Heating question: valve replacement and inhibitor
Apologies for yet another post about a central heating problem.
My house's mid-point valve (an ACL 779H340-30L0) hasn't been switching properly for a while. I've disassembled the actuator, and there's extensive arcing damage to the microswitches, PCB and actuator casing, so I think it's time for a new one. It seems that spare actuators for the ACL 779H340-30L0 are no longer available, so I've ordered one of these, which will require a partial drain down of the system: http://www.heatingcontrolsonline.co....lve-p-256.html I have a couple of questions: - There's nothing in the loft to indicate which (if any) inhibitor is currently in the system. Would something like Sentinel X100 be compatible with whatever is already in there when refilling? - Does this sound like a plan? Does anyone know of a source of new actuators for the ACL 779H340-30L0 so that I don't have to drain down the system? Thanks |
