- Abstract:
- Standard for Design of Building Water Supply and Drainage (GB 50015-2019) stipulates that water heater with heat storage regulation volume shall be used when the local hot water supply equipment supplies two or more plumbing fixture for simultaneous use. The problems of gas instantaneous water heater in domestic hot water supply were analyzed by comparing the relationship between the parameters of the gas instantaneous water heater and the thermal load of the plumbing fixture. The gas instantaneous water heater with hot water producing capacity of 8-16 L/min that is common in the market could only supply to one plumbing fixture. It is suggested that the dwellings with a kitchen and a bathroom, a kitchen and two bathrooms should equip the water heater with heat storage regulation volume.
