Does this set need a gas line?

Yes. The dryer is a gas model, so it needs a gas hookup and a vent to the outside. If your laundry room is all-electric, look for the electric version of the same pair.

Can the washer and dryer be used side by side instead of stacked?

Yes. The stacking kit is optional, so the pair can sit side by side if you have the width. Stacking is what saves the floor space.

How big is the washer compared with other LG front loaders?

The drum is 4.5 cu. ft., which is mid-to-large in LG's range. LG's largest front loaders go up to about 5.0 cu. ft., so this set gives up some capacity for a smaller footprint.

Does the washer work with the LG ThinQ app?

Yes. It supports remote start, cycle downloads and diagnostics through ThinQ. You need Wi-Fi and an LG account to use those features.

What is included in the set?

You get the front-load washer, the gas dryer and the stacking kit needed to join them. Hoses, the gas connector and venting are usually sold separately, so check before installation day.

Is this a good choice for a family?

Yes, for most families. The washer handles large loads, and the gas dryer dries quickly. Very large households may want the bigger drum and a matching-capacity dryer.
