Conventional boiler is designed to operate with dry exhaust gases. The lowest temperature of the water running to the boiler is limited to the value of 60°C. The exhaust gases temperature is usually in the range of 120 to 180°C. As connected to the heating system, the boiler must be fitted with a device ensuring a sufficiently high temperature of the water running to the boiler (return water) to prevent condensation …
