Now that the weather is warming up, I'm considering replacing our HW
storage tank (it's about 30 years old, and is getting a bit crusty
around some of the pipe connectors).Â* Before I do, I suppose I ought
to ask if (in everyone's opinion) I should just replace it
like-for-like? Or is there some other direction I ought to be heading
in, like mains-pressure hot water, or just using instant hot-water
taps everywhere instead?Â* Or something else?
I replaced my hot water tank with one that came covered with 2" of foam
which I then painted. Much better than the previous jacket.
Pre-insulated is nice - except then the previous tank is in a cupboard
that is big enough for the new tank, but not big enough to manouevre it
in. I had to cut of half-a-dozen central heating pipes and remove valves
and pump to get the tank in and then rejoin all the pipes.
I like
having an immersion heater as a backup in case my boiler is not working.
Me too, but ours has failed in an odd way. I am asumming that the
element has warped towards the stat tube. It works once and trips out
the overheat trip. I have replaced the stat a couple of times and the
problem remains. Of course the heater has siezed into the tank and will
not come out.
At least I can reset it and use it once if we really need to.

Have you tried automatic transmission fluid? It's an awesome unsiezer
Might be easier to just use a separate stat. Must be 13A rated.
I could use an external stat, but I'd also need to add an external
overtemp trip. The other option is to cut a hole in the tank and add a
new boss.
