Our compact and electrical solution: 85 liters hot bathing water and up to 15 liter of drinking water per day.
WaterStillar Wall is a combination of an electrical traditional water heater and a water distiller. Wall is meant for homes in non-sunny areas of the world and for homes with no access to the sun. Wall is a combination of a distillation apparatus and an electrical water heater, where the distillation process is used to heat bathing water. The heat from the electrical heater is used to evaporate water and this vapor is condensed up against the bathing water tank, giving back the heat energy to the bathing water. Two in one. Wall is built in the best materials available – european stainless steel 316L on the inside and galvanized/powder coated steel on the outside. We have preinstalled both security and check valves, so that installation is easy: Simply connect to the cold and hot water line in your home – and plug it in. The minimalistic design reflects our Danish heritage. The colour is matte white.
Functional design features
- No moving parts, besides 2 valves that fills/flushes the boiler.
- Air and vapour tight design that ensures a sterile environment
- Compact (will fit in a 60 cm wide closet)
- Made from food-grade stainless steel, not causing problems with approvals and no need for anodes
- Thicker insulation (up to 60mm) – less energy loss
- No noise
Working principle and efficiency
WaterStillar Wall distills water at a ratio of 1:1 and is therefore not more efficient than a normal distilling device. The trick is that the initial energy consumption is used twice and the second “effect” is free: you pay electricity for drinking water, but gets hot bathing water as a nice, free bi-product. Or vice versa. And you have only one devise, not two. Your kitchen tabletop can then fit all the other devices, we all have there. As WaterStillar Wall is an on-demand system it is the only device in your home that you need to have bathing and drinking water all year round.
Installation and maintenance
Wall is very compact and will fit in most apartments/houses. The inbuilt drinking water tank can be connected to a dispenser, the fridge or simply a drinking water tap in the kitchen. Wall is using a smaller electrical heater than traditional water heaters and is only available in 230V for now. The heater is controlling the feed water temperature and is working 24/7 to provide enough distilled water for drinking purposes. Total energy consumption is the same as in conventional water heaters for the same amount of hot water. Wall is fitted with a mixing valve, a security valve and room for a carbon/softening filter and is ready to connect to the water line and the hot water line in your house/apartment. The system is pressure tested when leaving our factory and all you need is to connect hot/cold water to your home – and have a single phase 230V power outlet close by. Installation should be done by a certified plumber, but you can do it yourself (local legislation may differ, so please check first). All post treatment-filters, such as mineral filters, are optional. We recommend to buying locally, so that you can get replacement cartridges easily. There is only 1 thing to maintain: Descaling the boiler. Just like your coffe machine needs descaling from time to time. Descaling: If you have calcium above 2-3 dH in your water you need to use a water softening filter to reduce the amount of calcium that enters the boiler. This will keep the intervals of descaling to a minimum. Any coffee machine water softener available locally will do.
Safe and eco drinking water
Unlike other technologies, distillation at high temperatures will produce the cleanest water possible. In combination with an optional carbon filter, you will have endless clean drinking water for decades. Regardless of what is in your feed water – distillation is the safest choice. Having your own drinking water in your home will reduce the number of plastic bottles you will use and throw away. Carrying bottles home and getting rid of the plastic waste is something you can forget about. Convenient and sustainable!
Adding minerals, flavours, syrups, bubbles and cooling down your drinking water is optional. Connect the drinking water to your fridge or install a special drinking water tap at your sink, that will make the installation complete and easy to use.
