Read the customer reviews on the Titan. Like most other electric tankless that I have seen, the reviews are mostly negative. Seems our competition is not very formidable!
The Titan product consumes 54 amps of electricity. 54 amps is more energy than most electric stoves. Wdrp's unit plugs into a 15 amp outlet. If you plug into a 15 amp outlet the max amperage is 80% of 15 which is 12 amps. So if at a max is 12 amps divided into 54 amps for the Titan. wdrp's unit will be about 4 times more efficient
