When the Pfeiffers’ made this beautiful pavilion, they wanted their guest to be able to enjoy the space year round and not be cold. To accomplish this, we provided Infratech Heaters thoughout the pavilion. These heaters evenly keep warm people as they enjoy their visit. These are an Infra-red heat which will warm objects, not the air. This leaves you very comfortable while enjoying your wine in the pavilion. For other Infratech products, please go to their website: http://infratech-usa.com/. These heaters work wonderful in outdoor residential gathering places as well.
