An insulated air pot for hot water and the like has a hinged circular cap on the top of which there are arcuate indicators showing the volume and temperature of the liquid in the pot. The volume indicator comprises an indicator hand coupled with the upper end of a twisted strip which slides in a slot in a float member so that it is rotated as the float member rises or falls. The temperature indicator comprises a thermometer of arcuate shape having a bulb in the upper end of a heat conducting conduit. A ball valve at the top of a discharge pipe closes the pipe except when liquid is being discharged and thereby conserves heat.
