14 liters per minute propane gas water heater with battery ignition, 30-37 mbar


The new TTulpe® Indoor B-14 Eco is an open modulating propane gas water heater designed for indoor installation. With a capacity of 14 liters per minute, this heater provides efficient and reliable hot water supply for various applications.

Energy Efficiency and User-Friendliness:

The self-modulating valve adjusts the energy amount needed to heat the water, resulting in significant energy savings. Additionally, it features a gas-saving mode for reduced gas consumption during warmer months. The heater is well-suited for use with mixer taps or thermostatic faucets.

With a minimum water pressure of 0.2 bar, this water heater is suitable for situations with low water pressure, making it versatile in its applications.

Safety and Installation:

As an open type gas water heater, the Indoor B-14 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. The unit features manual controls for gas and water flow, and the temperature can be adjusted with a dial.

Automatic Ignition:

The heater comes with an automatic ignition powered by a 1.5-volt battery. This ignition activates when water flows through the unit. The pilot light ignites the main burner when hot water is needed, and it automatically extinguishes if there's no hot water demand for 60 seconds.

Featuring ½ inch threaded connections for water and gas, installation of this water heater is straightforward. All necessary installation components are included with the unit.
