Save significant money on your hot water bill by scheduling your hot water cylinder easily as required. Suitable for all electric hot water cylinders and essential for maximising savings for solar installations.
From the EECA regarding solar installs: "If you’ve got an electric hot water cylinder, including a timer in your installation can turn it into a cheap form of energy storage. These devices will pre-heat your hot water while the sun is shining so you can make use of it later. This will save you money as heating water is a large part of most household power bills."
Controlling a HWC has never been easier - switchboard timers are complicated to setup accurately and laborious to change frequently. Being able to control your HWC easily from an app on your phone means you can take full advantage of cheaper tarriffs and special offers from your power authority, ideal for power companies that offer a free hour of power like Electric Kiwi or Contact with their 3 free hours. Or just save money by heating the cylinder once a day instead of everytime someone turns a hot tap on. When correctly installed and setup there should be no difference in water temperature at the tap so there is no danger from bacteria.
