Water heaters with closed combustion chamber

Closed (turbocharged)

— the name of this type of combustion chamber is because they are isolated from the room in which the water heater is installed: the air necessary for burning gas is supplied from the outside, using a special fan. Due to this, water heaters with closed chambers do not consume oxygen from the room, and they can be installed in any room, regardless of their volume and ventilation conditions. At the same time, such models have restrictions on the maximum length of the chimney, and their cost is usually higher than options with open chambers.
