Hi every one,

Many thanks

not really, the older ones were pretty crap in the insulation area unless you wrapped it in insul blanket,make sure you keep the old cyclinder as theres a fortune in copper there, the plumbers usually say "yea we take the rubbish away for ya'" yea all the way to the bank.

Thanks, just trying to figure out what to do, as it looks like the elements are going/onlast legs, we have a twin element one is there any advantage to this other than it heats up quicker ! $160+gst each element new cylinder $1100 or so

And don't especially care if you want to keep it either. An old cylinder does have thicker copper, but as in 30 years old +. Newer ones have their own insulation these day. A newer cylinder, depends on the US copper price, can get $30, maybe $70. Scrap dealers give you more if you strip it, and remove the inner copper part. That's a mission in the new ones. Not exactly a laugh all the way to the bank.

they have stayed pretty much the same throughout the 90s to now. And the only advantage to having 2 elements is that it heats quicker and therefore more efficient as it does not let the water get too cold in the cylinder. Depends on how many people live in your house is to which one I would get.

You are better off going with an instantaneous water heater like the Rinnai Infinity. They are available in models to run on natural gas or LPG. You only use energy to heat the water you actually need and want at that time, not waste energy to keep a tank full of water hot 24/7. Less maintenance (almost zero) as well.

OHHHBOY. !Here we go again . All Cylinders have to comply with a certain standard - and that meansthey allhave a minimal heat loss .( usually a HWC looses between 1-2 kwh a day on average ( that if you dont use any hot water at all ) . in a nutshell you tend to onlyreplace the same amount of water that you actually use . If you want extra insulation well there is nothing wrong with wrapping a few extra layers of insulation around it ( and around your water pipes ! (because thats where most of your heat disappears .) 2 elements in a HWCare good if there are 8 of you in the house and you only have a 180L HWC- basically they heat the water up a lot faster - thats about it . as far as there usefulness goes . How good or how bad a HWC isdepends on the $$$ you spend on it . Cheap Cylinders are made from mild steel with a Enamel / glass liner in them ( 1 hairline crack and they start to rust from the inside out . better ones are made from Stainless steel( we are talking about mains pressure HWC here ) and a cheap one is made from 0.9mm thick stainless steel ( or less ) then you get 1.5/1.6/1.8 and 2mm thick steel . The thicker the stainless steel is , the longer it takes rust to nibble a hole though itand the longer they last . So when you buy a HWC the question is : How soon do you want to replace it again !The Price difference can be a $1,000for the same size HWC -between a cheap one and a good one .

Hey Wunderbar, would be good if there was a section on here where we could post permanent answers for these FAQs eh! I also get tired of answering the same questions time and time again.

Yep,.I have done something similar on my website - to answera lot of those questions which tends to help a bit . Have the problem is, where to look for help / and answers to those FAQ - as there are not many places on the web - where you can find answers to them unfortunately . There are plenty of places that sell you Cylinders - but trying to get some help , or advise - there is virtually nothing out there .
