Jamjas1 year ago000Doesn't it need a lot of electricity to keep the water warm? I'm not familiar with it... and does it make noise during the keep warm function?

After 6 hours without use, the appliance switches off automatically.Show in original language (German)Commentleuenbea1 year ago000The keep warm function is noiseless. A coffee machine and a TV also need electricity.Show in original language (German)Comment1 comment
