Domestic rainwater harvesting systems can save up to 50% of water consumption within the average home. Water can be used for toilet flushing, washing clothes, garden watering and car washing.
The RainSava domestic rainwater harvesting range offers a number of system options. Direct fed systems are the most popular due to their simplicity; in this range we offer the “Classic”, “Eco Pro” and “Sigma” systems. All use either our WISY® Vortex filter, the finest rainwater filter on the market, or the new LineAr low profile filter, and our unique high-flow mains water top-up unit.. The Eco Pro system offers the user lower power consumption, built in system diagnostics, and easier system monitoring from the advanced control unit.
For those seeking a lower cost option, then look at our RainSava Classic that uses a simple automatic pump with inbuilt controller.
The Sigma unit is our unique WRAS-Approved rainwater module suitable for most domestic properties and particularly good for retro-fit in to existing buildings.
Completing the range we also have our Gravity system utilising a compact and reliable header tank.
Highly reliable, simple, and safe!
