Hot Water elements
Our two year old hot water element has just ‘gone’! According to our electrician there are hundreds of elements going ‘on the blink’ due to the addition of Chlorine! Time to send the bill to the council!!!

I hear large parts of west Chch no longer get it added to their water.
– Pim Zegerman from Bromley, 15.9.18

Feel for you Brian, yes your electrician is on the ball concerning water heaters, water heater elements, and pipe entrance/exit jointing seals, and this wonderful additive called Chlorine, that causes failure to these items for a number of reasons. For our lustrous elected councillors and the council employees, this is not there concern as they are meeting the United Nations water quality standard and our Governments intended agenda to have all fresh water supplies in NZ Chlorinated, whether they require it or not. Sadly for us CHCH rate payers the Chlorine is here to stay.
– Neil Borlase from Opawa – Saint Martins, 16.9.18

We replace our element about every 2 years but never the cylinder, Yet!
Agree with chlorine being removed from our water 💦 who has ever been sick from our aquifer water? If I want chemicals I’d buy coke. Lol
– Laura & Alex Ilkiw from Cashmere, 16.9.18

Wondering if the trail leads back to the chemical companies who stand to do very well out of poisoning us all.
– Colleen Johns from Mount Pleasant – Redcliffs, 16.9.18

Totally agree Colleen!

Mine also idiots at council

Our 5 year old Peter Cocks cylinder also had an element corrode recently. Rheem, who own Peter Cocks refused to get involved even though the New Zealand Building Code states that cylinders must last no less than 15 years. I contacted the Council, there response is below:
“We are not reimbursing residents any cost.
There can be a number of reasons why a cylinder may fail. Water cylinder failure is not a new thing in Christchurch. We’re aware of it as a long-standing issue over several years that has affected certain parts of the city more than others.
Christchurch’s water supply continues to meet the requirements of the New Zealand Drinking Water Standard, with chlorine levels similar to other parts of the country. We encourage people to make sure they check with suppliers that any system is fit for purpose and installed by a suitably qualified person.”
Pretty disappointing from both Rheem and the Council. I’m lumped with a $442 bill (around the same as my insurance excess).
– Andy McLeod from Mount Pleasant – Redcliffs, 16.9.18

Yes I agree my hot water cylinder leaked, my Sisters and 1 of my workmates CCC doesn’t want to know neither does the Insurance Compancies – wear and tear !!!!!
– Michelle Gay from Woolston, 17.9.18

mine also and im sure redpaths electrical are loving the sales.seems to be more a common problem on the port hills
– Andrew Banks from Cashmere, 19.9.18

Ours too. 2 years old. Same problem. $300 later.
– Carren McDonald from Mount Pleasant – Redcliffs, 20.9.18

Wondering if the hills reservoirs serve just the hills, if homes on the flat get a direct water network supply? Because this may explain Andrew’s point, if leached lime from concrete reservoirs wrecks hills water heating appliances in quite short time, unless they are copper inside.

Hot water cylinders and chlorine
Just to throw a curve ball at you all, If it only took several months to wreck your cylinder as there is no guarantees it will come out at 12mths isn’t it going to happen AGAIN with the chlorine …mm mm….. We have got a full in-line filter which costs about 1500 installed by a plumber, thats at least the price of a new Cylinder replacement and with new filters every 12mths we wont have burn out from chlorine, another note What is it doing to everything else dishwashers, washing machines, not to mention your good gut bacteria, the mind boggles..

titanium element much better

We were a rebuild (Brickworks Lane) and had a brand new cylinder. We went through three elements (One every three months). They finally replaced it with a titanium element on Christmas Eve! This seems to have fixed the problem.

stainless steel care needed, hard water

This is due to the stainless steel, not the water. This is the point of stainless steel, it is very resistant to corrosion but if it touches virtually any other metal, other than stainless steel (the same type of stainless steel mind you) then it will cause the other metal to corrode faster. This is when they are in physical contact and wet (the water acts as an electrolyte).

This is why you should never have copper, galvanised steel or mild steel in contact with stainless steel when they can get wet i.e. outdoors or in plumbing systems. If they are needed to be together, the two different metals need to be separated by an insulator such as plastic or rubber.

Many hot water cylinder elements are made with an Inconel sheath (a nickel alloy) which would be ok for a copper cylinder. They should really have a stainless steel sheath as the Inconel sheath is good for high temperatures but this not necessary for a hot water cylinder.

The Centaurus/Huntsbury water supply is definitely different to other parts of ChCh. We get lime scale in our kettle, which I have never had in any other suburbs.

sacrificial anode preserves solar HWC element

We’re down Bowenvale and had our new hot water cylinder replaced a couple of years ago. At the second failure we installed a sacrificial anode and haven’t had a problem since. Probably something that needs to be done as a matter of course. I understand the old copper cylinders are OK but the stainless steel ones just corrode.

We did have gas and decided to go solar. For this we needed to put in a cylinder and that’s when the problems started. First we had to replace the element after about year and then the whole cylinder and the element after another 6 months or so. This is when the sacrificial anode was added and that seems to be working.

Huntsbury high dissolved solids

We had our water (near The Brickworks) tested at 350ppm total dissolved solids, which is 10 times what it is at Kaiapoi.

We had 2 in-line pressure droppers fail because they jammed on deposits from the water.

teflon-coated element fix

We had problems with the heating element burning out every two-three years. The installation of a teflon coated element seemed to fix it.
