The indirect system prevents furring of the boiler, primary flow and return pipes, and hot water storage cylinder. The system is also employed in soft water districts when heating is combined with hot water supply, to prevent rusting of the cast iron radiators, which causes discolouration of the water to be drawn off.
The supply system is split into several zones supplying a maximum of 12 floors each. This ensures adequate water pressure on all floors without using pressure relief valves.
Indirect System of Hot Water Supply. Hot water system components . 1. Expansion valve. Expansion devices in hot water systems are designed as a safe means for discharging water when system operating parameters are exceeded, i.e. in conditions of excess pressure and/or temperature.

This document discusses different methods of hot water supply systems. It describes electric, gas, solar, and central hot water heating systems. It also explains the differences between direct and indirect central hot water systems.
direct cross connection is a piping system connecting a raw water supply, used for industrial fire fighting, to a municipal water system. • An indirect cross connection is an arrangement whereby unsafe water, or other liquid, may be blown, siphoned or otherwise diverted into a safe water system.
The hot water supply system allows to recover thermal energy extracted from thermal zones which undergo space cooling to integrate hot water production covering only, if necessary, the remaining quota of the heating load.
