Hydro Silver

Convenient dual-function boiler with a pellet feeder

Hydro Silver is a boiler based on the technologically advanced product, Eko Silver III. Thanks to its increased water capacity, which acts as a heat buffer, operating and installation costs are significantly reduced as there is no need to install a domestic hot water (DHW) pump.

The boiler is equipped with a copper, antibacterial coil that ensures a reliable supply of domestic hot water. The automatic heat exchanger and pellet burner cleaning function increases user convenience, making the Hydro Silver central heating boiler a solution that combines efficiency and comfort.

Coil Efficiency

The coil provides a flow rate of 1.2 to 1.5 m³/h, allowing for a power output of 49 to 61 kW.

Approximate amount of available domestic hot water:

• 10kW - from 120 to 175 liters
• 15kW - from 120 to 190 liters
• 20kW - from 125 to 195 liters
• 25kW - from 140 to 220 liters
• 40kW - from 215 to 300 liters

The amount of prepared water depends on the boiler water temperature settings (60-70°C).
