For preventing condensation

In the process of burning, among others also water releases from burning fuels in the form of steam. If the flue gas temperature is high enough, the steam exits through a chimney together with flue gas. However, if the flue gas cools down at a certain spot, condensation occurs. Condensate forms, containing further combustion products that can be very aggressive, esp. when burning wood or solid fuels, and can cause corrosion very quickly as well as clog heat transfer surfaces.

TSV1 and TSV2 thermostatic mixing valves mix cold return water with hot water from the boiler outlet. This way the whole heat exchanger (heat transfer surfaces) is kept warmer, at temperatures that will not allow condensation to occur and so clogging and quick corrosion will be prevented. Clogged heat transfer surfaces deteriorate boiler efficiency substantially and increase the risk of scale formation.

Quick corrosion and clogging will not occur if the heat transfer surfaces are warm enough as condensation will not occur above certain temperatures. The heat transfer surfaces will be warmer, making their service life longer and the boiler efficiency higher. These valves are fitted with thermostatic valves by a renowned French manufacturer.
