Descalling boiler

[Simon Meadwell]

Hi
Does everyone descale their boilers all info seems to contradict itself.
Use vinegar dont use vinegar use citric acid dont use etc
Is there a difintive answer?

We use citric acid to do ours, very easy job. Bob.

Ours obviously hadn’t been descaled in a long time or perhaps ever, so having read somewhere that it’s a good idea we set to the job, despite the fact our heating and water were absolutely fine.
Flushed the system several times getting small amounts of scale out each time we did it, the only problem being that now the boiler didn’t work. Holiday approaching we called in a mobile guy to try and recover the Situation, he eventually took the Trauma out and shook loads more limescale out, we think the dislodged deposits blocked up, well who knows what. The bottom line is the boiler never worked again and we had to buy a new one at considerable expense, I wish we hadn’t bothered.

Descale mine once a year use 3lt of white wine vinegar (30p Lt in France) Truma used to recommend white wine vinegar until they started marketing their own descaler.

I get ours from Wilko's in town, although I might well get the next lot via TheBig1's eBay link.

I use citric acid, mainly as it was the main ingredient in trumas own descaler that they used to sell. I don't think they do a specific one anymore and now just advise to use vinegar or citric acid or other specialist one.

I get mine from amazon (amazon link below which those using adblockers like me probably won't be able to see) £8.99 delivered for 2kg

Amazon product ASIN B00UVJ1K72

As with anything it’s always best to ask the manufacturers if in doubt.

I use citric acid, used to use white vinegar The citric acid is easier to flush out of the system less taste and no smell

 

[Mickey1]

I must ask, do you add vinegar/ citric acid to your fresh water tank or is there somewhere else to clean the boiler?

Yes I put 3 Lt vinegar and about 10-15 Lt of water in the tank. Fill the hot tank and flush it through the taps & set the hot water to 60° and leave for a few hours before flushing with clean water.

Ditto, white Vinegar from France. The French use it for cleaning in their homes!

Ordered my citric acid a few days ago ,should arrive today so that’s the top of the to do list on our new to us B544. Thanks for advice on only useing 10-15 gallons, as I would have filled the tank right up, hope my boiler works when mine is done. There is all sorts of rubbish coming out of my taps so it has to be done, thanks again .

If it's that bad you will probably need to do it 2 or 3 times.

@bubble , Lenny said litres not gallons

So im going to use citric acid how much acid per litre of water do you use?

 

[ctc]

Used Puriclean supposed to descale, clean etc. Certainly cleaned the waste water tank and the tea cups,just not at the same time.

I use 500g citric acid per 50 litres of water which is the ratio that Truma used to recommend for their own product which pretty much consisted of citric acid.

Truma AquaStar 1 - Descaler

• AquaStar 1 is very effective in removing limescale from your drinking water system, along with the bacteria present in the limescale
• The powder rids the water completely of the otherwise unpleasant odour and taste
• Thanks to its gentle action on metals and seals, AquaStar 1 is particularly well suited to recreational vehicles
• AquaStar 1 should be used regularly twice a year

Product coverage: 500 g powder (citric acid) for up to 50 litres tank volume

Don't they have a form of chlorine in them if so souldn't be used in the boiler as it's stainless steel.

@clanjones wrote about this and recieved a letter from Truma
““Head office have confirmed the use of citric acid and the ratio they recommend is 1 tablespoon of citric acid to 1 litre of water”.

Not according to the blurb on the pot.

 

[Riverbankannie]

According to the product safety sheet for puriclean tubs they contain a chlorine based bleaching agent, I.e. I think, bleach.
