KRAFT&DELE KD11731 Gas Space Heater, 25 kW, with Automatic Thermostat and Regulator

The KRAFT&DELE KD11731 is a 25 kW gas forced-air heater designed for intensive heating of well-ventilated workshops, warehouses, production facilities, garages, and other working environments. The unit operates on propane and butane (LPG), while the integrated fan delivers 320 m³/h airflow to help distribute heat throughout the heated area.

The model features an automatic thermostat that allows users to select the desired temperature. According to the supplier's description, the heater automatically adjusts its operation based on the selected temperature. Its metal construction, included gas hose, and regulator help simplify preparation for use, provided all gas supply and ventilation requirements are followed.

Advantages & Additional Information

• 25 kW heating capacity – designed for intensive heating of larger working spaces.

• Integrated automatic thermostat – allows the desired temperature to be selected and heating cycles to be controlled.

• 320 m³/h airflow – the fan helps distribute warm air throughout the space.

• LPG operation – designed to operate using propane and butane gas.

• Metal housing – suitable for workshop, warehouse, and industrial working environments.

• Gas pressure regulator included – intended to provide the correct gas supply pressure.

• Gas hose included – supplied together with the heater.

• 230 V electrical supply – powers the fan and control system.

Automatic Thermostat and Temperature Maintenance

The KRAFT&DELE KD11731 features an integrated thermostat that allows the desired temperature to be selected.

According to the supplier's description, automatic control adjusts the heater's operation according to the selected temperature. This helps reduce unnecessary continuous heating once the required temperature has been reached.

The exact thermostat adjustment range, automatic ignition operation, and heating cycle controls should be verified in the manufacturer's operating manual.

25 kW Heating Capacity and 320 m³/h Airflow

The heater is designed for applications requiring rapid temperature increases in well-ventilated working environments.

Its 25 kW heating capacity provides intensive heat output, while the 320 m³/h fan airflow helps distribute warm air throughout the area.

Actual heating performance depends on room volume, insulation, initial temperature, outdoor conditions, and the ventilation required for safe operation.

Gas Supply and Pressure Regulator

The KRAFT&DELE KD11731 operates on LPG. The supplier's technical table specifies a gas supply pressure of 0.3 bar (300 mbar).

A gas pressure regulator and hose are included. Before connecting a gas cylinder, verify that the regulator matches the heater's required operating pressure and the intended gas type.

The supplier states a maximum gas consumption of 1.09 kg/h, but this figure should be checked because it may not be consistent with the declared 25 kW heating capacity.

Applications & Usage

The heater is intended for well-ventilated workshops, garages, warehouses, manufacturing facilities, agricultural buildings, construction sites, and other working environments where direct-fired gas heaters are permitted.

The KD11731 can be used for temporary or supplementary heating where high heat output is required and continuous fresh air supply is provided.

Important Safety Information

Safe operation of the KRAFT&DELE KD11731 gas heater requires adequate ventilation.

If the heater is a direct-fired model, combustion products are released into the heated environment, and oxygen is consumed during operation. In this case, continuous fresh air supply is essential.

Do not use the heater in residential living spaces, sleeping areas, or unventilated enclosed spaces unless the manufacturer explicitly permits such use.

Before operation, verify the gas supply pressure, regulator compatibility, leak-tightness of all connections, and the manufacturer's required clearances from combustible materials.
