Fernox DS40 - Advice
As in my previous post I have a noisy Glowworm Economy Plus 60 F in an open vent system with S plan controls. A look at the previous threads on this subject has convinced me that Frenox DS40 is the way to go; I was looking far a little advice on its use.
Is the only option to add to the expansion tank, once the system is drained down?
Should I assume a day to drain/clear the system after the 7 day run?
Any advice gratefully received.
