If you’re looking to access top quality clean water in your home or business, then a filtration system can make all the difference. In particular, reverse osmosis water purification systems provide a superior level of filtration, removing dissolved solids, harmful metals and other contaminants that can affect the taste and smell of your drinking water.

Reverse osmosis systems have come a long way since their initial invention, where you can now install a tankless system that fits easily beneath your kitchen sink. These filtration systems are easy to install and take up minimal room, so you can enjoy the benefits of filtered water without rearranging your space.

Read on to find out more about tankless reverse osmosis systems, with a look at why these units represent the future of filtration technology.

What is a Tankless Reverse Osmosis System?

A tankless reverse osmosis (RO) unit is a modern and compact type of water filtration system that provides purified drinking water on demand without the need for a storage tank.

Unlike traditional reverse osmosis systems that rely on a tank to store purified water, tankless systems filter water instantly as you need it. This means you don’t have to wait for a tank to fill up, and you don’t have to worry about stale water or bacteria growth in your storage tank, which is why it is advised to replace the tanks every 5 years. Instead, you get fresh, purified water every time you turn on the tap.

Tankless reverse osmosis systems typically use a multi-stage filtration process. First, a sediment filter removes larger particles like dirt and rust. Then, a carbon filter reduces chlorine, odours, and other contaminants that affect the taste and smell of your water. 

The heart of the system is the reverse osmosis membrane, which filters out a wide range of impurities, including heavy metals, microplastics, fluoride, dissolved solids, microorganisms and much more. A high-efficiency pump provides the pressure needed for this process, eliminating the need for a storage tank. Finally, a polishing filter further refines the water for improved taste and clarity.

The Environmental Benefits of Tankless RO Installations

Tankless reverse osmosis (RO) systems are gaining popularity not just for their space saving qualities, but also for their positive impact on the environment. These systems contribute to a greener planet in the following ways:

Reduced Water Waste

Traditional RO systems with storage tanks are known for their high water wastage.  For every litre of purified water produced, several can be wasted as the system flushes out contaminants. 

Tankless RO systems, on the other hand, are much more efficient. They generate significantly less wastewater, as they purify only when needed, eliminating the need for constant flushing and tank refills.

For example, traditional RO systems would waste approximately 3 – 4 litres of water to produce 1 litre of pure water. Tankless systems, specifically the Hommix hydRO, only wastes 700ml (0.7 litres) to produce 1 litre of pure water. 

Lower Energy Consumption

Tankless RO systems also don't require energy to keep a tank full of water, unlike traditional systems. This translates to lower electricity bills and a reduced carbon footprint. While they do use energy to power the pump during water filtration, overall energy consumption is still lower compared to tank-based systems. 

On average, these pumps use approximately 25 watts. Here’s a quick calculation:

Power consumption: 25W

Electricity price: £0.27 per kWh (average UK cost at the time of this article)

If used for 60 minutes a day (usually a lot less) at full capacity, this would give you the following electricity usage and costs: 

Space-Saving Design

The compact design of tankless RO systems means less plastic is used in their manufacturing. This reduces the environmental impact associated with the production and disposal of bulky plastic tanks.  

Longer Lifespan

With fewer components and a more streamlined design, tankless RO systems tend to have a longer lifespan compared to traditional models. This reduces the need for frequent replacements, further minimising waste and resource consumption.

Encourages Use of Filtered Water

By providing instant access to purified water, tankless RO systems encourage people to drink filtered water instead of bottled water. This helps reduce plastic waste and the environmental impact associated with the production and transportation of bottled water.

Why Tankless Systems are the Future

Tankless systems represent the future of water filtration, offering a compelling combination of convenience, efficiency, and improved water quality that makes them a superior choice compared to traditional tank-based systems. 

Some of the benefits of choosing a tankless model include:

Space-saving design: Traditional RO systems with tanks can be bulky, taking up valuable space under your sink. Tankless systems eliminate this problem with their compact design, freeing up space for storage.

Fresh, purified water on demand: With a tankless system, you get purified water instantly whenever you need it. No more waiting for a tank to fill up, and no more concerns about stale water sitting in a tank.

Improved water quality: By providing instant filtration, tankless systems reduce the risk of bacterial growth that can sometimes occur in storage tanks. This ensures you always get the purest, cleanest water possible.

Easy installation and maintenance: Tankless systems are generally easier to install and maintain, with simpler filter changes and fewer components to worry about.

Smart features: Many tankless RO systems come with advanced features like filter life indicators, TDS meters, and leak detectors, providing greater control and convenience.
