over your house.

What Is the Cost of Replacing a Hot Water System? What Factors Influence the Cost of Your Project?

In Australia, the typical cost of building a new hot water system ranges between $200 and $600.

In essence, the price of a hot water installation might vary greatly.

➡ What Size Water Heater Do You Need in Your Home?

First, you need to determine the magnitude of the water boiler you need in your house. Water heaters with a larger tank capacity or heating capacity will cost more than smaller units. 

This is applicable if you are using an electric water tank, such as a heat engine, a photovoltaic boiler, or a natural gas boiler.

Choosing the correct size will help you save money on the installation and operation of your water heater.

➡ The Brand, Model, and Type of Water Heater You Select

Water heaters come in a variety of types;

  • Gas water heaters – In gas heating installations, pure gas is utilized to heat the water. These heaters are available in tank-based and on-demand configurations. Tank-based water heaters are often less expensive upfront, but they are less efficient than on-demand ones on the long term.
  • Electric heaters – Electric water heaters employ electric heating components and are available in bunker and tankless, instantaneous models. As a result, we strongly advise speaking with an experienced plumber about how much hot water your home requires. Tanks range in size from 25L to 400L, and tankless, on-demand heaters vary substantially in their capacity as well. They are usually approximately the same cost as their gas counterparts, yet due to the low cost of natural gas, they cost a little more to operate.
  • Heat pump water heaters – Despite their high cost, heat pump water heaters are extremely efficient. They work similarly to a reverse refrigerator in that they take heat from the air and use it to heat water.
  • Solar water heaters – These heaters capture the sun’s heat and utilize it to warm your water. They require little to no electricity to operate, but because they are typically installed on your roof, they can be costly to install.

All of these systems have varying pricing — and different manufacturers charge different prices for similar products. 

You’ll need to conduct some research to determine which type, brand, and model of water heater are best for you.

➡ Changing the Type of Water Heater in Your Home

You’ll save money on installation if you replace an electric tank-based water heater with a similar model. Plumbers will be able to swiftly remove the old unit, replace it, and connect it to your plumbing system.

However, if you make a larger shift, such as switching from an electric tank-based heater to a gas-powered, on-demand tankless heater, you will spend more.

You’ll need to hire gas fitters and plumbers to install new pipes, and your pipework might need to be modified as well. If you decide to switch to a different type of unit, be ready to spend more.

➡ Costs of Delivery for Your Water Heater

Some water tanks are heavy and unmanageable, weighing up to 150 kilos and requiring delivery workers and specialized equipment. 

Make sure to include this cost in the overall cost of replacing your hot water heater.

Furthermore, if there are any impediments to installing the water heater, such as narrow and steep steps that would make delivery more difficult or require special equipment, you may be charged a higher delivery and installation fee.

➡ Costs of Installation

To install your hot water heater, you’ll need to employ a professional plumber. 

The price of setting up a new hot water system varies significantly based on the model of boiler you select, whether or not you want pipeline or electrical scheme adjustments, and many more criteria. 

Tempering valves, for example, are needed in all water heaters that utilise storage tanks under an Australian law passed in 2012. 

This valve is an anti-scald device that maintains your water temperature below 60° C, and installing one can cost you up to $200, so it’s worth keeping in mind. 

Your plumber will assist you in understanding any additional fees and criteria that must be met while installing your new unit. 

The cost of a hot water tank installation is also affected by the time it takes to install the unit. 

A basic setup usually takes 1-2 hours; however, a highly comprehensive configuration may take four hours or more. 

Because most plumbers charge by the hour, this will result in greater installation charges.

Getting Rid of an Old Water Heater

Most plumbers will not remove your old water heater for free, and you might need to pay them to have it removed. 

This isn’t usually a huge expense, but it’s something to keep in mind when calculating the entire cost of replacing your hot water system.

What is the cheapest method to warm up your home’s water?

Would an electric detachable boiler or a gas tankless water heater be less expensive to run?

The cost of electricity in your area will determine this. Natural gas, followed by electricity and propane, is frequently the most cost-effective means to heat water. 

To find out, use the hot water energy cost calculator in our article on Choosing a Hot Water Heater to compare the fuel prices in your location by entering the amounts you pay for electricity and propane on your utility bill.

Although the calculator is intended for tank-style water heaters, and tankless ones are 20% to 30% more fuel-efficient, it should still provide you with a comparison of which type of fuel is the most cost-effective for heating water in your location.

Electric tankless water heaters are available, but they’re generally tiny “point of use” machines that only give hot water to a single basin or shower. 

Because it would need a very big electrical line and breaker to deliver adequate energy for many hot water users, most tankless water heaters used to heat water for an entire home, run on gas.

Also, bear in mind that gas tankless water heaters require a bigger gas line, therefore the gas line you now have going to your tank-type water heater will almost certainly need to be replaced.
