Floor standing, condensing boiler with built-in 200-liter stainless steel storage tank, connected to the solar circuit.
Nominal heat output: 26,0 kW DHW and 23,6 kW central heating.
It includes all components to be connected to solar collectors for the domestic hot water production.
The 200-liter stainless steel storage tank guarantees a great production of domestic hot water, making HERCULES SOLAR 26 2 ErP the ideal solution in those installation systems where several domestic hot water withdrawals are required at the same time and especially where Jacuzzis are installed. It allows the management of mixed-zones systems, thanks to the wide offer of optional kits that can be directly installed inside the boiler.
The pumps provided as standard with the boiler and the optional ones, along with the kit, are low electric consumption and allow maximum energy savings.
The wide and functional liquid crystals backlit display, allows an easy and immediate visualization of the main functioning information. The advanced electronics allows control of the solar circuit.
Thanks to low emissions of carbon monoxide (CO) and nitrogen oxide (NOX), HERCULES SOLAR 26 2 ErP belongs to class 5, the most environmentally-friendly class established by the European standards (UNI EN 297 e 483).
