Actually I did try that and maybe I am remembering from older times but the threads I bring up only seem to be about designing an upstairs laundry room. I am wondering if there are specific models that are better than others for upstairs. (vibrations, noise,??)

Electrolux has a 2nd floor guarantee

I have a set (last year's model), they are installed on raised platform on our first floor, the vibration is minimal and I wouldn't see an issue with using them upstairs.

I am coming around to thinking that it might not pay to install the gas line for the upstairs dryer. Although we did have at least 3 people come by to give estimates, we have yet to receive anything in writing with numbers. They did all indicate that running the line up 2 floors (from basement to first floor for range and possibly fireplace is one thing and less involved--- but to the second floor is another thing and of course it is different walls)would be more involved.

I tried to find the information which we used to see ( I swear as recently as last year for sure when we were looking at other appliances) the yellow sticker sheet which would give average yearly cost to run each appliance. At first I thought it must have been a state requirement as we moved to a different state. I tried looking on various websites and even calling HD and Maytag just for example and apparently this information is no longer available. Pretty disappointed. the best I got was someone telling me that in general gas would be cheaper. If I could get a ballpark figure I could try to compare apples to apples but this is not in the cards. I know a gas dryer is typically 100 more at purchase. My hunch at this point (and since I can't get a $ figure from contractors yet) that it would likely cost around $700 to $1500 to run the gas line for dryer. I think it does not pay for moi.So I am looking at electric dryers and still looking at washing machines.

The sales are pretty strong coming up for labor day...

Running a gas line through an existing structure for a dryer makes zero sense to me. Sounds like you are dealing with a laundry "closet." Look at Bosch 500 or 800 machines with ventless dryer. I got the 500 set 8 months ago for a closet and it's been excellent. This is a compact set but I've yet to have a full load. It holds quite a lot.

The washer plugs into the dryer. So all that's needed is a 240v plug for the set. It is quite and nearly vibration free. These units are designed for laundry closets. Other brands make the same types of units.

You would want to make sure that you waterproof the units. Some Bosch machines have built in waterproofing - double lined extra strong hoses with a pan that turns the machine off if it senses water. You can retro fit a pan and water alarm.

Is size a consideration? Are you going for stackable units?

They have washer pans at the Home Depot. They were around $40.

salonva: You need to specify the width, depth (with the door closed), and height of the closet, whether there is a vent for the dryer, and the voltages and ratings (in amps) of the circuit breakers to which the outlets in the closet are connected. You have a lot more choices if your closet will accept full-size appliances than if only compact appliances will fit.

Yes this is a big closet with full size appliances currently. I can measure but there is ample room. I have the ironing board (folded) standing up next to the dryer. Each appliance is on the floor, not stacked. Actually a front loader will work there, but I am not 100 % convinced that front loader is the way to go.

There is a wash pan (but we will get new)- I believe it is code here for an upstairs laundry room to have the drain with the washer ... I like the idea of the of the automatic shut off.

Be careful with the automatic shut offs. Great in theory but in reality the newer low water usage machines mess them up. We had to uninstall ours.

salonva: I'd start by checking Consumer Reports reviews and recommendations, supplemented by anecdotal reviews at sites like Home Depot and Best Buy. The scariest reviews contain reports of leaks; these seem to be most common for front-load washers. Check the specs on the manufacturers' websites for the appliance dimensions and clearance requirements. For a second-floor installation, check that the floor is strong and flat to reduce vibration. You might also consider installing a detector that will shut off the water in case of a leak.

Around here we will recommend front loaders. We even converted mamapinky because with a front loader you can get a true hot wash. I had a top loader for 6 months in a brief rental and it had begun to shred a set of my sheets. For me, no comparison.

In Consumer Reports' testing, front load washers were, overall, gentler on fabrics than HE (no-agitator) top loaders which, in turn, were gentler than agitator top loaders. However there were several recommended HE top loaders whose gentleness was still rated "good" (but not "very good" or "excellent").

Again, no true hot washes with any top loader. CR also recommends washing everything in cold water. Most of us around here disagree with cold water washes except for certain synthetics. But synthetics do very well in warm water. I cannot remember the last cold water wash I did but I like really clean results.
