Consumer Information The on-demand water heaters must be installed according to all local and state codes or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.
In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores.
Closed System/Thermal Expansion CAUTION - PROPERTY DAMAGE HAZARD As water is heated, it expands (thermal expan- sion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pres- sure due to thermal expansion.
Temperature and Pressure Relief Valve For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening on the on-demand storage tank.
8 W a ter Quality and Scale A complete water analysis and an unde rstandi ng of system requirements are needed to protect the on-demand 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.
9 Pump Sizing for Circulation 1. Use the chart below or one appropriate for your con ditions 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.
10 T ank W a ter 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 H-1-RP is an example. The heat output of the tank must be equal to or greater t han the calculated circulation loop heat loss.
The following applies when using on-demand water heaters to recover a storage tank. Drawing H-1-TC is an example. On-Demand 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.
