Warning: This is for electric clothes driers only, NOT FOR GAS DRYERS
The heating element in an electric dryer draws about 5,000 watts. That is about equal to 4 electric space heaters. Keeping that heat inside your home is a good thing.
The normal method of venting electric dryers outdoors also pushes already heated air out of the house. That air is replaced by cold air coming in some where else. Your furnace needs to work harder to heat up that cold air.
The air venting from an electric clothes dryer is warm and wet. Most of us need both more heat and more humidity inside our homes during the heating season. If your clothes dryer is located in a damp basement, you might not want to add more moisture until you get the damp basement problem fixed.
If you go the quick and easy route of disconnecting the dryer vent flex duct from the outlet through the wall you need to do two things.
Seal the hole in the wall to stop outside and inside air from switching places.
Add a lint catcher to the end of the dryer vent flex pipe. You do not need any extra dust in your home. Some folks use a vacuum cleaner bag for this. Make sure you clean it out or replace it weekly. Even better get one of these Indoor Dryer Vent Kits
These kits include a lint trap and a section of flex duct plus the clamps needed to put it all together. These are great for folks with apartments who can not vent out doors. Make sure you clean the lint trap often.
Plugged lint traps waste energy due to poor dryer operation and can risk causing a fire. Clean all lint traps before every dryer load. Save money and prevents house fires.
Plugged lit traps and vent flex ducts are one of the most common causes of house fires in the USA.
There is a better way
Install the kit where you want the warm air to discharge, not in your face above the dryer. It comes with a lint screen. You can switch the lever on the Heat Keeper to either send heat outdoor or indoors.
The Heat Keeper is easy to install. It is usually mounted to a wall or beam beside the electric dryer. Make sure that it is not twisted or pulled out of shape. The plastic housing can be distorted and prevent the flapper inside from working right.
Locate the Heat Keeper for easy access so the built in lint screen can be cleaned by anyone using the electric clothes dryer.
Once mounted, the dryer vent flex duct can be cut and reattached to the Heat Keeper. Make sure you connect the vent flex duct to the right places so the air will flow as indicated by the arrows.
I have seen ads for a unit that goes under the dryer like a little platform. It makes a neat installation for an in the house laundry room. It costs about 10 times more and fat old guys like me don't like the idea of bending down to the floor level to clean out the lint.
Do not use duct tape.
Clamps on the vent duct ends are needed for a long lasting job. You may have to get some good metal clamps from your local hardware store if you wreck the ones that come in the kit, like I did.
Set the temperature selector on the electric dryer to hot and start the electric dryer for a test run. Check to make sure that the vent air blows inside the house when the handle is in the winter position. Move handle to summer position. Check outdoors to make sure the air is vented outdoors. Make sure all screens are cleared of lint.
Check the outdoor dryer vent seal to make sure it closes off the vent to the outdoors or your house will be leaking heat all the time.
Do use duct tape
It is OK to use duct tape to seal joints in the vent duct that are leaking air.
Clean the Heat Keeper lint screen after every laundry load. Twice a year move the lever on the Heat Keeper to match the season and make the functional checks again.
One more time: This is safe for electric clothes dryers ONLY. Clean all lint screens and traps before starting a new load of wt clothes, for efficiency and fire safety reasons.

Some building code inspectors do not like to see vent diverters, so you may have to take it with you when you sell your house.
On laundry day the smell of deterrent and fabric softener will penetrate the whole house. Some folks love the clean laundry smell. I don't like it much, likely a guy thing.
