If you had a spare large pot with a tight lid, would it be worth it to fill it with water and let it get as hot as possible with any residual heat from the fire and let it just sit to cool slowly in an effort to keep the Abbey warm longer? I've always been amazed at how long my canning kettle exterior stays warm to the touch hours after I'm done. The lid is good enough that if it's not actively boiling, it doesn't add humidity to the kitchen.
Hello very nice this concept. Can you give some recent feedback about how Allerton Abbey do the job this winter with all these add on and up date *strawball wall, good door etc ) ?
Do you find i'ts a success ?
I just found this, and this is exactly what I am planning to build. I was calling it an earth sheltered greenhouse, I have never heard the term Wofati before. My modification would be a more traditional peaked roof with the southern half glazed, and the northern half under earth. I was thinking that on the northern side there would be clerestory windows for venting, and the southern wall would be fully walk-out. I am in the missouri Ozarks so I plan to use eastern red cedar logs "log cabin style" to form the stepped retaining walls. I was also figuring to line the back side of the cedar walls with old worn out barn tin to keep dirt from washing between the logs. I am hoping to achieve a totally passive freeze freegreenhouse. At worst I believe I will be able to raise hardy tems like lettuces and spinach etc through the winter.
