What is the advantage of a dual element cylinder over a single element cylinder?

1. The Smart Cylinder control method uses a technique called stratification control.
2. This control is much more efficient if the software can decide to heat either the lower (all the cylinder) or just the upper section. The software can still manage stratification with a single element but it is much better with a dual element.
3. Heating recovery is much faster with a dual element cylinder as the upper part is heated first. This makes hot water available rapidly and mitigates any risk of overzealous or ambitious savings settings, even recovery from Holiday mode.
4. Future proof for later upgrades;
   
   • Night Rate (low cost off peak power between 11:00 pm and 7;00 am)
   • Working with Solar Electric installations
