How does a Combi Rainwater Harvesting System work?

Our unique control system combines the benefits of both a gravity-fed header tank system and the pressurised supply of a boosted water system. The simple, compact unit houses a break tank, booster set, and control panel in one easy-to-install unit. All Stormsaver systems come with an automatic back up facility to give you complete peace of mind, even in events of low rainfall.

As well as being our bestselling rainwater harvesting system, the Combi also is specified by many of the top mechanical and electrical contractors in the UK because of the simplicity of the unit.

As with our other systems, rainwater follows the same journey until it reaches the Combi control unit. The rainwater is stored in either a 200L, 400L or 620L internal buffer tank, before being distributed at pressure by either fixed or variable speed, twin booster pumps. As with all Stormsaver systems, there is an automatic, mains water top up to provide a continuous water supply, complying with the guidelines set out by WRAS.

The unit is pre-plumbed and assembled with any BMS connections, automatic backwashing filtration or controls that you may have specified and is fully tested before leaving our manufacturing facility. This will save you time and labour on site, and minimises the likelihood of mistakes being made during the installation.

All of the Stormsaver rainwater harvesting systems will make the most economic use of the local rainfall with predicted water consumption.

It is recommended that you speak to our expert staff to help you choose the correct type of system for your application and that you choose low water consuming products to complement the system, furthering a reduction in overall consumption.
