Okay, I see now. This is not connected to a furnace and uses hot water as the heat source. So you can't go with cold water for the the feed.

Link I found online says it uses up to 6 gallons of water/hour so I could see it causing a lot of short cycles.

The online version of the manual says that the feed water should be 140 F maximum. It doesn't say anything about mixing it with cold water.
