2 Certifications .................................................................................. 3 Water Quality and Scale ................................................................ 4 Pump Sizing for Circulation ..............................
3 Approvals Certified to applicable U.S. standards for appliances using gas or other petroleum fuel. Certified to applicable Canadian standards for appliances using gas or other petroleum fuel. Certified by the Uniform Plumbing Code (UPC) Certified by National Sanitation Foundation (NSF), www.
4 W ater Quality and Scale A complete water analysis and an unde rstanding of system requirements are needed to prote ct 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.
5 Pump Sizing for Circulation 1. Use the chart below or one appropriate for your co nditions 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.
6 T ank W ater 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.
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 m odel being used to determine the pump size for the desired recovery rate.
