Can you vent a tumble dryer up and out?

[GreenerWithTheScenery]

Thinking of having a small extension on the back of the house, which in turn will cover where the dryer currently vents.

The position of the dryer in the kitchen is such that I could send the pipe up through the ceiling and and vent out over the top of the extension flat roof. Would that work?
Trying to think of solutions as moving the dryer isn't really possible.

I'm in the market for a heat pump one at the moment and have a budget of about €450 which seems to be enough. It's only the top end ones which are £800.

I've been told to get one with humidity sensor as well. Looking at Beko, they seem good value for money or a cheaper Bosch/Siemens.

And yes they are meant to take longer but that doesn't bother me at all. Currently it takes me days to dry clothing.

My vented one, I just stick the vent out the window when I used it, so didn't need to permanently vent it. So mine had been in various bedrooms over the years (as a big tv stand!)

Have a condensed one now in kitchen (included in washing machine) and hate it, not as good as my old vented one.

That might be because it's a washer dryer rather than because it's a condenser. Especially if you're trying to dry an entire load straight after washing. You generally need to run smaller loads if you are doing that or take half the load out, dry, put other half back in, dry, because the drying capacity is always smaller on washer dryers (it seems completely counterintuitive to me).

Yes could be. As soon as I move it will be back to separate again, even if it does have to go into a bedroom!

my condenser drier was about £250 and is great!
