Hi Mason, One of my uncle's lived in San Mateo for 40 some years while
working for Delta Airlines. I stayed with him for two months after being
discharged from the Navy at Treasure Island in '69. After he retired he
moved to Sacramento. At any rate on to your tank situation.Through my
involvrment with bee's in the late 50's the most practical method I've
seen was a 5,000 gallon tank on an upright stand with a well insulated
bldg. surrounding it. A thermost was used with  a simple space heater.
The tank was high enough off the ground where you could fill barrels with
the exterior outlet or one pound jars.The extracted honey went directly
into the tank for whatever honey flow was going on and then botteled
accordingly. Anyone can do the same thing adjusting the tank
size,ect.,for the size of their operation. I hope this helps.
