<p>An electro-thermal heating system comprising a substantially hollow housing having detachable upper and lower plates for covering and sealing top and bottom surfaces of the housing. The housing has an inlet and an outlet for a flow of coolant to enter into and leave the housing, and has openings defined therein, for insertion of electric heating elements therein to project into the housing and be in direct contact with the coolant to heat it. The inlet and the outlet can be interconnected with piping to form a closed fluid flow circuit. The housing is substantially circular, to circulate flow of the coolant in a circular manner within the housing, and a diameter of the inlet is greater than a diameter of the outlet, to keep coolant in the housing longer to heat it. A pump and a power source can be interconnected to the system to circulate the coolant in the closed fluid flow circuit.</p> |
