On direct water circulation systems:

 

Problem

Symptom

Solution

Insufficient insuation

Fittings at the end of panel array and at bottom feed connector and in tank all at similar temperatures but water in tank does not heat up much

Install insulation on all pipes in the solar loop, no matter how warm the climate.

Air In the Loop, no circulation

Fittings at the end of panel array get very hot, but fittings at bottom feed connector don't and water in tank does not heat up

Bleed air out of loop

Check if pump is running (Slight vibration and sound)

Check for kinked lines or other obstructions

Are all valves in the correct position

 

Pump not running, no circulation

Cannot feel a slight vibration when touching the pump, no slight pump sound

Check pump polarity

Check wiring and connections at PV panel and pump

on TD5 check selector switch setting

Pump noisy

Pump makes screeching sound and stops running

Pump noises are due to air in the pump or incorrect orientation of the pump. Make sure pump is installed horizontally and all air is bled out of the system

Bottom Feed Connector “Short Circuit”

Fittings at the end of panel array and at bottom feed connector get very hot but water in tank does not heat up
