Gjosa GS3

frequently asked questions

(FAQs)

How does the Gjosa GS3 save water?

The GS3 uses Swiss-engineered Jet-Fusion Technology to mix air and water at high speed, creating a powerful yet gentle spray. It delivers just 4.5 litres per minute, compared to the 12 L/min of a standard showerhead, saving you up to 65% of water with every shower.

How does the Gjosa GS3 save energy?

Because you’re heating far less water per shower, your boiler or water heater doesn’t need to work as hard. That means lower energy bills and a smaller carbon footprint, all without sacrificing comfort.

Will it wash off my long hair properly?

Absolutely! Despite using less water, the GS3’s Jet-Fusion spray produces high-velocity droplets that rinse shampoo and conditioner effectively, even for thick or long hair. No misty trickle, just a full, satisfying rinse.

Is it like a mist or a normal shower?

It’s not a drizzling mist, it’s a very powerful “mist-like” shower experience with a steady, refreshing flow. The spray feels soft on the skin but strong enough to wash thoroughly. Most people are surprised how powerful it feels given how little water it uses.

Is it as warm as a regular shower?

The showerhead is designed for close-range use, where the water temperature feels consistent. If it’s held further from the body, some users notice the heat dissipates slightly. In those cases, we recommend increasing the temperature a little for optimal comfort.

Does increasing the temperature use more energy?

It might seem like it would, but no, not as long as you’re not using more water. You’re simply mixing in less cold water, not consuming additional energy, so overall usage stays the same.

What is Jet-Fusion Technology?

It’s a patented Swiss innovation that blends air with water micro-droplets through a precision-engineered nozzle system. This boosts the water’s velocity and coverage, giving you a full shower while using far less water.

Does it improve water pressure?

While it doesn’t increase actual pressure, if your water pressure is already low, the GS3 can actually make it feel higher thanks to its optimised spray pattern.

Does it work better when handheld or fixed on the wall?

The GS3 gives the most comfortable experience when used handheld, as the spray performs best closer to your body. This helps maintain warmth, improves coverage and delivers the full effect of the micro-droplet technology. It can also be used in a fixed mount. For the best results in this setup, we suggest positioning it slightly lower, around shoulder height, so the spray remains closer to you and heat is not lost before it reaches the body.

How can I save money with this showerhead?

By reducing both your water and energy use, the GS3 can save a household up to £200 per year (depending on shower habits and local utility rates). It pays for itself within months, and keeps saving year after year. If you’re a business managing multiple bathrooms, the savings add up even quicker yielding up to 5 figure savings annually.

Will my partner or family like it?

Almost certainly yes! Many couples are surprised that it feels more spa-like than their old showerhead. It’s water-saving and comfortable, a rare win-win for both sustainability and enjoyment.

Is it easy to install?

Yes, it fits standard shower hoses and connectors. You can install it in under a minute without any tools.

Can I use it with my existing water heater or combi boiler?

Definitely. The GS3 works with all common systems, just make sure your water pressure is at least 2 bar for optimal performance.

Does it work with electric showers?

No, unfortunately the GS3 isn’t compatible with electric showers. It’s designed to work best with mixer or thermostatic systems.

Is there any maintenance required?

If you live in a hard-water area, just clean it occasionally with a descaler, the same way you’d clean your current showerhead. That’ll keep it performing like new.

How much water pressure is needed for the GS3 to achieve the best savings?

The GS3 performs best at around 2 bar pressure. That’s the sweet spot where you’ll get the perfect balance of water savings (up to 65%) and a satisfying shower experience.

Does it have different spray modes?

No, the GS3 is designed with one optimised spray mode that delivers the ideal balance of comfort, coverage, and water savings. It’s precision-engineered so you get the best performance without needing to switch settings.
