Domestic Hot Water Service Systems - Design Procedure

Design procedure for domestic hot water service systems.The design of a hot water service system may follow the procedure Determine the demand of hot water from the consumers - quantity and temperature.Select the type,capacity and heating surface of the calorifier - or heat exchanger.Select the boiler.Design the pipe scheme and the size Domestic Hot Water Supply - an overview ScienceDirectSince 1987 the thermal performance of different small solar heating systems for domestic hot water supply have been measured by means of side-by-side experiments at the laboratory,(Furbo et al.,1987,Furbo,1989).One of the tested systems have as the heat storage a hot water tank with a built-in heat exchanger spiral at the bottom of the tank.Domestic water-supply - exampleIn this section I show how to calculate the flow-rate in a real domestic water-supply system by using a couple of design tools that link flow-rate to the available head - the pressure that makes the water move.The worked example starts here .If all you need is the graph that links flow rate to the rate-of-pressure-drop for standard pipe sizes,it's here .
