An 8 L Heat exchanger is a chimney-mounted water heating component designed to make more efficient use of the heat generated by a wood-burning sauna stove. The unit is installed on a 115 mm diameter chimney and transfers a portion of the chimney's heat to water.
This solution is suitable for saunas that use a remote or separately installed water tank. The heat exchanger is integrated into a water circulation system and helps produce hot water by utilizing the natural heat generated during sauna stove operation.
The body is manufactured from 0.8 mm thick AISI 430 stainless steel, making it suitable for high-temperature sauna conditions. Its compact design allows for easy integration into compatible chimney systems.
