Not true. Steam has higher operating costs. The 800 draws about 16 amps vs a bypass that uses no electricity.
But they do work exponentially better. Bypass and fan powered humidifiers usually only hold set point in nice tight houses.
That being said, if your house is extremely loose, the 800 won't hold it either.
Don't install it in the 120v configuration, even though it is an option. If you have a softner, source the water before it gets softened, unless it is extremely hard (above 30 hardness).

Higher initial cost yes, but lower operating costs and they actually can hit your humidity setpoint vs a bypass style that can't.

Steam has lower operating costs than a bypass.
A bypass flushes 3 - 4 gallons of water down the drain for ever gallon it puts into your air.
A bypass - to help maximize it's inefficient design - needs to be hooked to a hot water line, so your water heater is running.
A bypass - again to help maximize it's inefficient design - needs to have your heat source running, especially if it's a heat pump.
Unless you do those last 2, there is also no way a bypass can humidify your home, therefore it's a waste of money.
And we haven't even talked about the organic growth problems the bypass has...
