solar powered
Imagine a system that you buy/install and have running for decades giving you all the hot water and drinking water your family will need - not using anything else than solar power.
​
At the same time you can trust WaterStillar to provide the cleanest water, regardless of what may be in your water in future.
​
Transportation and plastics goes out of the equation about drinking water - and CO2 for the hot water you use every day.
​
WaterStillar Family is built to last. That is the key to respect ressources of which we soon run out. Buy once.
Clean
Distillation is state of the art water cleaning. No other technology can make as clean water and remove as many contaminants as distillation.
​
On top of that, our design ensures no biofouling or migration of contaminants back into the water. We expect it to work for decades - and the design guartees sterile drinking water inside from day 1.
​
If you prefer minerals in your water, you simply add one or more remineralization cartridges in the pipe between WaterStillar and your tap.
​
We do not only claim, we take pride in knowing. Please check our database of contaminants and see how WaterStillar performs compared to filters, UV and carbon.
Installation
WaterStillar Family is installed like any other solar heater, but there is an extra tube with the drinking water going down to the kitchen.
​
If you have a flat roof or a place on the ground for the system, all it needs is sun. On the roof, gravity will make the drinking water flow - other wise a small pump will send the drinking water to yor faucet.
​
The hot water is connected to a cold line and out comes the hot water. The cold water is also used for distillation.
​
No worries about noise. WaterStillar Family is completely silent. It has no moving parts inside.
​
​
(Sun)bathing
In sunny areas of the world, heating your bathing/cleaning water is a big cost for a family. With a WaterStillar Family you get hot water for free, so we promise that your bath will be more enjoyable.
​
The insulated tank will store the heat inside for days, so if you have sun on a Monday, you can still have a hot bath on a Wednesday.
​
WaterStillar family can be fitted with an electrical heater, so that it may be the only hot water / drinking water source you'll ever need.
​
The hot water is not distilled. It is just heated. The distilled water is stored inside in a seperate tank. It is impossible for those 2 to ever mix.
​
Unlike other solar heaters, WaterStillar Family by design will never boil and break from overpressure. Guaranteed. Even without a security valve.
10 reasons to choose Family
1) FREE YOUR KITCHEN TABLE TOP
Family is a solar hot water tank, that typically lives on your roof. Only thing you’ll have in your kitchen is the special faucet, where you get your drinking water.
2) DISTILLED, NOT FILTERED
Filters reduce contaminants, distillation eliminates them.
3) NO ENERGY
Family is a hot water tank running on solar power and will in sunny places not have the need of an electrical back-up. The distilled drinking water is a free bi-product to your hot bathing water.
4) STERILE AND NO LOSS OF EFFICIENCY FOR DECADES
Family is designed in such a way that the drinking water tank will remain sterile. No cleaning necessary and the water cleaning capabilities are the same for decades.
5) NO WASTE. NO PLASTIC. AT ALL.
Family has no bi-flow like filters and there is no plastic in the construction, migrating questionable chemicals back into the water. Even the mandatory activated carbon is made of stainless steel and refillable.
6) LONG LIFESPAN - ANALOGUE
Family has been built in the best materials available and should last for decades. The design has no moving parts.
7) FAMILY CAN NOT OVERHEAT AND BOIL
Unlike conventional solar heaters, Family can not overheat and cause boiling that eventually may break the tank(piping in your house.
8) ALMOST MAINTENANCE FREE
Family has an optional automated flush, a simple valve and a timer. It will need descaling from time to time. Just like a coffee machine. Every 6-12 months the activated carbon needs to be refilled (10 min job) - and that is it. The system will notify you.
9) DESIGN YOUR OWN WATER
Once the drinking water is clean, you can add anything to it. Minerals, flavors, bubbles, You can cool it. Or just drink it as it is.
10) NO HIDDEN, RECURRING COST
Once you have bought a Wall, your drinking water is free. We do not have any cartridges or service cost that you are forced to buy from us. In certain markets there may be an option to let WaterStillar come by every 6-12 months to do maintenance - but it is your choice.
Carbon footprint
WaterStillar Family is exected to last +20 years and in that time it will provide hot bathing water and clean drinking water - 100% powered by the sun.
​
Each WaterStillar Family will save between 22 and 94 tonnes of CO2 in these 20 years.
​
The wide spectrum is the differences in what kind of energy is being used to produce a kWh of energy and the travel distance for the bottled water in question.
