Heated moist air comes into the box through a flexible aluminum pipe attached to the duct and exits through the filter into the room. This is the existing flex and rigid pipe as removed from the dryer after re-attachment to the bottom duct of the heat recovery box instead of to the outside vent. Normally this would be vented outside or clogged in the outlet pipe. This easily built project recovers warm moist air from a clothes dryer that would otherwise be exhausted to the sub-zero outside. How do you get gloss paint off your clothes? To paint a pergola for lasting protection, it is important to follow the traditional procedures such as preparing the surface which include removing old paint, using sandpaper to permit absorption and applying preservative towards the end of the painting. Done as before by removing the spit from the bbq and moving it to a shady area to measure.
Installation involved removing the existing aluminum flex hose from the wall and attaching it to the duct on the bottom of the box. The box has a plywood back and is attached to the wall above the dryer with two wood screws. Here are two approaches: one by Gary Reysa at builditsolar and another by ALK Engineering. With one load at full heat with -15C outside, the moisture from the clothes dryer dissipates throughout the house and does not normally condense on the cold window. This seemingly simple protective clothing can save you a lot of time in the laundry room and save you from tossing out your good clothes. If the shadow is within about 5cm of the dowel, this is good enough. If the shadow is small and falls almost directly near the dowel, the aim is good and the sun’s concentration achieved is about 18 times. Aiming disk. The shadow of the small dowel on the disk shows less than perfect alignment and gives an indication of which way the bbq should be turned in order to point more directly at the sun.
It would not be effective, for example to thread the hot dogs onto the spit through their radial center as opposed to lengthwise, through their axial center even though it might seem to increase the capacity of the bbq (more hot dogs cooked at once?). I have attached a small plate with a captured nut the same as on the bottom of cameras (1/4-20) so I attach the bbq to the stand with one screw, the regular one used to attach a camera to the stand. One of the dogs after about 25 minutes. We have put a strip of aluminum foil over the bottom third (it is not very smooth) to see if it was more reflective than the aluminum roof flashing (if dogs heat quicker over the foil) and possibly to catch any drips. Using flexible mirror in place of the roof flashing might double cost but improve performance, probably near double (will cook faster and hotter). I will use a mirror film shortly and start cooking earlier in the day.
With the aluminum roll flashing as the reflector, I estimate about 200 watts of cooking power available. Two things weren’t perfect: I’d started cooking in the late afternoon, at about 4pm as the sun was already part way down the sky. Look for compact versions for just one or two people. Energy is saved two ways: heat used to dry clothes remains in the house and less cold air is drawn in by preventing negative pressure. Electrical energy that is used to dry clothes contributes to house warming. Moisture that is added to the house air is welcome during a northern winter when the cold temperature outside causes the air in the house to become very dry. Another benefit of the project is to effectively seal up this leak to the outside for the winter. 6000 watts. When I do use it, it is good to know that the expensive heat is used twice by not being blown outside. I only use this in winter. I also have a indoor clothes line which is used on damp days and even in the winter.
I use the outdoor clothes line whenever possible. My clothes dryer is used as little as possible as it uses an enormous amount of electrical energy. If you spill something wipe it up and soak it up as quickly as possible and then flush with water and soak it up with a towel, or what ever you have at the time. I then filled the existing exhaust hole through the wall with fiberglass insulation. 3) Before starting to apply the texture, do not forget to take out any wall paper. Trying again today with four dogs and starting mid-day. The dogs were warm to the touch and mouth though and already cooked (according to the package). You should also ensure it does not come into contact with your eyes or mouth. There should be one and half inches of play room. I can tell if I have excess moisture easily when I see condensation on the windows in the same room. You can buy commercial heat recovery units at the Home Centers like this one from Jafine. I made a simple box of scrap wood with a slot in one side to insert and remove a standard furnace air filter.
