Hi
i have a central heating system with the cylinder in the airing cupboard
i have 10 radiators all with manual valves
i want to change to TRV so that i can regulate temperature in te bed rooms which sometimes becomes hot
i am employing a plumber/ heating engineer to do the job
reading through the internet i feel to descale the system and put in inhibitor as water in the system is dark
i have bought some Scalemaster SM4 to do this
my engineer tells me that it is difficult to get these types of substances out once put it in unless powerflush and advises me that not to bother with it
However, salesman in the shop which sells these substances tells me unless you get rid of these scales and put in an inhibitor the TRV may not work properly
i am confused as to which one to follow
Many thanks in advance for advise
