if you pull water from a service boiler to test it, if scale is forming your test will always show the water as non-scaling afterwards.
Not sure, this is clear.
Let’s say, I steam, switch the boiler off, the machine off and draw some water to test. The usual 20 ml each and standardise for 5 ml.
At room temperature, the kit shows 40.28 mg/l alkalinity and 11.2 mg/l of hardness.
This is where your excel is valuable. I put this in your excel, I know already the maximum hardness allowed in cell B24 is already higher than the value shown by the drop kit. I don’t have to adjust alkalinity and hardness in cells B16 and B17 to see how many mg/l of scale has already formed.
Rob1 how much scale has formed without knowing how much water you’ve lost when steaming.
Based on the above observation of the data, for the given steaming. I don’t need to know how much is lost in steaming, do I ?
I understand some water lost in steaming as it leaves the minerals as deposit. In my Evo, for example, I steam 350g of milk once a day. After steaming for about 35s, the pump has never kicked in, during the last 6 months, unless I open the hot water tap.
I remember Dave recently posting in another thread, the water lost in steaming is not significant, perhaps, 30 ml is lost in per steaming.
So, for scale to become an issue, we need to steam a few times a day, leave the water to sit in the boiler, not draw something out regularly and do not flush out the water and replace once in 5-6 weeks.
The bottom line therefore is not feeding the machine with the water, which will scale. Always draw a cup or more water out weekly and do a full flush once in 6-8 weeks — in machines like Evo, it will be a half flush. Of course, descale periodically, may be once in a year, depending on the frequency of use.
Cuprajake That’s costs a fortune! 😀
I am asking all this because, many might not feel comfortable to ask. Hopefully, posts / threads like these will be seen as an enrichment of knowledge, help folks understand the importance of feeding good water, take simple steps to minimise scaling; assuming these discussions are not seen as argumentative 😊
