On the 84 vintage block in my 77 coach the heater was low on the passenger side of the block towards the rear as the engine sits in the coach. Given the additional amps it is drawing, the heater element is the only possible cause since the wiring would go up in flames absorbing that much power.
One caution I was told by my DD dealer was to be sure the power to the heater is shut off prior to starting the engine. At start, the are times when a big slug of air gets pumped through the engine and if the power is on there is nowhere for the heat to go and it toasts the element.
