Do you have to have the exhaust from a clothes dryer go outside?

Is there any reason not to use a clothes dryer exhaust as a heater? Does too many particles make it out even with the lint filter?

They make a dryer exhaust hose that has a vent and a valve in it. You can open it in the winter and shut it in the summer. Has a small filter in it too, if I remember correctly. Menards carries them......

It was a common practice to vent dryer exhaust into the house for heat, however that practice is no longer recommended because it will promote mold/fungus growth in the house.

yeah not to mention that after playing around with the exhaust hose the lint filter leaves a lot to be desired.

Humidity would not be much of an issue though since it's in the garage.

Heh it's gas powered I just realized. There is a good reason not to.

A typical dryer load uses less than $0.50 of energy, therefore the saving isn't significant enough to risk damaging your expensive home & lower the air quality (soap/perfume/lint).

Throw on a sweater, and lower the house temperature by a couple of degrees would make a much greater energy saving. Programmable thermostat, and turn off computer/lights when not in use would be a good start with energy saving.

yeah it's in the garage though so it's not like it will ever get heated from another source.

Interesting answer but has nothing to do with the subject or what you quoted.

Something called Carbon Monoxide, unless that doesn't matter to you , or you have an electric.

put the exhaust into a bucket of water next to the dryer. no need to cut a hole in the side of your house

yeah + saying it's using so little energy costs has it making more sense to try it than not.

I'd say during a limited period it could work well to warm up a workarea. If you are only using this method rarely it's going to cause no more harm than a garage which is usually not so weathertight and has various things outgassing and drying anyway.

Unless the garage is a detach, other wise it still is part of the house and moisture & contaminants will make it into the house.

Natural gas give off water when burn, and it is required by (Canadian) building/fire code to be vented outside or operated under a vented hood. The reason is to prevent poisoning from unclean (improper) burned gas.

Most if not all newer garage have heaters (higher risk in insulated/vapor barrier wall) as a way to keep the area warm to prevent in wall dew point.

Back in my old house, we kept our cat in the laundry room when we were cleaning and whatnot, so he wouldn't get in the way. We had the dryer going, and he detached the hose...somehow. We heard him howling, so I opened door, and out runs a sopping wet cat. The room was full of steam, kinda funny.

It's not a great idea for heating the house. However, if your air is particularly dry during the winter (especially depending on the type of heating you use in the house), it's not that bad as a method for increasing the humidity in the house. They make an attachment for the vent hose that has a sort of valve so you can control if it goes out of the house or into the house. That coming into the house goes through an additional filter to help minimize any dust/lint making it through. Personally, I tried it once at our old house. At first, it made the air a lot better - not as dry. But, it's a pita to try to monitor humidity levels and crawl behind the drier to switch it to vent to the outside instead of into the house or vice versa. It *will* make the house too humid if you vent every load into the house. Carbon monoxide shouldn't be a significant issue with a drier, any more than the carbon monoxide issue with the burners on your stove when you're cooking.

I do this...it's a great way to add heat to the house. Just make sure the filter is cleaned often (lint is VERY FLAMABLE!!!!)

CO goes up from incomplete combustion. As long as the flames are blue (no yellow tipping), you are fine. Of course one cannot see the flames in a dryer. This should not be an issue unless the edifice is extremely tight and you're burning a lot of fuel using up too much O2. If your walls start sweating it's a sign of excessive humidity produced by unvented heating and your indoor CO2 levels could be approaching unhealthy levels. Best bet is to keep the hose venting outside.
