One of the main things to consider when sizing your evaporator is the gallons per hour evaporation rate and how much time you will actually have available to boil. For people with less available time that is more important than the size of the evaporator. Each brand and model of evaporator will achieve different gph rates. If you are undersized and end up boiling all night, you are less likely to enjoy it. Oversized will mean you might not have enough sap to boil without waiting a few days. People will start shouting out brands they are loyal to, but they may not be the right fit for you.
