As the cost of electricity continues to increase, consumers are looking for new ideas to help get the most of their appliances. This includes electric dryer.
Although consumption can not be reduced, there is an apparatus to take advantage of the heat it produces. It is called a dry heat recycler. It has proved to be a winner in the struggle to be more energy efficient.
A heat circulator does exactly what the name indicates. It lets the warm air from the households electric tumble dryer be redirected back to the laundry room. This is an added bonus if the laundry room is in a cold basement. Plus the heat is free.
The theory behind the reuse is simple. It uses the hot air from the electric dryer to heat the laundry room. This way the room valve can be shut down. Then you lower the heating costs.
The element in an electric dryer is approximately 5000 watts. This corresponds to a pair of baseboard heaters. The temperature in the air leaving an electric dryer is about 130 degrees Fahrenheit. So why waste it - instead, put it to work for you.
For an investment of about $ 15 the hot air your wiper normally dumps outside can be steered back into the house. We have successfully suggested these to customers for years.
There is a plastic handle on the side to direct the air either inside or outside. During the winter months, the handle is adjusted to direct warm air into the house. In the summer the air is directed outwards.
The heat recovery device is easy to install. It is usually fitted (screws are fitted) to a wall or a beam behind, and slightly above the dryer console area. Once installed, the drying valve can be cut and attached to the unit. Follow the instructions to maintain proper airflow direction. The recycler has an in and an out. Always install the recycler for easy access by all family members. If installed in an inconvenient location, nobody will clean the filter.
Before purchasing, ensure that the model you purchase comes complete with two ventilating clips. Some cheaper does not include the clips. Clips are important for proper installation. Do not be tempted to attach the ventilation sections to the recycling unit with duct tape. It dries out and causes the ventilation to fall off. If necessary invest in two high quality metal valves. A couple of four inch clamps cost about three dollars.
The recycling unit has a built-in filter screen that needs cleaning just like the one in the dryer. We prefer the type that has a network screen filter as opposed to it with a sock-like filter. Its a few dollars more but the metal filter is durable and much easier to clean than the cotton type.
As soon as the recorder is mounted and secured, it gives the test run. Set the temperature selector to the hot and starter dryer. Allow the dryer to go for a few minutes. Test that the air enters when the handle is in winter mode. Then hold the handle to summer position. Air should be seen as walking outdoors. Go out and confirm that the air is free to fly outdoors. If not, the screen in the outlet valve may be blocked with ribbon. Or the valve valve may be fixed. Return indoors and try all air leakage leads. About leaky air, tape joints with channel tape.
From then on, all that is required to clean the heat recovery filter is every pair of laundry loads. Plus, turn the handle twice to redirect airflow. Not much work to get all the nice hot air to your home.
Please note that throughout this article I have used the term electric dryer. The heat recovery machine can not be used with a gas dryer. The ventilation pipe for a gas dryer may not be opened or redirected. Small amounts of gas vapor and carbon monoxide may be present in the exhaust air in a gas drier. For safety reasons, therefore, the heat recovery machine can not be used with a gas dryer.
TECHNICAL TIPS: Experience has taught us that we do not mount the reuse directly above the dryers starter switch. This avoids the recycling that gives you a blast of hot air on the face every time the dryer is started.
