iStore Solar Hot Water System

The iStore system is not a traditional hot water system. It is a thermal energy storage system and an alternative option to far more expensive solar energy storage systems. While already a fantastically efficient solar hot water system on its own, that can save users massive amounts of money every year, the iStore really comes alive when it is paired with a solar hot water system.

Rather than store your excess solar energy for later use with your home's electrical systems like a conventional energy storage system, the iStore uses that excess energy to heat water for your home, leaving it ready for use in your home whenever you might need it.

Far more affordable than most conventional energy storage systems, the iStore represents a fantastic alternative to solar batteries, making excellent use of the energy your solar power system generates that would otherwise go to waste, and saving you money in the process.
