Condenser or center dryer

    Hi, need to buy a new tumble dryer for a small salon.

    Currently have a condenser but wondering would a vented be better?

    The room it's in is quite small and very warm (top of building) so I wonder does one produce less heat than the other as the room also doubles as a canteen.

    It's on an outside wall so putting in a vent isn't an issue.

    All advice appreciated

    Suggest you edit your post, click the 'go advanced' button and change the thread title, looks like 'vented' was autocorrected to 'center'.

    Send a photo of the place where it is located and measure the humidity in the room.

    If you get a heat pump dryer, particularly something suited for heavier use (Miele and Electrolux do ranges for small business) it would be ideal and they don't throw out very much heat.

    A simple condenser dryer basically dumps heat into the room. The air from the drum in the dryer is circulating in a loop through a heat exchanger in the bottom of the machine which is using air sucked in from the room to cool it enough for the steam to condense as it passes through. The result is your room gets pretty hot - almost like running a fan heater.

    A heat pump dryer works a bit like an air conditioner in a loop. The warm moist air from the drum passes through the cold side of the heat pump, the cold plates cause the moisture to drop out of it rapidly (condense). Then the heat that was removed from the air is used to re-heat it again as it passes through the hot side of tech heat pump. So none or at least very little heat is lost to the room.

    The better heat pump dryers are pretty fast and gentle too and extremely energy efficient (Like using 500-700 Watts instead of up to 3000 watts).

    A vented dryer will draw air from your room into the dryer, through a heater and then it just exhausts it straight out through a duct going through the wall. The downside of this is that you're basically paying to heat air that's being blown outside and also you're sucking warm air (or chilled air if you've A/C in summer) out of your salon and blowing it straight out through the wall. From an energy efficiency point of view, think of it as a bit like putting an electric heater in the yard.

    If you're drying lots of towels the heat pump will save you a lot of money (way more than in a domestic situation). The only downside is they're more expensive and if you want a work-horse type machine for a commercial premises you'd probably want to ensure you get a good one.
