22Anti-freeze solutions expand more than water. For example: A 50% by volume glycol solution expands4.8% in volume during a temperature increase from 32 oF to 180oF, while water expands 3% over thesame temperature rise. Allowances must be made for expansion in system design.A 30% mixture of glycol results in a BTU output loss of 15% with a 5% increase in head against thesystem circulator.A 50% glycol mixture results in a BTU output loss of 30% with a 50% increase in head against the systemcirculator.It is highly recommended that you carefully follow glycol manufacturer recommended concentrations,expansion requirements, and maintenance recommendations (pH additive break down, inhibitorreduction, etc.) You must carefully figure the additional friction loss in the system as well as the reductionin heat transfer coefficients.I. ZONING WITH ZONE VALVES1. Connect heater to system as shown in the Piping Details diagrams. Properly size circulators for frictionloss of zone valves and piping for proper operation.2. Connect DHW (domestic hot water) piping to indirect storage water heater as shown.J. ZONING WITH CIRCULATORS1. Connect heater to system as shown in the Piping Details diagrams. Properly size each zone circulatorfor friction loss of each zone for proper operation.2. Install a separate circulator for each zone.3. Connect DHW piping to indirect storage water heater as shown.K. MULTIPLE HEATERS1. All piping shown is reverse return to assure balanced flow through the connected heaters.2. Connect DHW piping to indirect storage water heater as shown.
