Scale of scale

Working in an office block today; "our water heater doesn't work, could you have a look".



One of those instant 'make a cup of tea' things that delivers boiling water. Heatrae Sadia Supreme 140 - holds 2.5 litres of water.

that power & water were going in, noticed a customer helpline number inside the cover.



Very helpful. Explained the situation to the guy on the phone. "Its scaled up" he said. Told me to take the top off the tank & remove the scale.



Never seen anything like it before, sheets of the stuff coming off.

shows the amount of scale removed, not including the 60-70mm covering the element in the bottom. Apart from the manual removal, I used 3 sachets of descaler to get it clear.



Didn't realise until now they are around £570! Worth the repair cost.

Wouldn't do much for that level of scale but I have had good results in kettles boiling Jif lemon juice - which is cheaper in bottles than in squeezy lemons, and a lot cheaper than descaler sachets.

Another skill you've learnt of financial benefit to you. Thanks for sharing. Water not so hard round here!

You might find it worth investing in a 2kg tub of Fernox DS-3 Its far better than the supermarket descalers, and makes up to 100 gallons of the stuff for about £15 - £18 a tub.

just about anything acidic works. Boiled rhubarb leaves being my mothers old standby..

Depending on what the thing is mae of, a gallon of brick acid often works wonders. ;-)

We have two of those at work and they regularly need cleaning/repair. It ususally seems to mean some bit being taken away. AFAIK this is by heatrae themselves or some approved repairer.
