Monitor government recall lists. These lists are massive and they change daily. If you are interested, you can check www.cpsc.gov/recalls or www.recalls.gov for past recalls. 

The Oregon Department of Environmental Quality (DEQ) regulates the cleanup of underground heating oil spills and the removal of uncertified woodstoves upon the sale of homes. Woodstoves without an EPA sticker are deemed uncertified and must be removed when a home is sold. These stoves were typically sold before about 1991. 

Court ordered and manufacturer recalls for defective items such as roofing, siding, electric heaters, plumbing, etc. usually have an expiration date, beyond which the manufacturer is no longer obligated to make restitution. It is important to have a home inspector with enough local knowledge to identify these defective components that are still in use after the expiration of the recall.
