HydroNova

The space-saving and smart alternative to hot water cylinders

HydroNova is the complete electrical hot water solution. This new way of heating water can be powered directly from Solar PV, making it a carbon-free way of giving your home hot water.

The HydroNova system includes a Thermino© hot water battery from Sunamp©, an innovative new form of heat battery to store heat, which is released only when hot water is needed. So you can charge the system using cheaper rate electricity overnight, or using power from Solar PV during the day and the result is instant hot water from a solution that is also tankless.

The HydroNova system comes with all the components your plumber will need to install it and incorporates Herschel’s smart control switch to allow you to integrate the re-charge cycle with your Herschel Heating and other Smart appliances using the SmartLife App. Once charged this heat can be released instantly, providing you with hot water during peak times, for off-peak prices. Set longer charge times for high-intensity days, or set the HydroNova to holiday mode for those long trips away – optimise your control for maximum efficiency.
