Energy Efficiency and User-Friendliness:

The self-modulating valve adjusts the energy needed to heat the water, resulting in significant energy savings. Additionally, it features a gas-saving mode for reduced gas consumption in warmer months. Its modulation makes it ideal for use with mixer taps or thermostatic faucets.

Low Water Pressure Requirement:

Operating at a minimum water pressure of 0.2 bar, the lowest in the market, this water heater is suitable for various applications such as boats, caravans, tiny houses, apartments, or holiday homes.

Safety and Installation:

As an open type gas water heater, the Indoor B-11 requires an exhaust pipe to vent outside and adequate ventilation in the installation area. Various safety features ensure the heater shuts down if exhaust gases are not adequately vented. Manual controls for gas and water flow are provided, and the temperature can be adjusted with the knob.

Automatic Ignition:

Powered by a 1.5-volt battery, the automatic ignition activates when water flows through the unit. The pilot light ignites the main burner when hot water is needed and automatically extinguishes after 60 seconds of no hot water demand, ensuring minimal maintenance after installation.

Featuring ½ inch threaded connections for water and gas, installation of this water heater is straightforward. The unit comes with all necessary components for quick installation.
