AQUA PLUS indirect-fired water heaters — Product Manual

Troubleshooting (continued)

Insufficient hot water (continued)

4Check boiler operating temperatures.

If possible, increase the boiler operating temperature to 180°F or 200°F.

Maintain a minimal temperature in the boiler during non-heating seasons.

A boiler typically has a higher standby loss than the indirect water heater.

After a long standby period, the colder boiler may absorb the stored energy within the water heater during the initial call for heat.

5Check location of flow control devices.

Lab tests have shown that during long standby periods the boiler piping can act as a thermal siphon and draw stored heat from the domestic water.

Locate flow control devices (zone valve, spring check valves...) or heat trap loops in the boiler piping close to the water heater.

Insulate all boiler piping to and from the water heater.

6Check for air in the system; check water heater air vent.

An air-bound water heater or boiler will not circulate system water properly, resulting in a lack of heat transfer.

7Clean the boiler water system.

A dirty boiler system can cause deposits to form on the water heater coil. This insulates the coil, reducing the heat transfer.

Clean the boiler system per the boiler manufacturer’s instructions.

Install a strainer in the boiler piping on older installations or for systems likely to carry sediment.
