Investing in an instant hot water system like a tankless or heat pump model saves energy and provides endless hot water on demand. While more expensive upfront, the long term savings on utility bills make it a smart investment.
Tankless water heaters, or instant hot water systems, heat water on-demand and can be powered by gas or electricity. As water passes through a heat exchanger inside the tankless water heater, it is rapidly heated up, ensuring an efficient way to heat water by gas or electricity. This operation avoids the ongoing energy losses typical of traditional hot water systems with tanks that keep water heated constantly.
Due to high electricity costs, Australians are increasingly adopting instant hot water systems for their energy efficiency.
At Werrington Plumbing, we’re experts in the setup to supply hot water, including installation and repair of all major brands of efficient gas hot water system units. We maintain expertise in the latest water heating technologies to offer optimal solutions tailored to our customers’ requirements and finances.
Tankless gas water heaters efficiently channel water through a heating system, eliminating the necessity for a storage tank. As cold water flows through the system, it passes through a heat exchanger, swiftly transitioning into instant gas hot water. Within the heart of the heat exchanger, the gas burners’ pilot light or the electric heating elements are engaged to provide instant gas hot water, swiftly heating the water up to the requisite temperature.
As soon as new hot water is drawn from a tap, the flow sensor optimizes the efficiency of the flow hot water systems by initiating the heating mechanism upon demand, rapidly heating up the water for use. The heat exchanger efficiently transfers heat to the cold water, rapidly heating the water up for a continuous flow of hot water.
Tankless systems generally deliver hot water at over 11 litres per minute up to 75°C, with high-performance models offering flow rates exceeding 19 litres per minute. This capacity enables numerous taps to run at once without a drop in hot water quality.
A controller monitors temperature of the water coming out hot from the system and adjusts the heat output to maintain the preset level. In contrast to storage water heaters, which consume energy continuously, tankless systems are more energy-efficient, using power only when hot water is needed, reducing energy usage by up to 30% compared with tank models.
Instant hot water systems provide key advantages over traditional tank water heaters:
Modern systems, combining high flow rates with energy-saving technologies like solar hot water, deliver efficient hot water on demand.
One of the most appreciated benefits of instant hot water systems is that there’s no waiting for hot water, as their ability to deliver is virtually endless. Families with significant hot water needs can rely on the capable performance of a tankless unit for an unceasing supply.
Storage tank heaters have a finite capacity and hot water supply. Busy households using multiple showers, washing machines, dishwashers and taps simultaneously can rapidly run out hot water due to a standard tank’s limited reserves.
The modern demand water heater marvels at providing warmth without relying on storage hot capacity limitations. The compactness of these units allows for sophisticated heat exchangers that swiftly heat water as needed. This allows numerous outlets in a home to be used at once without diminishing water heating performance or temperature.
Having an endless hot water heater on tap is highly recommended for convenience, especially for large homes. Banish the thought of cold showers or interminable waits for the tank to reheat—you can have a perpetual supply of warmth with instant hot water, ready for use the next day and beyond. Tankless heaters deliver a steady stream of hot water on demand, ensuring comfort and peace of mind.
A major advantage of instant hot water systems is their lower energy consumption, enhancing efficiency compared to storage tank models. By eliminating the need to constantly maintain a tank of hot water, instant systems avoid heat losses of around 20% or more that occur 24/7 in traditional heaters.
Research indicates that gas tankless units are 20-30% more energy-efficient than storage tank models, cutting down on gas usage. Spanning across an average 15-year lifespan, this equates to an annual saving, with a Werrington homeowner keeping between $2,500 to $4,500 in their pockets per year, contingent upon their use of instantaneous hot water.
Modern electric hot water systems, especially those paired with solar technology, achieve even higher efficiency, yielding energy savings of 27%-60%. Choosing an electric tankless system can lead to savings of $3,500 to $7,000 for the average household over the equipment’s lifespan.
Amid rising energy costs in NSW, more households are opting for gas tankless water heaters due to their efficiency and potential cost savings. By only heating water on demand, a new hot water system can now be a more affordable option compared to traditional tank systems.
Before installing an instant hot water system, consider some crucial factors:
Werrington Plumbing can recommend the ideal instant hot water system tailored to your home’s needs and budget. We provide comprehensive services for hot water and air conditioning, delivering efficient, cohesive solutions for your home’s utilities.
Although they come with many benefits, instant hot water systems have a higher initial cost compared to traditional tank water heaters. The cost for a gas instantaneous model suitable for the average household ranges between $1,200 and $2,500. Compact electric whole home tankless units start around $2,000 rising to $3,500 or more.
Installation costs are comparable for gas systems, but your system may require expensive upgrades to power supply, wiring and switches to handle the high amp load if you opt for electric hot water units. Additional plumbing work adds $500 or more regardless.
When it comes to reducing wasteful standby losses and heating your water on demand, Australians can recover the extra upfront costs within 5 years for gas hot water systems or 2-4 years with efficiency of electric storage units compared to tankless alternatives.
Although tankless water heaters have numerous advantages, they might not suit homes with exceptionally high hot water demands, where the capacity of even the most robust systems might be challenged.
Ensuring an uninterrupted supply for such homes may require either several compact tankless units or a large central system. This adds considerably to upfront equipment and installation costs. Running multiple units simultaneously also increases energy use.
Homes in cooler climates can experience issues getting instant gas systems up to temperature during winter. Extra insulation or perhaps a more suitable storage system with hybrid capabilities might address the warmth requirements efficiently.
The specialists at Werrington Plumbing can examine the specific characteristics of water your home uses and its existing plumbing fixtures to determine if an instant hot water system is the smartest, most efficient, and cost-effective solution for you.

Selecting the right size instant hot water system is essential for peak performance. Sizing refers to the heating capacity and flow rate of the unit.
Generally, gas instantaneous systems need around 24kW (80MJ/h) heating power to supply continuous hot water to the average home with 2 bathrooms. Larger homes should scale up to 27kW or even 34kW models.
Compact electric whole home systems require 18kW to 27kW for uninterrupted hot water. Point-of-use units as small as 6kW can supply a single tap.
The flow rate is crucial. Select models with a rate of 18-25 litres per minute for high simultaneous use, or consider linking multiple smaller units.
