Joined a firm who does solar thermal & PV, so a newbie at the green stuff
As above it was an oppen vented cylinder + solar therm + boiler. The experienced Installer who Im working under wanted me to fit the TMV on the hot outlet of the cylinder before the open vent pipe. I was confused at first thinkig it was some sort of test, I pointed out that the TMV needs to be on the other side of the open vent otherwise it becomes a sealed system.
He went a bit pale then, Am I right, I think I am. I done a post before about system working pressure and the charge on the expansion vessel being different. Will pay for the BPEC course myself if I have to as I dont mind working under someone but Im getting conflicting info all the time
