Consider a Zojirushi, it will keep the water at 208 just off the boil,
there is a reboil button if needed, and they are available in a 5Liter
size. 5 liters would be enough to give everyone a cup before you
needed to refill and then just top off the water once in a while using
gallon jugs of spring water as people saunter in for their second
cuppa. The beauty of this solution is you wind up with a device you
might actually use yourself after the event is over.

I have been using one now for over year and I love it.
