Revolutionary Eco Heat Technology, Tankless Hot Water System for Commercial Environments and Housing Developments

Herschel’s HydroNova Water Heater System provides hot water, when needed, without the need for tanks.  HydroNova system includes a Thermino© hot water battery from Sunamp* that can be charged via our control system taking advantage of off peak or solar generated electricity. Using patented phase change material, mains pressure hot water is produced as cold water is passed through the battery, providing instant hot water without the need to store large volumes of water.

The HydroNova provides an energy-efficient, simple to install electric water heating solution for domestic properties and well as commercial environments including housing developments, social housing and hotels. Please contact our team for advice and specification.

The HydroNova system comes complete with our controls (HN1 smart switch) and the required components a plumber will need to install it, providing a simple installation process for both retrofit properties and new builds. HydroNova takes up less than a 3^rd of the space of an equivalent domestic water cylinder.

Unlike immersion heaters, HydroNova is a highly efficient system that recharges itself to ensure continual access to heated water and does not ‘run cold’ by the end of the day through heat loss if the hot water isn’t used.

The system is maintenance free and comes with a 10 year warranty.

HydroNova is available in three sizes: 150 PV, 210 PV and 300 PV. They are in litre-equivalent sizes for easy comparison with traditional hot water cylinders.

The HNW-150 (150 litres) is typically enough to service the hot water requirement of a 1 bathroom property, HNW-210 (210 litres) for 2 bathroom** property and HNW-300 (300 litres) for 3 bathroom** property.

HydroNova is solar ready, so if you have (or plan to have) a PV system, you can benefit by charging the system using a solar power diverter (power diverter not supplied). Any PV diverter which is AC Modulating will work, including the following compatible power diverters: 4-Noks power reducer SA, myenergi EDDI solar diverter, my-PV AC·THOR solar diverter, Power Diverter Model 3 solar diverter.

Note that the HydroNova comes with a Herschel Smart Switch, as standard. The Herschel Smart Switch cannot be used alongside a solar diverter. If you are using the HydroNova with a compatible solar power diverter upon install, the Smart Switch accessory will be replaced with an Optimino PV key. Please contact our Logistics team for further assistance. If solar is planned for a future date, the solar PV ready accessory, Optimino key, can be purchased as an additional accessory.
