I have been looking at inhibitor to put in my CH system after I fit my
thermostatic valves. I notice that some say do not put in systems that are
made of aluminum but how do I know what my boiler is made of? I have an
Ideal classic RS50 (no longer made of course) and the Ideal website isn't!
it doesn't mention the boiler.
Also, if anyone can advise. I watched a few You Tube films of people
installing TRV's and most use 'paste' or 'compound' around the edge of the
threads and some then combine that with PTFE tape. But in my DIY book it
says you should never combine 'compound' and PTFE. What's the best practice
and what is the correct thing to ask for in the DIY shop i.e. the correct
name for 'paste' or 'compound'.
Further question. I live in a heavy lime scale area, I bought some system
cleaner to swish around before starting this project, it is supposed to
clear sludge and lime scale (made by Wickes). But a colleague just told me
he was advised by his local plumbers merchant not to attempt to use this
stuff in these areas because they cause more trouble than they fix. He
recommended just flushing out the system, fill it up and flush again because
these solution can dislodge lumps of lime scale that will later work free
and cause untold damage to the system after the job has been done - any
comments on that?
