High-Efficiency Water Softening with Lower Regeneration Waste
A whole-home metered water softener designed for hard water, elevated dissolved iron and households that want strong performance with lower salt and regeneration-water use.
- Up to 30% less salt than conventional softener designs
- Up to 5× less water used during regeneration
- Softens hard water and reduces dissolved iron
- 10-year manufacturer warranty
Why Choose the Aquaphor S800?
Lower Salt Use
Fine-mesh resin and efficient regeneration reduce salt demand compared with conventional designs.
Less Regeneration Water
Aquaphor's Dual Core valve design is engineered to minimise the water discharged during regeneration.
Fine-Mesh Resin
A high-capacity bed of tightly packed, chlorine-resistant ion-exchange resin provides a large treatment surface.
Service Flow
Specified service flow at approximately a 1 bar pressure drop for everyday whole-home use.
Reduce Limescale Throughout the Property
The S800 removes the calcium and magnesium hardness minerals responsible for limescale. Installed on the incoming mains supply, it provides softened water throughout the home.
This helps reduce scale around taps and showers while protecting boilers, cylinders and water-using appliances from ongoing mineral build-up.
- Helps protect heating and hot-water equipment
- Reduces scale in kettles and household appliances
- Less visible limescale around bathrooms and kitchens
- Metered regeneration based on actual water use

Hardness and Dissolved Iron Treatment in One System
The S800 combines conventional hardness reduction with the ability to reduce elevated dissolved ferrous iron. Aquaphor markets the system for iron concentrations up to 15 ppm, while its published technical specification lists a 12 ppm ferrous-iron reduction rating.
Hardness Reduction
Reduces dissolved calcium and magnesium responsible for hard-water scale.
Iron Reduction
Designed for water with elevated dissolved iron, subject to incoming water chemistry and installation conditions.
NSF/ANSI 44
Aquaphor states that the system conforms to NSF/ANSI 44 for specified performance claims.
Designed to Use Less Salt and Less Water
The S800's compact resin bed and patented Dual Core valve architecture are designed to improve contact between the water and ion-exchange media while reducing the resources required during regeneration.
Check the Space and Plumbing Before You Order
The S800 has a larger cabinet than the S550, but remains compact for a 23-litre resin system. Allow clearance for the plumbing connections, drain, power supply and routine salt replenishment.
What the S800 Needs
Incoming Mains Supply
Install on the incoming water supply where whole-home softened water is required.
Drain Connection
A drain is required for regeneration discharge, with a minimum 16mm / 5/8-inch drain line.
Electrical Supply
The metered controller requires a suitable nearby power supply.
Operating Pressure
Aquaphor specifies an operating pressure range of approximately 1.4 to 7 bar.
Temperature Range
Designed for water and ambient temperatures from approximately 5°C to 38°C.
Salt Access
Leave enough clearance above and around the cabinet for salt top-ups and routine servicing.
