I don't know what sale switches, pressure compensated flo switches are, all I know is I turn on the hot water faucet, and hot water comes out. So I'm thinking all that fancy stuff is just there to raise costs, not because it really offers a tangible benefit.
Reminds me of how installers only offer solar systems that cost thousands of dollars, so homeowners think that they either have to finance, or not solarize at all - but they only offer high kW utility intertie systems because that's what they can make the most mark-up on, not because its all that is available. My solar system cost a few hundred.
