Solar copper tank
« on: March 20, 2017, 11:44:33 pm »
I have a large solar copper tank in my bathroom for my domestic hot water .
It's also linked to woodburner.It's about 12 yrs old and had a little leak 3 yrs ago which we managed to have repaired.I have had a new tank made which has been in my shed for 3 you think I should replace if now.We are in a hard water area.
It's such a large tank...could cause a lot of damage if it leaks again.
My ideal would be to have a house with no storage tanks at all....gas central my dreams

I certainly would replace it Juliem- immediately. It's not the size of the tank that determines the amount of water leaked, but it is the rate that the tank is refilled from the header tank above.

Difficult job I know, having replaced many. The pipe work positions may need adjusting but the two important things are the condition of the floor beneath the tank and the sealing of the fittings to the tank. The latter will only be known to be OK when the whole tank is refilled. Best to use the gas grade PTFE tape (which is thicker than standard) on the treads of the fittings to the tank which should all be new anyway.

Think logically Julie:-
 Your tank has leaked once so you know it's on borrowed time.
 You have a new one to replace it with.
 You will therefore have to replace it sometime. So why wait until it becomes a crisis?
 If gas central heating is at present only a dream, then it sounds unlikely that it will happen before your old storage tank leaks again and becomes a nightmare!

 :asked my plumber and he reckoned needs to be done on a cloudy day....he seemed to be concerned about the liquid in the vessel....I assumed this would not be affected because there are those little cut off valves all over the place.
I had hoped it could be a project for the summer...but perhaps not

I'd look for someone local in your local freeads/newspapers. Obviously you don't need someone with all gas safe qualifications. But any experienced plumber should find it straightforward.
