We primarily use Bunn Commercial Coffee Brewers. They are excellent, durable machines and we stand by them. We have pour-over brewers  where you pour your own water into the coffee machine just like you would at home,  and we  have in-line brewers that can be hooked in to your water line. These brewers have  1-3 warmers and some have a hot water faucet for tea, hot chocolate, oatmeal, etc.
