I used a boat tank for my diesel,fattywagons wires to heat it,and heatexchanger.The wires I made a thermstat to turn off heaters,when heatexchanger was hot.I had manual valves.But I did a mistake by using main tank for 50/50 mix.The animals proteins ( the dreaded chicken skin ) took two years to clear from tank.
