Instantaneous hot water systems, also known as tankless or on-demand water heaters, have been gaining popularity due to their energy efficiency, cost-effectiveness and space-saving design. These systems provide hot water precisely when it’s needed, eliminating the need for a storage tank and the energy waste associated with keeping the tank heated. However, the benefits of instantaneous hot water systems extend far beyond these initial benefits. If you’re thinking of upgrading or installing a new water heater, this article will take a look at six advantages of installing instantaneous hot water systems for providing instant hot water.
Superior Energy Efficiency
One of the most notable features of an instantaneous hot water system is its superior energy efficiency compared to traditional storage tank systems. Storage tank systems continuously heat and reheat water to maintain a ready supply of hot water at the desired temperature. This constant heating process consumes a significant amount of energy. In contrast, instantaneous systems only heat water as it’s needed, not only reducing your carbon footprint, but also lowering your monthly utility bills.
With no need for a bulky storage tank, instantaneous hot water systems occupy significantly less space in your home. Their compact design makes them an ideal choice for smaller properties or households simply looking to optimise their available space. Most units can be conveniently mounted on walls or installed in closets, further enhancing their space-saving potential as well as minimising the degree to which they clash with the design and decor of your home.
Unlimited Hot Water Supply
One of the most appealing benefits of instantaneous hot water systems is the promise of an unlimited hot water supply. Unlike conventional storage tank heaters that can run out of hot water after prolonged use, instantaneous systems can provide hot water indefinitely as long as the tap is running. This ensures you’ll never have to worry about running out of hot water during peak usage times or when hosting guests.
The typical lifespan of an instantaneous hot water system tends to exceed that of conventional units by a decade in some cases. This is due to instant hot water heaters having fewer components that are susceptible to wear and tear over time. With proper maintenance and care, these systems can reliably provide hot water for many years before requiring replacement.
Enhanced Water Quality
Storage tanks can accumulate rust and scale over time, potentially contaminating the stored water. Instantaneous hot water systems circumvent this issue by heating the water directly as it flows through the unit. This ensures you receive cleaner, fresher hot water every time you turn on your tap.
Compatibility with Renewable Energy Sources
Instantaneous hot water systems can work in synergy with renewable energy sources, such as solar power. A solar water heater can provide free heating and storage, while the tankless system ensures hot water on demand. On days when sunlight is insufficient due to weather conditions, the tankless heater can cover any gaps left by the implementation of solar water heating, ensuring a consistent supply of hot water. This combination not only enhances energy efficiency, but also contributes to a more sustainable and environmentally friendly home.
