There is a reason that hot air goes outside, its wet and will cause moisture issues blowing it into your house
It gets way too dry in my house without running a humidifier in the winter. Blowing the dryer exhaust inside the house helps a lot but not enough to keep it from getting too dry. It the summer it would definitely be a problem but so would the heat.
Same here, actually went with an in furnace humidifier as I was tired of carrying water to the other. Went with a Autoflo S2020, think it will add up to 21 gallons a day.
Since it came up, picked up a scratch and dent front load washer last winter when we got back from the UK as the wife loves the ones over there. Have the older Calypso for work clothes, the front load is for good clothes. Worked great for 3-4 months then the clothes started coming out excessively wet, they have a sensor that works off pressure to gauge how much water is in the tub, called on the warranty and they actually sent me a new one
Installed that and it still did it, turns out from being over full of water it got out of balance once and the hose that goes to the sensor came loose and the motor rubbed a hole in it. A trip to the local garage for a piece of vacuum hose solved that, also drilled a few small holes and used zip ties to hold it in place so I'd never have to deal with that happy crap again. FWI, for those that have the new HE washing machines that feel you want more water in the wash/rinse cycle, simply change that hose going to the sensor with one several feet longer, a larger volume of air in the line means it takes more water to build the same pressure at the switch.
