I read this on the website
Suburban's ON DEMAND WATER HEATER is controlled from within the coach with either a standard ON/OFF switch and light (sold separately) or an upgraded On-Demand Control Center (sold separately) available in black or white. The On-Demand Control Center provides precise temperature control for reliable and consistent comfort from the convenience of your RV.
With Dimensions of 12.496" H x 12.449" W x 20.441" D, the IW60 ON DEMAND WATER HEATER is sized to replace any Suburban 6, 10, 12 or 16 Gallon Tank model or any Atwood 6 or 10 gallon model. An Access Panel, and Vent Cap (purchased separately) are Required When Replacing Suburban or Atwood Tanks.

42,000 BTU -should- heat 35 degree water to 120F "mixed" which is too hot for showering. But remember this. A gallon of vinegar at 150F in a regular hot water heater tank neutralized with a pound of baking soda will remove about two pounds of "lime" (mineral) buildup. Can't do that with a demand water heater.
So be prepared like I am preparing myself for a chew & spit piece of merchandise. It will enjoy a lifetime, finite by how much total dissolved solids it precipitates out of your domestic water supply.
I realize a standard water heater can sit there and inefficiently heat water through thick line deposits until it is hot enough to use. A demand water heater does not enjoy that luxury.
Yes this is peering through the wrong end of an optiminst's telescope but it is a fact that should be made known.
I am opting for the demand heater albeit a household model, despite this wart.
A five gallon pot has now gone three months powering the stove. When a brand new 17.5 gallon tank heater was set halfway up the scale the same pot lasted me 12 days. Showering once a day. One person. 15-minutes. Warmed 17.5 gallons ran out just as I rinse my hair. Warmed is not hot. The heater is a scumbag made in Mexico model. But it was purchased and installed by the owner three days after I moved in. And three techs have checked it for flame color and leaks from the tank to the burner. I am not going to blow fifty eight dollars every two months to have water than runs cold at the end of a shower.
