Both technologies are dominant, but since the cost of a good quality HX is pretty much the same as a good quality DB, to me, it makes sense to go with the latter. I will get more precision when brewing and a more energy efficient machine. (ability to turn off one boiler).
Not necessarily. An HX has 1 larger boiler with a smaller volume to area ratio so it loses less heat.
Somewhere I calculated the energy saving of the DB steam boiler to be about 70w. I didn't measure the heat input on the smaller DB brew boiler, but the element is ON a LOT more than on the HX.
