We will be in site summer of 2011 and have access to 250 gal lp tank. Not sure if we want to use it yet. Was wondering ,will we have to add different regulator or can we simply hook into the regulator from our 30lb tanks? The installation of the tank will be done professionally but dont want to get too big an expense and dont really want a regulator to mow or trim around. Reason for the interest is for heat in early spring and late fall.
