Copper Lining of Hot Water Storage Tank

Wouldn't a glassfiber or epoxy coating be a better idea?

I've seen "stone lined" tanks and plastic lined tanks and of course stainless. I'm thinking if it were remotely a good idea, one of the many manufacturer's would be doing it.

I'm thinking copper's a bad idea because of certain corrosions AND, its possible for a bad reaction from the anode rod.

I thought most tanks are made of steel with a vitrified glass liner fused to the inside. Usually good for 20 years+

Surely good stainless would be fine on its own, probably more expensive though. I never did understand why they are (still) made of copper anyway, whats the reason?

Nobody posted a true answer to "Why do we use copper for such tanks?", more the answers is "We just do!".

Although Stainless might be more expensive, it transports heat significantly SLOWER than copper, so would actually be in comparison, a slightly better insulator in that respect, but no matter how aggressive the water, it should come through still "Stain-less!!"

But what the hell, stay with copper for all I care.......I do not store hot water anyway, its all "on demand" with us in this house!! No bulky hot tank to situate, no bulky cold water storage, no possibility of Legionnaires Disease etc etc etc....I am happy.

Although Stainless might be more expensive =

it is very much expensive compare to copper line hot water storage tank. The business owner can not afford the cost in reality. for your residence, maybe you might afford to buy that. However, in residencial use, you might need only maximum of 200 liters tank capacity for your family use, thats it. i dont think any manufacturers of water heaters uses SS sheets on the tank.

I am referring the hotwater storage tanks in a large volume consumption as i mentioned especially for the Hotels and hospitals.

I a modern system design of hot water system, the main distribution lines are contineous circulated to maintain the required hotwater temperature at the nearest outlets of the user especially in hotels and hospitals.

My only concern is that, are you familiar in copper lining method? Thanks anyway.

Just buy you a commercial grade 80 gallon tank that will meet all requirements!

80 gallon capacity is quite small tank which can be buy in a commercial store or distributor. The heating methods will be electric heater, probably single phase voltage.

This tank cannot cope up the consumption of a hotel at 150-250 beds capacity or hospital with 200-250 beds capacity.

Most likely, 2-3 tanks of 6000 liters storage capacity with a source heating is Hotwater or steam.

Copper lining tank specs is most common and cost effective and is availlable in the market and being accepted by Hotels & Hospitals. copper materials do not attack by corrosion as submerged in the water. Scale build-up will be the problem issue only as the water is being heated. However, maintenance sched will resolve the problem on a PMP (Preventive Maintenance Program) of the company itself based on the water quality as supplied.
