Just a quickie.
I have an s plan system, the 2 port for the heating circuits is not passing,
when i have demand for hot water only, all upstairs rads heat up.
The auto bypass is located incorrectly i.e tee's off before the valve (ok)
but tee's back into the cyl return not primary return.(not ok)
Does anyone think this may cause the flow to channel trough to the heating circuit? can't tell how anything is connected to the primary return as under tiles then ply!!
Suppose i could prove if cycling the wrong way by first turning the heating on and checking which is the flow pipe, then allow to cool, turn on hot water and see if other pipe (return) heats up first??
Any other ideas anyone?? would be very greatful.
