danepak: Thanks all.
Order cancelled and I’ll be looking for a condensed dryer.
Would a heatpump dryer be good as well?

go for the heat pump

The issue is that we really would like it wall mounted.
We’ve got a nice stone bench top and really a waste if we have to put a dryer on it.
Both condenser and heat pump dryers are too heavy to wall mount.

can you not put it under the bench next to the washing machine?

Unfortunately not. We've got built in cupboards there.

could you not remove the cupboards and out something on the wall where the dryer would have gone?

just sounds like it wasnt thought out very well from the beginning, more of an afterthought

Yep, agree. Wasn’t thought out very well.
We’d hoped for a bit more assistance from the builders. They’re the experts and we pay them 😕

danepak: The fan is connected to a pipe that exits the building through a wall 6.5 metres away.

Have you got access into the ceiling above the laundry? Then you could attach a Y splitter on that pipe at the laundry end, for a direct connection to the dryer

If it was my place, I 'd see if I could get the ducting off the back of that fan in the ceiling and see if it would flex enough to attach to the rear vent of a dryer. You might be able to mount a dryer above the washing machine. Rear vent it straight up through the ceiling and flex the ducting to attach to it. Does mean another hole in the ceiling, so would depend on where the ceiling joists are. Would also need to check on what the manufacturer says in terms of the vent - there might be limits of length and rise of the ducting.

I think I remember reading that up to 10m is fine for driers to push air. If you can do without that fan just connect the drier to that duct.

There’s a sink above the cupboard and pipes etc beneath (inside the cupboard), so not possible

F&P recommend no more than 2m and 3 bends before going to probably a fan assisted duct. Metal pipe apparently picks up less lint. Even with a very short duct the dryers seem to push lint out of any gaps in the cabinet so it's worth sealing any air leaks.

Got the following from our builder:

I have also attached product information confirming the Contour laundry fan installed on a 6m duct will achieve over 72 l/s exceeding the 40 l/s required for laundries with unvented non-condensing tumble dryers as cover in the code.(see notes at the bottom of the Pressure to Perform leaflet.
As you have expressed concerns about the capacity of the fan to ventilate this area we has offered to upgrade this fan, at no cost to you, for the high steam area fan which will ventilate nearly 120 l/s.

Nice of your builder to do that, but it should really be ducted in. I guess your room will end up really moist with condensation issues and some will leak into the house. Unfortunately adding a duct now will make it look a bit ugly, so it's a toss up between adding moisture to your room and a condensing drier.

OK, so you don’t think the powerful fan will make a difference?

I think it will make a positive difference. My question is will it be good enough? Best let someone who has a similar setup guide you, as I have no recent experience.

I vented my drier by cutting a hole in the exterior wall when I got my old drier 10 years ago, when we replaced it recently and moved it we just ran white ducting to the existing hole. Looks ok.

I'm considering getting one of these. I'll then be able to monitor the humidity. Not sure what level I would want to be under though, to ensure that the humidity isn't too high.
