These compact, wall-mounted units are designed to meet your household’s peak hot water usage, ensuring a reliable supply without the need for a bulky storage tank.

The choice of a tankless water heater depends on several factors, including the size of your household and the type of fuel available. Gas-powered models typically offer higher flow rates, making them ideal for larger families, while electric models are easier to install and maintain.

Understanding your specific needs and the capabilities of different tankless systems allows you to select a hot water solution that delivers both comfort and efficiency.

Introduction

In the average Australian household, heating water accounts for about 30% of the energy budget, making it a significant expense. Australian Hot Water offers a range of services, including the supply, installation, and maintenance of hot water systems, ensuring that your home has a reliable and efficient hot water supply.

Choosing the right system not only saves money but also reduces your environmental impact.

Understanding On-Demand Water Heaters

Tankless water heaters are often referred to as instantaneous water heaters. They offer hot water as needed, eliminating the requirement for a storage tank. When a hot water faucet is turned on, cold water flows through a heat exchanger, where it is heated instantly. This process ensures that you have hot water whenever you need it, without the standby energy losses associated with traditional water heaters.

The benefits of tankless water heaters extend beyond just hot water on demand. They offer significant environmental advantages due to their energy efficiency and reduced operational costs. Eliminating the need for a constantly heated tank, these systems lower utility bills and decrease your carbon footprint, making them an eco-friendly choice for modern homes.

Types of On-Demand Water Heaters

There are two main types of on-demand water heaters: electric and gas. Both types have their unique advantages and are suitable for different household needs.

Electric tankless water heaters are known for their ease of installation and precise temperature control, while gas models typically offer higher flow rates, making them ideal for larger households.

Electric On-Demand Water Heaters

Electric tankless water heaters use heating elements activated by water flow to deliver hot water on demand. These models are compact, energy-efficient, and offer precise temperature control, making them an excellent choice for homes with adequate electrical infrastructure. However, they can consume between 20 and 60 kW of power per hour, which may necessitate upgrades to your home’s electrical system.

Despite their high operating costs, electric tankless water heaters are an attractive option for those looking to reduce energy consumption and enjoy endless hot water. Their ease of installation and maintenance, coupled with their compact design, make them a popular choice in regions where electricity is more cost-effective than gas.

Gas On-Demand Water Heaters

Gas tankless water heaters are known for their ability to produce higher flow rates compared to electric models, making them ideal for households with high hot water demands. These units can be installed either indoors or outdoors, providing flexibility based on your space and configuration. Powered by natural gas, these heaters require proper ventilation to ensure safety and efficiency, preventing gas leaks and corrosion.

One of the main advantages of gas tankless water heaters is their efficiency in delivering hot water almost instantaneously. However, the need for larger gas lines and proper ventilation systems can increase the complexity and cost of installation. Despite these challenges, the higher performance and potential energy savings make gas models a compelling option for larger homes or those with multiple hot water outlets.

Key Benefits of On-Demand Water Heaters

On-demand water heaters offer several key benefits, including energy efficiency, space-saving design, and an endless supply of hot water. These advantages make them an attractive alternative to traditional water heaters, especially for households looking to reduce energy consumption and enjoy reliable hot water on demand.

Understanding these benefits helps you appreciate why a tankless water heater might be the right choice for your home.

Energy Efficiency

One of the standout benefits of tankless water heaters is their energy efficiency. Unlike traditional water heaters that keep a tank full of hot water, tankless units heat water only when needed, avoiding standby heat losses and significantly reducing energy consumption. Homes using less than 41 gallons of hot water daily can find tankless models 24%–34% more energy efficient than conventional systems, leading to substantial savings on utility bills.

The environmental benefits of tankless water heaters are also noteworthy. By reducing overall energy consumption, these units help lower greenhouse gas emissions, contributing to a smaller carbon footprint. Whether you opt for an electric or gas model, investing in a tankless system can lead to significant cost savings and a more eco-friendly lifestyle.

Space-Saving Design

The compact design of tankless water heaters is another significant advantage. These units are typically wall-mounted, freeing up valuable floor space in your home. Their small footprint makes them ideal for indoor installations, ensuring easy access for maintenance while optimizing space efficiency.

This space-saving design is particularly beneficial for homes with limited storage areas, allowing you to make better use of your living space.

Endless Hot Water Supply

One of the most compelling features of tankless water heaters is their ability to provide an endless supply of hot water. Unlike traditional systems that rely on a storage tank, tankless units heat water instantly as it flows through the system, ensuring a constant supply whenever you need it. This means no more waiting for the tank to refill and reheat, making it perfect for large families or households with high hot water demands.

Whether you’re taking a long shower or running multiple appliances simultaneously, a tankless water heater ensures that you won’t run out of continuous flow hot water. This continuous flow of hot water enhances comfort and convenience, making daily tasks more efficient and enjoyable.

Choosing the right continuous flow systems for your needs allows you to enjoy the benefits of endless hot water without the limitations of a traditional storage tank.

Installation Considerations for On-Demand Water Heaters

Installing a tankless water heater requires careful planning and consideration, including tankless water heater installation. Factors like electrical requirements, ventilation needs for gas models, and the choice between professional installation and DIY play crucial roles in ensuring the safe and efficient operation of your new system.

Understanding these considerations helps you make informed decisions and avoid potential pitfalls during the installation process.

Electrical Requirements

Electric tankless water heaters typically require a 240-volt supply to operate effectively. Even gas-powered models need a 120-volt electric power source for their control systems. Ensuring that your home’s electrical infrastructure can support these requirements is essential for the safe and efficient operation of your tankless water heater.

Ventilation Needs for Gas Models

Proper ventilation is critical for gas tankless water heaters to prevent gas leaks and ensure efficient operation. These units must be vented with Category III stainless steel materials to avoid corrosion and ensure safety.

Whether installed indoors or outdoors, adequate ventilation is a must to maintain the performance and safety of your gas tankless water heater.

Professional Installation vs. DIY

Due to the complexity and specific requirements of tankless water heaters, professional installation is often recommended. Qualified technicians can identify potential issues and ensure that the installation meets all safety standards.

While DIY installation might seem cost-effective, it can lead to problems that could have been avoided with professional expertise.
