Hey dekebell glad we could help,
A link to the tank can be found at

Menards sells them under the brand name TOOL SHOP.
A couple of helpful modifacations are:
Adding 2 inches of pink insulation foam (R value of 11)to the outside of the tank.
Glueing 2 windshield wipers to the bottom inside of the cover near the hinge prevents condensation from running down the back of the tank.
I just attach the incoming line of the filter system to the nozzle of the sprayer with a hoseclamp with which I replaced the screw with a thumb screw.
As for performance it heats up from 70 to 140 in about 40 minutes. when the lid is closed the heat element run between 5 an 10 minutes per hour. When the lid is open the element runs between 10 and 20 minutes per hour.
