The Junkers gas heater ZWR 24-2 KE builds up pressure through a process involving the gas supply and the burner. When the heater is turned on, the gas supply valve opens, allowing gas to flow into the burner. The burner then ignites the gas, creating heat and pressure within the system. This pressure is regulated by the gas control valve to ensure safe and efficient operation of the heater. **
