Description
The anti-condensation thermostatic valve regulates the temperature of the water returning to the heat generator to the set value (50 °C or 60 °C).
This keeps the heat generator at a high temperature and prevents acid condensation of the water vapour contained in the flue gases.
Acid condensation corrodes the metal walls of the heat generator and generates dangerous incrustations that reduce thermal efficiency and are flammable.
The anti-condensate valve therefore extends the life of the heat generator.
The valve is calibrated at the factory to a temperature of 50 (60) °C and is suitable for solid fuel heat generators.
Up to 50 (60) °C, the valve only keeps the recirculation by-pass of the circuit open, causing the water in the fireplace or heating stove to heat up quickly and thus preventing the formation of corrosive condensate on the flue side. Between 50 (60) °C and 55 (65) °C the valve progressively opens the user circuit and closes the by-pass, gradually bringing the water in the system up to temperature.
Above 55 (65) °C the by-pass is completely closed and the valve diverts all the hot fluid to the user to keep the return to the fireplace stove always hot.
