Compute from basic thermodynamics analysis of the heat exchangers.
1.) The amount of power needed for water heater
2.) For 2 positive displacement pump to operate at,
d =300 RPM and
P = 150 PSI,

Using this information below:
Hot water temperature must be able to have a range of 60 degree Celsius to 80 degree Celsius
The input voltage was set at
V = 12.6V.
The device and thermal sensors that need protection from surges has a voltage rating of 12.6V
The time, t = 1 second
The current, I = 30 A
