Until recently Bosch gas heaters were represented by models with traction, open combustion chamber. The new Bosch Therm models with the index S use a closed chamber. Heaters of this type can be used when connecting to a regular chimney or installing a conventional chimney are not possible, and the air has to be “pumped” forcibly

Wall mounted gas instantaneous flow heater with closed combustion chamber Bosch Therm 4000 S
The range consists of three models, this model is recommended for home use. The more powerful Bosch Therm 6000 S and 8000 S condensing heaters, capable of cascade operation and remote control, are suitable for commercial use – operation in large public buildings and facilities
Hot water performance of Bosch Therm 4000 S – 4 to 13 l/min at At = 25°C The nominal heat output can be adjusted within the range of 7.0-22.6 kW. The heater is equipped with a stainless steel atmospheric burner and a forced extraction fan. The electric and electronic components of the system are powered via a 220 V mains supply. The air supply and combustion products can be carried out through a single coaxial pipe of diameter 60/100 or 80/110 mm.
Electronic modulation of the boiler output follows the water temperature and water flow: On the front panel, apart from the main switch, there is a single regulator which can be used to set the desired temperature. No other manipulation required, output temperature value is electronically controlled with an accuracy of 1 °C throughout the entire range of water flow, temperature and supply pressure. Reset and burner status buttons with integrated LED’s are also on the control panel. The first restarts the system in case of failure, after troubleshooting, the second is needed to set the minimum and maximum gas flow rate at given temperature limits by default – 35 and 60 ° C . Minimal switch-on pressure for hot water 0.3 bar and 13/30 mbar for natural gas liquefied gas.
PRICE: 27 000 Dollars.
