About solution
Therm 4000 O WR 10-2 B Gas tankless water heater ensures user-friendly operation, requiring a simple press of a button to initiate readiness. The electronic ignition system activates automatically upon opening the hot water tap.
- Power modulation
- Separate power and water flow control
- Connects to an existing chimney
- The heater switches on automatically when the tap is opened
- The minimum required operating water pressure is 0.1 atm.
Technical equipment
- Electronic ignition from batteries
- Automatic maintenance of temperature and water flow rate when the water pressure in the water supply system changes
- Ionization electrode for flame control
- Temperature limiter that protects the heat exchanger from overheating
- Draft control device with automatic column shutdown
- Atmospheric gas burner made of stainless steel with the possibility of switching to LPG operation
- Tin-free copper heat exchanger with a service period of 15 years
