SOLAR WAll OVEN
Frequently asked questions answered.
A large capacity, reflectorless, slant face solar box cooker designed to be installed for access through a tunnel in a south-facing wall in your home.
The convenience of solar cooking without having to go outdoors, saving time and effort, plus avoidance of cold, hot or windy weather. You can bake food in summer without baking yourself. Windproof. Dustproof. Insect proof. Dog proof. Rainproof.
Wrong question! The right one is; "how much food will it cook?" Answer: an entire meal for a family - bread, main dish, veggies, dessert, side dish and hot beverage, for example. If you really need to know the cooking temperature (with a fairly heavy load in the oven) is typically 250 deg F summer, 220 deg F winter.
Yes - two loaves at a time. And cookies to - two large trays fit on the oven floor.
It has a large glass area with internal reflectors, giving it a wide angle of sunlight acceptance. It cooks most effectively from 9AM to 3PM. 10:AM to 2:PM in winter.
It does a good job collecting diffuse light, high thin overcast light, and cloud edge effect light since it accepts light from many directions. It often can cook when other types of solar cookers fail.
Spring, summer and fall are best. Of more limited use in winter (you can't bake bread), but still usable for many cooking purposes for smaller amounts of food.
Sure. It's weatherproof, so it can remain outdoors year in and year out. By rotating it to catch morning and evening sun you can get it to cook all day long. The low heavy Solar Wall Oven did not overturn in a gale that removed some of our sheet metal roofing.
We've experimented with that and found a 3-panel design that gives excellent results in the dead of winter. Info will be found in the Do-It-Yourself Guidelines. A reflector of some sort probably would be needed beyond 45 degrees latitude to collect low angle light.
Barbara Kerr's prefers the Solar Wall Oven to any other type of solar cooker, and uses it far more often than any of the many others in her possession. Beginning in 1985 she installed and tested eight Thru-The-Wall designs. The present Solar Wall Oven worked the best. The one mounted in Barbara's home has been in has been in operation since 1994.
Pasteurization (using a "WAPI" -
water pasteurization indicator.)

The hoped for production version has not come to pass. You will have to build one from Do-It-Yourself Guidelines
Use the instructions provided in the the Do-It-Yourself Guidelines. It is readily adaptable to conventional frame, straw bale, cob, adobe, papercrete, cindercrete, rammed earth, cinder block, stone or what have you.
You will be spending several hundred dollars or more for all new materials, and less if you can salvage materials.
No detailed plans exist. Only the Do-It-Yourself Guidelines are available.
