Water flows through both cells simultaneously, providing a flow rate of 3,000 litres per hour. When one cell becomes saturated, it regenerates using brine from the salt supply while the other cell takes over the softening process. You will not notice the change: there is no point at which hard water comes from the tap. During regeneration, the single active cell still supplies 1,800 litres per hour, which is more than sufficient because an average shower uses 8 to 12 litres per minute.\u003c\/p\u003e\n\u003cp\u003eRegeneration is volume-controlled and uses an upflow process: each cell regenerates after approximately 700 litres of treated water. At a water hardness of 11 °dH, this equals a capacity of approximately 7.7 °dH·m³ per regeneration. For a four-person household, this amounts to around 257 regenerations per year. Because the AquaCell operates on water pressure, it requires no electrical socket and its electricity cost is exactly zero.\u003c\/p\u003e\n\u003ch3\u003eWho is the AquaCell suitable for?\u003c\/h3\u003e\n\u003cp\u003eCulligan deliberately offers one model instead of multiple capacities. It is suitable for households ranging from one person to approximately eight people at one address. Because the system regenerates according to volume, it adapts to actual consumption: the more water you use, the more frequently it regenerates. More than 325,000 people worldwide now own an AquaCell.\u003c\/p\u003e\n\u003ch3\u003eWill I notice a difference in water pressure?\u003c\/h3\u003e\n\u003cp\u003eHardly at all during normal household use. At a shower flow rate of 8 to 12 litres per minute, the pressure drop is less than 0.2 bar. The pressure drop only reaches 0.9 bar at 30 litres per minute, which is more than the 25 litres per minute allowed by a standard water meter. In short: if your water pressure is currently sufficient, it will remain so.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth\u003eSpecification\u003c\/th\u003e\u003cth\u003eValue\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eSystem type\u003c\/td\u003e\u003ctd\u003eDuplex ion exchanger, two cells operating in parallel, volume-controlled\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eSoft water during regeneration\u003c\/td\u003e\u003ctd\u003eYes, the second cell takes over\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eResin volume\u003c\/td\u003e\u003ctd\u003e8.6 litres in total\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegeneration per cell\u003c\/td\u003e\u003ctd\u003eAfter approximately 700 litres of treated water\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCapacity per regeneration\u003c\/td\u003e\u003ctd\u003eApproximately 7.7 °dH·m³, calculated from 700 litres at 11 °dH\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eFlow rate, both cells\u003c\/td\u003e\u003ctd\u003e3,000 l\/h, equivalent to 50 l\/min\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eFlow rate during regeneration\u003c\/td\u003e\u003ctd\u003e1,800 l\/h, equivalent to 30 l\/min, through one cell\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePressure drop\u003c\/td\u003e\u003ctd\u003eLess than 0.2 bar at 8–12 l\/min; 0.9 bar at 30 l\/min\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eWater used per regeneration\u003c\/td\u003e\u003ctd\u003e23 litres\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eAnnual water consumption\u003c\/td\u003e\u003ctd\u003e5.6 m³ for a four-person household, approximately 3% extra\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegenerations per year\u003c\/td\u003e\u003ctd\u003eApproximately 257 at annual consumption of 180 m³ and 11 °dH\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegeneration time\u003c\/td\u003e\u003ctd\u003eAverage of 15 minutes; 11–20 minutes depending on incoming pressure\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegeneration direction\u003c\/td\u003e\u003ctd\u003eUpflow\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eResidual hardness\u003c\/td\u003e\u003ctd\u003e0 °dH, completely limescale-free water\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eSalt type\u003c\/td\u003e\u003ctd\u003eHigh-purity salt blocks with no added chemicals\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eAnnual running costs\u003c\/td\u003e\u003ctd\u003eApproximately €130: €125 for salt, €5 for rinse water and €0 for electricity\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eElectricity\u003c\/td\u003e\u003ctd\u003eNone; operates entirely on water pressure\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eWater pressure\u003c\/td\u003e\u003ctd\u003e1 to 8 bar\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eConnection diameter\u003c\/td\u003e\u003ctd\u003e19.05 mm\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eDimensions (H × W × D)\u003c\/td\u003e\u003ctd\u003e49 × 20.5 × 44 cm\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eWeight\u003c\/td\u003e\u003ctd\u003e20 kg empty; 30 kg in use\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNoise level\u003c\/td\u003e\u003ctd\u003e41 dB during regeneration\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMaterial\u003c\/td\u003e\u003ctd\u003e68% recycled material\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eSmart functions\u003c\/td\u003e\u003ctd\u003eSalt sensor with app notification; accurate enough to detect a dripping tap\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCertification\u003c\/td\u003e\u003ctd\u003eKIWA to BRL-K14022 and Dutch regulations for materials and chemicals in drinking and hot tap water, plus WRAS\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eWarranty\u003c\/td\u003e\u003ctd\u003e5-year all-in service, 15-year parts warranty and 30-year resin warranty\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePrice\u003c\/td\u003e\u003ctd\u003e€2,348 at PureAqua\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat does the AquaCell cost to run?\u003c\/h3\u003e\n\u003cp\u003eFor an average four-person household using 180 m³ of water per year at 11 °dH, Culligan estimates annual costs of approximately €125 for salt and around €5 for rinse water. Electricity costs nothing because the AquaCell operates on water pressure. Total running costs are therefore approximately €130 per year. Including purchase, installation and service over fifteen years, the overall cost is approximately €200 to €250 per year.\u003c\/p\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the AquaCell also supply soft water during regeneration?\u003c\/strong\u003e\u003cbr\u003eYes. This is the difference compared with a single-cylinder system. The AquaCell has two cells: while one regenerates, the other continues softening. You therefore have soft water 24 hours a day, with 1,800 litres per hour available during regeneration instead of 3,000.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the AquaCell require electricity?\u003c\/strong\u003e\u003cbr\u003eNo. The AquaCell operates entirely on water pressure between 1 and 8 bar. No electrical socket is needed near the water meter and annual electricity consumption is zero. It continues to operate during a power cut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much rinse water does the AquaCell use?\u003c\/strong\u003e\u003cbr\u003eIt uses 23 litres per regeneration. For a four-person household consuming 180 m³ per year, that means approximately 257 regenerations and 5.6 m³ of rinse water: around 3% above normal consumption and approximately €5 per year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many people is the AquaCell suitable for?\u003c\/strong\u003e\u003cbr\u003eIt is suitable for households from one person to approximately eight people at one address.

The AquaCell has KIWA approval under assessment guideline BRL-K14022 for appliances that treat drinking and hot tap water, including the relevant hygiene requirements. The European NEN-EN 14743+A1 standard for water softeners forms part of this. The AquaCell is also WRAS certified.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference compared with Joep?\u003c\/strong\u003e\u003cbr\u003eThe AquaCell has two cells and therefore supplies soft water during regeneration; Joep has one cylinder and regenerates at night. The AquaCell operates without electricity, while Joep uses a 12 V adapter. At €1,699, Joep is considerably less expensive and publishes its salt consumption in kilograms; the AquaCell is more compact and offers longer warranty periods.
