Can this be used without the window exhaust kit? is there an internal bucket to collect the water?

The exhaust always has to be vented somewhere. And it gets rather hot so It would be counter productive to not vent the exhaust outside. I believe that when there is water to be collected its because of extreme humidity. Otherwise it should be necessary to collect the water

We have not been able to find an access to an internal water bucket but have not had any problems with the unit. No water overflow or issues with cooling. We have never used the unit without window exhaust kit.

The quick answer is I don't know. However, I would note there is apparently a small tray at the bottom (others have mentioned this). The basic problem I see with not installing the exhaust is where is the hot air supposed to go? You can, I have, have the pipe go out a homemade baffle. I did this since the one that came did not work in my window. Hope that helps.

The unit is designed for outdoor use. It has intake and exhaust built in. So you do not need additional venting.

It only requires one hose for the exhaust. One is the intake that doesn't require a hose to be hooked up to it.

Yes, we do have intake and exhaust to the outside. The drain is a small outlet at the very bottom of the unit that is hard to get at. We currently have the unit up on a small bench with a dish pan underneath. The drain is left open and drips constantly while we are running the unit. The dish pan fills up after 4 hours of running it so we have to remember to shut it down and empty the pan from time to time.

The exhaust system for the window consists of an adjustable panel that you sandwich in between the frame and the sliding section of the window. So if you have access to the track/frame of your window you are good to go. If there are screens on the inside blocking access to the track, they will be in the way, and you wouldn't be able to use the exhaust parts as intended

No only exhaust. I use it in a sunroom wall to take the heat out duing the summer months here in FL. I have also seen it installed on hatches of sail boats.

I guess one could add another exhaust extension tube, if one could find a way of attaching it securely to the tube that goes from the unit to the window. However, the end of the tube that goes to the window has a special ending that will lock into the window panel. Maybe that could be pulled off and an extension tube added, but I don't know how.

Jacob, The machine has the ability with a secondary opening for an intake. (at least the model that arrived when I ordered in July 2014). Your only issue would be that the package doesn't come with an extra hose, hose attachment brackets, and the window adapter only has one opening for the output. Maybe it is possible to order those minor pieces from the manufacturer.

You need the vent system. I used the following: "Rinnai 223176PP 12-Inch Condensing Horizontal Termination Kit" and "Rinnai 224079PP Condensing Vent Pipe Extension, 19.5-Inch" The black part of the "Termination Kit" goes outside and the elbow connects to the extension. The water valves and relief valves are included with the heater. That is it. The rest of stuff you need you can get from the hardware store.

You will need a window or at least a place where you can put hose for exhaust

If you don't have any way to vent outside like windows or something, you might be able to build a water filter to clear the exhaust. It wouldn't be too hard and would only require some engineering and pvc.

It's a window unit. Exhaust side needs to be properly ventilated to the outside.

There is a siphon tube but it is not auto siphon. You have to get it started with water.

Only one flexible hose that comes with it. It connects to the window assembly to exhaust hot air to the outside. But it is only 5-6 feet long -- just enough for the main unit to sit very near that window. With only the one hose for exhaust, it needs to constantly pull in air from the house. I'm lucky to have a basement window I can open for that. If you don't have a basement, then you will have to choose a window in some other room not being cooled. Best if you can find one that opens to a shaded area.

This is a self evaporative unit. Water is expelled through the exhaust hose. You will only need to drain the unit if you live in a very humid climate. I'm in California, and I haven't needed to ever drain mine (used since 2010).

We've had our Koldfront for a few months now, there isn't any water. As the description states: The unit features an internal condensate removal system that will handle all but the most humid environments saving you the trouble of manually emptying a water bucket. This is very true, we've had no water issues. We didn't run our system 24/7, only as needed. I suppose it you use it 24/7 you might have water. What I'd also like to mention is this unit is GREAT! We have a 3 bedroom rambler and it cools the house very well.

We only used it out doors, you might be able to use a hose to siphon or empty it with buckets.
