Indirect Solar system not heating my water.
I have a 300l floor standing indirect solar geyser. It's heated from 2 kwikot panels on the roof by means of a circulation pump.
My problem is that the pump runs, but it would appear there is no circulation of the glycol/water solution as no heat is being transferred into the geyser water.
Any ideas where I can start / what I can check? It's been suggested that there's air trapped in the system. Shall I bleed the glycol/water solution completely and then refill it? How would I go about doing that?
Thanks
