Scorched Air vs Hydrocoil
Good evening Wallies,
Always pondering, looking to learn & butting heads....this time was butting heads with a contractor. Not buying into his cheap workmanship and manipulation tactics.
In the world of forced error, there are two systems that one usually finds. Those two are furnaces and hydrocoils fed off of a boiler. It is my understanding that the hx on a furnace is no different then a hydrocoil heating the air. One has water flowing through it and the other products of combustion. Given the same surface temperature (coil or furnace hx) one would assume the air in the vent would have the same humidity level. I could be wrong though, and that is why I am writing on the wall. I have read Manual-P on psychometrics, but never polished the information.
Todays "heated" discussion was with a contractor who claimed that with any forced error system the air is dry and one would require a humidifier to add moister to the air.
His claim is that any hydrocoil that has been installed in the homes he built have customers that rave about the air not being dry. I think he and his client are full of hot air.
It is only logical to me, that with the correct airflow, and proper condensing furnace, one would replicate the hydrocoil.
If im wrong, quickly delete this post before he finds it.............only kidding.
Discuss so we can all learn.
