Not to make light of what blows peoples' minds, but it's really just very basic high school physics (now adays my kids are learning this in middle school).
You need a big enough electric heater or gas or oil fired heater so you can heat up the water. For example,
2 GPM = 1,000 pounds per hour of water (this converts gpm to mass flow)
Let's say typical water temperature rise required is 40F to 90F, so 50F temp rise.
Since it takes one BTU to raise the temp of a pound of water by 1F:
1000 X 50 = 50,000 BTU per hour heater required
50,000 BTU/hr is 14.6 kilowatts in electrical terms
