# BN-LINK Mini-Tank Water Heater: A Much Heavier Box Than Usual > Looking over the tank, controls and supplied installation material without plumbing it in.

It costs you nothing extra, and it has not changed what this article says — where a competitor is the better answer, we say so. This box is a little outside the normal desk-gadget routine. It is a BN-LINK mini-tank water heater, and lifting the inner package tells me it is heavier than its size first suggests. ## Open the hardware before planning a connection I look over the tank’s label, then find the installation manual, relief valve and supplied tape. On the body, I point out the water connections, power cable and temperature control. Those are the components coming out of the box. I do not connect the plumbing, fill the tank, wire anything or power it up for a heating test. ## Why the small tank interests me I talk about the idea of having hot water closer to where it is needed instead of waiting for it to arrive from elsewhere. That is the use case I am interested in, not a measured result from this unit. The label’s capacity and electrical ratings are also specifications I am reading. I do not test heating speed, pressure behavior, efficiency or suitability for a particular room or vehicle. ## Installation is a separate job This first look is not a plumbing or electrical installation guide. The actual installation requirements still need to be worked through with the supplied manual and the appropriate qualified help. For now, I have a better idea of the size, weight and controls of the unit I want to try.
