LOL sounds great, as gallon one enters the first chamber, it fires, then gallon one moves to chamber 2 and it fires, etc. But wait, gallon two has already entered chamber 1 while gallon 1 is at chamber 2, 3, or 4 and that magnetron is firing.
Maybe odd gallons use odd chambers and even gallons use even chambers? LMAO
The advantage if any will be the speed of transfer of the energy at molecular level and savings of no residual heat in standby mode over traditional resistance electric exchangers, and recapture of magnetron heat from water cooled mags. If radiation can excite all the molecules instead of only those that touch the element, and thereby the warm up time is eliminated and the cool down period of waste also... we may have something....we shall see. Point of use is more likely than whole house IMO. GLTA!
we have been there already, as Beers' reply hints. if you have 4 magnetrons, and only 2 are ever firing at the same time, then the max heat you can put into the water is the sum of the ratings of 2 of the magnetrons. with 4 rated at 1500 watts each the total heating ability, 6000 watts, is way below other electric tankless units that claim to supply a (one) small bathroom usefully
