6.1. Connecting

Four-way mixing valve is essential for any installation. It’s role is to mix hot water (contribution

water) with the one returning from the system. Water mixing is necessary as to avoid „cold return

of the water” and to keep the same temperature of the boiler. What follows the temperature of he-

ating system’s feeding can be lowered to the temperature of satisfactionary warmth in the house.

Mixing valves should be used both in gravity system and with extorted ow (pump).
