The calculator assumes the mash tun is preheated.
I will add a note about that.
Some of the other calculators try to account for the mash tun temperature.
They need additional information like mash tun specific heat,
which is a bit of a pain to figure out.
For batch sparging it seems easier to just preheat the mash tun.
