Fitting magna clean on flow

[marsaday]

I understand these cleaners need to be fitted on the return. Does it matter if my magna clean is on the flow ?

I have just noticed this afternoon where it is positioned. the boiler was moved a month ago you see.

Should it be changed urgently or is it not that big a deal

Dont think it makes that bigger deal. Fitting instructions say preferably on the return just before boiler.

it goes on the return to reduce the muck going into the boiler, it aint working if its on the flow then is it

2 opinions here. i know the return is the best place, but i am in the position of it being done incorrectly.

I have just added 3 new rads to my system this weekend (attic conversion). i still have to fit the rads when i get the walls built etc. I had isolator valves fitted for this run of pipe work so i can still run my CH without draining down. When the work is done on the ch (poss, late jan), should i do a system clean and drain down. if so this will be the time for me to change over the magnaclean.

Final point. i have 3 spiro traps to fit on some houses i rent out. i intend doing this in the spring. Do you think it will be better for me to use a spiro trap over the magnaclean. i think i will go for it as it will be much easier to fit. what do others think.

manufacturers instructions are what you want to follow if you want to get the best performance and you obviously know that, so asking us on here to say its ok to leave fitted in a position not reccommended seems a bit daft to me. As for which kit is better, they all do the same thing and if you already own some spiros use them or if you prefer magnacleans use them,its your choice ultimatey.

An extract from Adey site installations :MagnaClean Professional is suitable for all central heating systems and can be fitted anywhere on the main circuit. However, in order to achieve the best protection for the boiler, it is recommended that MagnaClean Professional is fitted after the last radiator before the boiler. In determining a suitable location for installation, it is important to ensure you allow adequate access for servicing.

Check their site and make up your own mind.

didnt I say that?

I wasn't listening - what did you say?

spiro will fit loads better on the return pipe, just under the boiler. plus lots of people have said spiros are better, so i will try it. never had a problem with the magnaclean though in 2 1/2 yrs.
