A relatively inexpensive flow boiler, positioned by the manufacturer as a middle-class model. Due to its sufficiently high performance, the device is able to serve an intensive flow of consumers in shower dormitories or factory change houses. So, with a significant heat exchanger power of 17.4 kW, the device has a compact size and low weight of 11 kg, which simplifies installation on a wall in a vertical position.
The open combustion chamber is connected to the chimney with a pipe with a diameter of 112 mm, and the ignition of the fuel is carried out by a battery-powered spark gap. For safe operation, the Bosch GWH 10-2COB instantaneous water heater has overheat protection and gas control functions. The latter is responsible for automatically cutting off the supply of natural gas in cases of sudden extinguishing of the flame. The maximum operating temperature is 60 °C and is maintained within the required limits by a built-in temperature controller of a standard design.

Bought and installed the heater six months ago. Installed the batteries and forgot what a pilot light is, no unnecessary gas consumption. I consider it an optimal solution. Batteries are not that big of a problem (they work great for six months), so I see no point in overpaying for ignition from a hydroturbine. Regarding consumption: a family of 3 people, we use it for showering, baths, and washing hands (we wash dishes in a dishwasher). It's more than sufficient for these purposes!!!! When you open the kitchen faucet while using the shower in the bathroom, you feel a slight drop in temperature. But if you open the faucet gradually instead of abruptly, the [censored] in temperature won't even be noticeable. This is the result of a burner with modulation (which cheap heaters don't have). It was quickly and easily installed in place of the old, Soviet heater. Smaller in size. When connecting, I installed a gas filter and a magnetic "scale blocker" for water. This will prolong the life of the heater. I PRINCIPALLY ordered installation at an authorized BOSCH service center (even though I know my way around and have disassembled and reassembled the old heater about 20 times to its core). Firstly, they have the permits for installing gas appliances and will be responsible in case of any issues. Secondly, this keeps the manufacturer's warranty valid. Thirdly, if after the guarantee period (within a month) you perform a scheduled maintenance on the heater with an authorized service center, you get a second year of warranty. I recommend it to those who are ready not to take risks with cheaper tech. At my parents' place, they installed an "Amina" type. Initially, everything was fine. Now it "explodes upon ignition", and the burner has no modulation. convenient, beautiful, burner with modulation. Performs the assigned task didn't notice use Bosch Therm 4000 O WR 13-2 B month or more i recommend it should buy |
