What is the best and cheapest way to heat a brick and sand driveway 39'x16'? I am replacing my old asphalt one this summer. I was thinking of using an instant hot water heater, submersible pump, timer, and cpvc or pvc 1/4" or 1/2" pipe recirculating an antifreeze mix in a 5 gallon bucket. Would this work?
