condenser or vented?

I am looking to purchase a tumble dryer.

It will be located in the kitchen with an external wall directly behind. Creating a hole for a vented machine wont be too much of a problem.

I was after opinions as to which to buy.

I know that a condenser machine used more electricity per cycle but I assume it also heats the room. With a vented machine all the heat goes directly outside.

Is there anything else to consider?

Thanks in advance

Never ever ever ever buy a condensor dryer if you can fit a Conventionally vented one they take twice as long to dry and are less economical to run. If you can get a hose through the wall use the conventional.

cannot get much clearer than that.
