Found an old 7.5L hot water urn. Any use??

Alrighty Guys,

I'm looking into making up a brewery for an all grain set up. I have came across an old hot water urn with a broken element & the usual tap fitted for making cups of tea, only problem is it's only 7.5L capacity.
I wondered if I could utilise this as my mashing boiler (sorry if my terminolgy is crap, hope you get my drift) or would it be too wee?

Seen other such things used on various posts, but they were all about 25L in size (& working) hence my two fold prroblem, maybe worth a go, but I suppose I would only get a quarter of a normal brew for the same amount of work.

You could use it to create a heat exchanger for a HERMS (Heat exchanger recirculating mash system.) Filling it with copper pipe, pumping the mash liquor through it and turning the element on and off periodically to produce temperature steps in the mash. Don't worry - it took me at least a month to figure out whats going on with these systems and I'm pretty sure none of us around here use anything that advanced.
