Can the air inlet duct on the RTGH-84DVLN, which is separate from the exhaust, be ducted simply to use warm air from inside the building?

According to my plumber, no. He installed both ducts, inlet and exhaust thru the wall.

I did mine like that and has been working just fine. Installed October 2014 inside garage. So far so good

Hello Richard, I had the same dilemma and I decided that the fan would be much more effective when used as an exhaust fan. I have a very hot running tube amp and it keeps it running warm. I did angle the cabinet to the back wall so that the air would be reflected away at about a 15 degree angle. Hope this helps. Jnm

In my opinion - MAYBE. It comes with a four-piece hard plastic, sort of "vent stack" with top connection curved as if to direct the warm air that comes out of the dryer towards an outlet for the hot air. I can roll mine right up to a window so I didn't need to buy flex-duct or anything to extend its venting. In the instructions it said something like - if you prefer not to vent the dryer through a window, you may just enjoy the 'pleasant warming' it will provide to your room. Must be cold year round in China, huh? I didn't mind a little 'warming' in Jan-Feb. But it's in the 90's now in NYC. Don't think I'd want to run it unvented in a windowless room today. But appears - from the instructions - to be possible; although maybe not always a practical idea. But that's where we come back to the flex duct - you can buy that stuff by the mile I think, if you need to.

Yes, AND to pull fresh air return. The rear of the cooling unit has 2 airflows, exhaust and return. The duct fan will assist with both airflows.

yes, you won't need ducting inside the tent ,but outside where you want to vent the air (and odor) to, you may need ducting. Hope this helps

You must funnel the heat coming out of the rear exhaust to the outside or another unused room, or you are simply moving the air around in the same room using a lot of electricity (With no beneficial cooling). RJK

Frankly if the cabinet is open, you do not really need the fan. Biut given the choices, I would pull air through the front and exhaust to the back.

No. It's a continuous-duty fan that runs very quietly and balances temperatures between two or more rooms. It's not a high-volume (CFM) fan, so continuous operation is part of what enables it to keep room temps balanced. It does have a speed control, and it is highly effective at about half-speed. I use mine to push cold air (farthest corner of the room near the floor) out of the "cold" room and into the warm room. Meanwhile the open doorway from the warm room to the cold room replaces the cold air with warm air near the ceiling. You could reverse the air movement...placing the fan high and pushing warm air near the ceiling from the warm room into the cold room. But this makes the fan far more visible. In my case, I was able to place the fan low...behind a night stand...and push the cold air thru the wall and into the base of a stairwell that ties into the wood-stove room. The more separation between the fan and the air flow in the other direction, the better. For example, if you put the fan above a doorway, the fan would move air from the warm room into the cold room, but the doorway would short-circuit the air flow and create a small loop into and out of the cold room that would not heat the room well. I've been using my fan for years, and I've yet to fully disassemble the cabinet and clean the fan blades or motor. It's very durable, quiet and effective...my neglect notwithstanding. I simply vacuum the intake and exhaust louvers occasionally, because the get quite dirty (wood stoves are dirty). I turn it on at the beginning of the heating season, and shut it off in late spring.

I don't think so, fans are designed to suck air through one port,unless fan is reversible,do what I did and buy longer inlet ductwork.

Yes, you can set it on "heat" and set a minimum set point for the fan to come on. I use the low speed for winter heat. I have the fan come on when the duct temp reaches 68 degrees. It runs until the furnace cycles off and the duct cools down below 68 degrees. Then it automatically shuts off. In the summer I set it on the cool mode and have the fan on high. I also use a different set point for that. The sensor works well. My only MAJOR complaint is that the summer fan is tooooooooo small. With all this technology the summer fan dosen't have enough guts to cool my bedroom. The winter is good, the summer leaves me complaining. So, it all depends on what season you really want this for the most. Good luck. Yes, you can set it on "heat" and set a minimum set point for the fan to come on. I use the low speed for winter heat.

we use it in a duct to circulate air that sometimes reaches 140 F and run it at that temp up to 3hrs

This naturally follows the duct air flow and can enhance output of air into the room with a fan. It does not intake air from the room.

The one I got was for non-ducted use and came with the interior ceiling mounted controls. It did not come with anything to heat.

The intake port brings outside air into the unit to cool it. Blocking it off means you will be using cooled air from the room to cool the unit. Also, you will create a negative pressure situation inside the room that will suck warm air into the room from any cracks around windows, doors, outlets, etc. to replace the cooled room air that gets warmed inside the unit and exhausted outside through the exhaust port. I suppose it could be done, but the unit would not be as efficient as it is with the intake and exhaust hoses connected to the outside.

Yes, you need to duct. In an office building, we ran the exhaust through a ceiling tile into the plenum. It did not effect our air balance and seemed to work fine. In other types of HVAC, you may need to hook into the return air duct.

Only if you want to use the internal blower( which does not move very much air). I use a extra regular fan to circulate air in the garage.

I would say no. This fan mounts in the wall. It fits through the thickness of the wall and vents directly to outside, using no duct. If you need to use a 4 inch vent pipe, I would buy a fan made for that application.
