[Puddle]

flush through with mains water first

Then I use 'spirit of salts',but do outside or well ventilated area and be very carful with it,cleans like new

puddle what is that chemical ???

 

[shorticus]

it's hydrochloric acid, get it from home and garden type stores...don't forget your chemical gloves though

 

[shorticus]

...oh and goggles )

 

[Puddle]

muriatic acid,sulfuric acid and salt =Hydrochloric acid

I order a box when needed from my parts supplier however a lot of plumbers merchants ect will not stock due to dangers of stocking and handling incorrectly,not worth the risk,however a lot of small hardware stores still stock it but you will have to ask as not kept on display

As shorticus says ,you can get you chemical gloves there too !!

Hydrochloric acid is a great cleaner, downside is that you need to neutralise it before even considering flushing it down the drain or more importantly rinsing the heat exchanger through.

Best chemical by far is DS40, it comes in a box with its own neutraliser powder and has a colour change to let you know when its done. I take our the DHW, boil a kettle and fill a bucket, pour in the powdered DS40, give it a stir and drop the HX in for 20 mins or until the liquid turns from red to green.

You then pour a small amount of neutraliser powder into the bucket and stir, then rinse the DHW and its good to go.

Vokera service manager, Steve Rogers showed me it and all of their service team use it as well as British Gas, except they got DS40 rebranded as an in house product.

Best regards

i usually use Kamco FX2 powerflushing chemical pour it in let it sit and bubble. copious amounts of water to dilute after it stops, repeat as necessary

i have used vinegar and even cheap coke to do this before the coke is quite successful but has to soak over night so not practical this sounds good stuff

 

[shorticus]

I was diving out in the red sea a couple of years ago and by the end of the week my not too cheap knife went quite rusty, one of the deckhands chopped the top off a bottle of coke and dropped it in, 20 minutes later it came out looking like new, I drink my Jack straight now lol

I used to use ds40,sure originally it was in a liquid form years ago,then started selling in powder form ,with pack of neutraliser

It cleans out mildly scaled blocked main heat exchangers ok,you have to warm up but found if fully or badly blocked,not very successful and would take a long time,if it did work
On plate heat exchangers that is badly blocked I find ds40 not very good and there i also the point of cost,can use quite a lot to clean a exchanger up correctly
It will sort out lime scale build up,very well and system slugde however anything else,it finds hard work

imho

 

[Billy Bob Bob]

but worth a shot though puddle,ok on a performa you would just bung a new one as they are not to dear,but on a tat heat line it costs £100 so well worth trying ds 40 first

Had a call today from an elderly couple with a Boulter combi oil boiler circa about 1995 . having serviced it recently I new the heat exchanger was getting blocked . Now they say their hot tap produces about 2 pints then gets cooler and they want me to fix it . Rang local spares place , they rang worcester who said heat exchanger is obsolete . I am wondering wether to try another supplier or descale with acid . Trouble is if I descale the HE the boiler will obviously have to be off for a long time while i am doing it and in this weather it is not good . Any ideas please .
