10.8 L/min Instantaneous LPG Hot Water

The Pegaso Eco 11 is an instantaneous LPG water heater, meaning water is heated as it passes through the appliance rather than being stored in a hot-water cylinder.

Ferroli specifies:

• 10.8 L/min at ΔT25°C
• 9 L/min at ΔT30°C

The actual flow available at the outlet depends on factors including incoming cold-water temperature, water pressure and the selected hot-water temperature.

21.1 kW LPG Gas Water Heater

The Ferroli Pegaso Eco 11 has a manufacturer-specified maximum heat capacity of 21.1 kW.

Its maximum useful output is 18.9 kW, while the minimum heat capacity is 8.1 kW and minimum useful output is 7.0 kW.

This makes the Pegaso Eco 11 a higher-output option within the Pegaso Eco range compared with the Pegaso Eco 6.

LPG Operation

The Pegaso Eco 11 is available in an LPG version.

Ferroli’s technical information specifies a 37 mbar G31 supply pressure for the LPG configuration.

Always verify the exact gas configuration, local gas requirements and approved installation conditions before installation.

Designed for Static Caravans

The Pegaso Eco range is particularly associated with static caravan hot-water installations.

Ferroli states that the units should only be installed where there is a suitable fixed cold mains water supply. The manufacturer also warns that the Pegaso units may not be suitable for boats, touring vans and motorhomes.

Potential approved applications may include:

• Static caravans
• Suitable holiday accommodation
• Caravan park installations
• Approved LPG hot-water installations
• Other applications permitted by Ferroli and local regulations

Always confirm suitability for the specific installation.

Class 6 Low-NOx Technology

The Ferroli Pegaso Eco 11 is classified as a Class 6 Low-NOx gas water heater.

Ferroli’s technical data identifies the appliance as Class 6 and lists NOx emissions below 72.8 mg/kWh for G31/G30.

This makes the NOx classification an important specification for customers comparing modern LPG water heaters.

Battery-Powered Electronic Ignition

The Pegaso Eco 11 uses battery-powered electronic ignition.

Ferroli specifies a 3 V battery supply, meaning the ignition system does not require a conventional 230 V mains electrical connection.

The manufacturer describes the appliance as using a compact water-cooled burner with electronic ignition.

Modulating Heat Output

The Pegaso Eco 11 uses modulating heat output and provides adjustment of power and hot-water temperature.

This allows the appliance to operate across its specified output range rather than operating only at a single fixed heat level.

Copper Heat Exchanger

The Ferroli Pegaso Eco uses a copper heat exchanger with an external aluminium anti-corrosion treatment.

The construction forms part of Ferroli’s design for the Pegaso Eco instantaneous water-heating range.

Compact Wall-Mounted Design

The Pegaso Eco 11 is designed as a compact wall-mounted water heater.

Ferroli’s technical data lists an empty weight of approximately 9.5 kg for the Pegaso Eco 11 and a protection rating of IPX4D.

Water Pressure

The manufacturer specifies:

• Minimum operating water pressure: 0.2 bar
• Maximum operating water pressure: 10 bar

The actual installation must meet Ferroli’s requirements and applicable local regulations.

Maximum Hot-Water Temperature

Ferroli specifies a maximum working temperature of 65°C for the Pegaso Eco 11.

The actual outlet temperature should be set according to the installation requirements and intended use.

Ferroli Pegaso Eco 11 vs Pegaso Eco 6

The Pegaso Eco range includes the Pegaso Eco 6 and Pegaso Eco 11.

The Pegaso Eco 11 provides the higher hot-water flow:

Pegaso Eco 11

• 10.8 L/min at ΔT25°C
• 9 L/min at ΔT30°C
• 21.1 kW maximum heat capacity
• 18.9 kW maximum useful output

Pegaso Eco 6

• 6.0 L/min at ΔT25°C
• 5.0 L/min at ΔT30°C
• 11.8 kW maximum heat capacity
• 10.4 kW maximum useful output

Therefore, the Pegaso Eco 11 is the more appropriate choice when the installation requires greater instantaneous hot-water flow.
