3900 3300 2700 2100 1500 900 300 0 Water Quality and Scale A complete water analysis and an understanding of system requirements are needed to protect the tankless water heaters and water heating systems from scale. Water analysis shows whether water is hard or soft. Hard water, unless treated, will cause scaling or liming of the heat exchanger. The rate of scaling increases with temperature and usage because calcium carbonate and other scaling compounds lose solubility (fall out of solut

Pump Sizing for Circulation 1. Use the chart below or one appropriate for your conditions to determine the heat loss in the length of the hot water supply and return piping. For example, 100 ft of 1-1/2 in bare copper tubing results in a heat loss of 5300 Btu/h. Approximate Heat Loss from Piping at 140 ºF Inlet, 70 ºF Ambient * Nominal Size, in. Bare Copper Tubing, 1/2 in. Glass Fiber Insulated Btu/h-ft Copper Tubing, Btu/h-ft 3/4 30 17.7 1 38 20.3 1-1/4 45 23.4 1-1/2 53 25.4 2 66 29

Tank Water Heaters in a Circulation Loop The following applies when using a tank water heater (gas or electric) to provide heat for a circulation loop. Drawing WH-1-RGE is an example. The heat output of the tank must be equal to or greater than the calculated circulation loop heat loss. (Reference page 6, Step 1 on calculating heat loss). Electric Tank Water Heater Since the input and output are the same for an electric tank water heater, this can be expressed as: Electric Tank Input (

Pump Sizing for Storage Tank Application The following applies when using tankless water heaters to recover a storage tank. Drawing WH-1-B is an example. Tankless water heaters have a pressure loss which must be considered in the system design. Reference the pressure loss curve for the heater model being used to determine the pump size for the desired recovery rate. For recommended pump sizes use the table below. Additional pressure losses in plumbing between the
