How Flow Loop’s Circular Shower System Transforms Water and Energy Use
Discover Flow Loop’s innovative recycling shower: save up to 85% water and 75% energy while enjoying an upgraded shower experience.
Rethinking Showering: Meet the Flow Loop Circular Shower System
Modern households face increasing pressure to conserve resources, particularly water and energy. Standard showers, though more efficient than baths, still let most of their heated water—and the energy used to heat it—drain away unused. Flow Loop, a Danish innovation, reimagines this daily routine, delivering impressive savings and an enhanced showering experience without sacrificing comfort.
- Reduces water use by up to 85%
- Cuts shower-related energy consumption by 75%
- Easy retrofitting into most existing bathrooms
- Advanced purification ensures safety and comfort
- Instant rainshower experience with minimal maintenance
Why Showers Need a Sustainability Upgrade
Showers account for as much as 40% of water consumption in the average home. In hotels and other high-occupancy buildings, this number can be significantly higher. Standard showers use about 9–10 liters of water per minute, meaning an average eight-minute shower sends around 80 liters of warm water down the drain.
This wasted warm water includes both water and the energy it took to heat it. According to Flow Loop, heating shower water constitutes 25% of a typical household’s heating cost, contributing to 80% of its hot water demand. With utility costs on the rise and freshwater scarcity looming in many regions, these numbers highlight the urgent need for smarter solutions.
How Flow Loop’s Circulating Shower Reduces Waste
The engine of Flow Loop’s innovation is its closed-loop circulation system. Here’s how it works:
- Used water is collected from the shower floor.
- This water is micro-filtered and passed through an ultrasonic descaling system and UV light disinfection chamber for purification.
- The freshly purified water is then re-circulated directly back to the shower head.
- Only one liter of fresh warm water per minute is added, maintaining temperature and proper rinse-off.
The result: The entire shower uses just 8 liters of new water instead of the usual 70–80, without sacrificing comfort or hygiene.
An Overview of the Technology
| Flow Loop Feature | Function |
|---|---|
| Micro-filtration | Removes particulate impurities on every pass |
| Ultrasonic descaling | Breaks down mineral scale, maintaining clean pipes and water |
| UV Light Disinfection | Neutralizes bacteria and microorganisms, ensuring high water safety |
| Recirculating Pump | Continuously returns purified water to the shower head |
| Temperature Mixing | Adds minimal fresh warm water to retain optimal shower temperature |
The Environmental and Financial Benefits of Flow Loop Showers
- Water savings: Cuts water use by up to 85% per shower, protecting local freshwater resources.
- Energy savings: Recirculated water retains most of its heat, reducing energy demand by 75% versus standard showers.
- Lower utility bills: Households and businesses benefit from immediate reductions in both water and energy costs.
- Reduced carbon footprint: Lower energy use for water heating translates into fewer greenhouse gas emissions.
For example, a regular shower lets used water go down the drain at around 35°C, but Flow Loop’s system recirculates it at 38°C, retaining more of the heat generated and maximizing each watt used.
Designed for Comfort and Convenience
A key barrier to sustainable technology adoption is ease-of-use and performance. Flow Loop addresses this with:
