2. Boiler circulator(s) must be rated for open loop applications. Do not use cast-iron circulators. 3. Boiler circulator(s) operate continuously. 4. The minimum pipe size for connecting to a water storage tank is 1 ½. 5. The minimum pipe size for connecting the boiler is 1 ½ for the Mod Con 300 VWH and 2 for the 500 and 850 models. 6.

A variant of the helical coil boilers is the Spiral Plate Heat Exchanger shown in Figure 2. Here, the spiral surfaces are separated by raised bosses and sealed with two end plates. The hot fluid enters at the center of the unit and flows towards the periphery in a spiral path.

Consider another example, selection of an air heating coil, summarized in Table 2. A 20˚F (11˚C) delta-T on the water side is often used to size heating coils. High-performance systems require coil selection at a much higher delta-T, in the 80˚F (45˚C) range. A heating coil is required in an AHU to heat 10,000 cfm (4719 lps) of air from 35
