Bosch WSTB 300C Indirect heating boiler
Bosch WSTB 300 indirect heating boiler is designed for use in country houses and cottages in combination with floor and wall heating boilers. The model was developed taking into account the specifics of Russian operating conditions: hard water and pressure drops in the system.
The principle of operation of an indirect heating boiler
The hot coolant flows from the heating boiler to the coil heat exchanger located inside the boiler. Thanks to the large area of the heat exchanger and its special shape, the water stored in the tank is heated even faster and more efficiently. Connecting the recirculation line allows the user to receive hot water at the moment the tap is opened.
The equipment has an internal glass-ceramic coating, which provides tank protection against corrosion and absolute hygiene of hot water preparation. The inspection hatch is located on the front side of the water heater.
Thermal insulation is made of safe materials and allows you to minimize the heat loss of water in standby mode.
