Brass thermostatic mixing valves for heating systems

In the process of burning, among others also water releases from burning fuels in the form of steam. When the flue gas temperature is high enough, the steam comes out through a chimney together with flue gas. However, if the flue gas cools down at a certain spot, condensation occurs. Condensate is formed, 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.

Corrosion will not occur if the heat transfer surfaces are warm enough because condensation will not occur above certain temperatures. The heat transfer surfaces will be warmer and their service life longer. TSV1 and TSV2 thermostatic mixing valves mix cold return water with hot water from the boiler outlet. Thus the whole heat exchanger (heat transfer surfaces) is kept warmer, at temperatures that will not allow condensation to occur and so clogging and corrosion will be prevented.
