Hot water supply for residential use
Thread Content
Hello everyone, the domestic hot water in a certain residential complex needs to be supplied centrally. What I’m planning now is to use the same water tank as that for heating water – is this a reasonable approach? Does a domestic hot water system also require a separate hot water tank? Is one needed for each building? Could anyone help me correct this? Thank you!
Potable water and heating water should be separated. Heating water can be reused, while domestic water is subject to strict regulatory standards. It is also necessary to separate them for the health of the residents. For domestic hot water systems, a separate hot water tank is required; it is not necessary to have one in every building. Through calculations, if the pressure is sufficient, the number of tanks can be reduced by increasing their capacity instead.

First of all, domestic water and heating water must be separated. Secondly, whether it is a domestic hot water system or a heating system, it is possible to omit a hot water tank. The system is designed as a closed-loop system, with the system’s water supply pressure being adjusted by controlling the make-up water valve. If you have any questions, feel free to discuss them further!
