Patent number: 4476921Abstract: Low grade heat is supplied to heat air which is used to provide an insulating sheath for a building or the like. The low grade heat is obtained from the ground below the hard frost line from either air or water, or from solar collectors, biomass or any other suitable source of such heat, and is used to heat air which is then circulated in a space within the walls of the building, thereby maintaining the internal temperature within the walls at approximately 45.degree.-65.degree.
