2.5 CONNECTION OF INDIRECT HEATER TO HOT WATER SYSTEM
It is recommended to install stop valves on the heating water inlet and outlet (for possible
dismantling of the heater).
The valves have to be as close to the heater as possible to avoid
higher thermal losses. (Figure 6, Figure 7, Figure 9 and Figure 10).
