19.03 Does an aboveground tank need to be heated?

Tnak heaters are available for heating of aboveground tanks in cold climates. However, many aboveground tanks are not heated if a winter blend of fuel is used.

Part of the thinking in not heating the aboveground tank is that the fuel will rise in temperature before it reaches the generator by: (a) movement through a pump, (b) movement through heat traced and insulated piping if used, and (c) storage within a day tank if the day tank is located within a heated room or enclosure.
