Please read the entire profile. This is an oil boiler (for hot water only) from Chofu Seisakusho. The screws for attaching the remote control are missing. The remote control displayed "888" due to being 10 years old. (It is unknown whether "888" will appear again if reinstalled.) It was still usable, but I replaced it with a new model. Some water may remain inside. There is no warranty, guarantee, original box, or instruction manual. Errors may appear on the remote control due to potential malfunctions when moved. Please only purchase if you are okay with it being broken, can repair it yourself, or need it for parts. - Brand: CHOFU Thank you for viewing.
