Venting a dryer in the garage -- make a hole in window or wall?

[nrv0us]

I am going to put a vented tumble dryer in my garage, which has a non-opening window.

How easy is it to make a hole in an existing window? Would that be the best place to vent the dryer, or would it be better to make a hole in the (breezeblock) wall? Presumably it would be a bad idea to just vent it within the garage -- the steam needs to get out somehow? Could I pipe it under the door and save making a hole altogether? I know I could just get a condenser dryer, but I hear bad things.

I'm no expert, but vent it through a hole cut in the wall. The hole is lined with plastic pipe and you shouldn't notice any kind of draught. I imagine you'd need a glazier to make a suitable hole in glass, but it would potentially be a security risk, assuming it's single glazing. Putting vents in windows seems a very old-fashioned idea.

Venting it within the garage would not be a good idea. Tumble dryers creates a lot of hot steam which could give you real issues.

you, or a small builder or large handywoman, can use a core drill (obtained from tool hire shops) to make a neat round hole in the wall. You may like to get the most out of it by making holes for cooker hood and bathroom extractor on the same day.

Core drills are rather heavy. Start from the outside.

a builder friend drilled through our wall with a core drill, took a while but did the job. You just need to buy a vent tube kit.
