Welcome to Just Answer!Because of the way air can be trapped in the system if you reverse the hot and cold connections to the panel it can stop the water flow... the panels can then overheat.Give me some details on what problems you are experiencing, we can go from there without any time limit.Phil
Thank you for your answer.
With the hot water being taken from the bottom of the unit and the cold going into the top – I am concerned as to whether this would make the unit less efficient and more reliant upon the gas boost ie would this increase my gas bill by any appreciable amount. When I turn the boost off, there seems to be not much hot water even in summer.
Does this reduction of 30 - 50% in efficiency directly relate to a similar percentage increase in gas usage
We engaged a plumber in March this year to check on the HWS.
He replaced a faulty pump and also reported that the hot and cold pipes were incorrectly installed when the initial installation of the panels was carried out.( that was when the house was built in late 2007)
The pipework was repiped to ensure correct direction of flow.
What I am attempting to establish is what effect the faulty workmanship would have had on the unit and the gas bill.
Thanks for the info Phil and the promptness of your replies.
