Absolutely. An above ground tank with a valve on the bottom is definitely more susceptible to freezing than one off the top. Valves off the bottom of outside tanks can be the cause of oil spills as well because either something hits the valve and cracks it or I have seen water freeze in there and crack the valve. It happens.

When the line is put in the top of the tank they should put the copper until it hits the bottom of the tank and then raise it about 2" from the bottom. This will help to not get water in the lines. The other thing that could be done at the same time is to have them run a second line to your burner which would basically make it a self-priming pump. I would highly recommend getting the second line installed because if the burner is running when you get an oil delivery with a single pipe from the top of the tank it can get airbound and you will need to prime the pump yourself.

You also should have a tank gauge and a vent installed. If you don't, then get one. I ran into a customer that was burning out fuel pumps on his heater. Turns out that there were no vents in the tank and it actually pulled the tank into a vacuum.
