See Figure 5 – Piping diagram indirect tank with boilers having an internal pump, three-way valve, and dedicated boiler water outlet for indirect tank. With
boiler working in the central heating mode, the three-way valve sends hot boiler water to CH supply. In DHW mode, the three-way valve diverts all boiler
water to the indirect tank supply.
Piping diagrams shown in Figures 4 and 5, zone pump configuration for the central heating is shown. They can also have a CH system pump and zone
valve configuration, with one CH system pump on the supply header. The Zone valve opens or shuts off the boiler water flow for each of the central heating
zones.
