About solution
Therm 4000 O WR 10-2 P 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 (for models with WR index)
- Separate control of power and water flow
- Connects to an existing chimney
- Constantly burning pilot light
- The minimum required operating water pressure is 0.1 atm.
Technical equipment
- Piezoelectric ignition
- Automatic temperature and water flow control when the water pressure in the water supply system changes (for models with WR index)
- Thermocouple for flame control
- Temperature limiter to protect the heat exchanger from overheating
- Draught control device with automatic shutdown of the column
- Atmospheric gas burner made of stainless steel with the possibility of switching to LPG operation
- Tin-free copper heat exchanger with a service life of 15 years
