I will just Quote this guy, ohh wait that was me, I keep things simple.
One note as your talking about steam humidifiers.
Steam humidifiers are the WORST New product out there, my work went through HELL with them, typical fashion we were sold on them by the " Ohhh my Lord its new and cool and technically advanced "
But after 3 years to date of melting Boards, melting plastic ( dry firing ) and constant calls of " my electric bills are very high " we decided to do the Honorable thing and replace everyone that we came across that we installed. There is not ONE company ( maybe I guess ) that would do this, but we are very honorable, we have finally replaced them all with Aprilaire 700A's and everyone is happy !!!
I think we sold around 20-25 total witch is quite a bit as they were not cheap to install...
Yes you read that right, we installed a NEW fancy product and had such a massive FAIL that we felt very responsible for it and corrected it by installing what we enjoy installing because of the High success rate, were talking 12-15grand.... YIKES !!!
The steam humidifier was over engineered similar to somebody's posts :goof
