Fernox vs kamco power flush units

[lame plumber]

if you can use a hot flush it works better, if no boiler an immersion can be used on some makes, Norstom for one but bleedin expensive

The kamco is up to 50deg I think, both do a corse with the package. The 90 is the big one right? It's not that I wanna do a rush job but speeding up the process always helps

It says in the MI's upto 75degrees mate, only because I've looked online.

I wonder how well these immersion heaters work.
I mean the most they can put out is 3kw max. I just can't envisage them heating a system up to any meaninful temps for flushing.....am i wrong ???

Just use the boiler??? At a guess I am new to flushing and the heaters do look a bit of a gimmick but if u keep the boiler connected and just remove the pump use that????

All well and good if boilers working.
But some are DOA

Are the kamco unit with the dual magnets can u use one for a heater and 1 for magnet or is that just ott

The kamco acid cleaner will wreck alloy heat exchanger apparently where the fernox don't so they say

You just do not use FX2 acid on aluminium heat exchangers, it's in the book.

You can get a free booklet off of Kamco which lists most make/models of boilers and the metals they contain. I do however also contact the manufacturer of the boiler to double check.

thats a good shout, I stopped off at the merchants I use yesterday and quizzed them in there he recommended the Anton flow clean, bit cheaper also.
was asking about chemicals and I asked about fx2 and how strong it is and ally in boilers and he seemed to think it's all right!!!!! "Won't have a problem at all"

but it then I was talking to a good mate who is gas safe and he NEVER flushes a boiler he always by passes it so he can't be blamed for anything going wrong with it over the next couple months

Kamco have a disclaimer on their site that you can print off. I have a load printed off to get signed before work commences.
