Dear Dr. Brew,

I have heard that I should not use water from my hot water faucet, i.e. from the household water heater line, but should always use the cold water line as a source. Is that due to temperature, quality, or something else? Does not the BUNN keep and hold hot water pretty much as a house water heater would? Thanks for any info.



Dear Ken,

I have heard the same information concerning the use of water from a water heater system.
A home water heater is usualy set at 140°F or lower. A commercial and some home brewers maintain a ready to brew temperature of 195 - 205°F. A water heater system is held at supply line pressure hwere a coffee brewer is vented to atmosphere.

I went to the EPA web site to ask for information and received the following.

Recently you requested personal assistance from our on-line support center. Below is a summary of your request and our response. Thank you for allowing us to be of service to you.

Each manufacture generally states in the installation manual, whether the equipment should be plumbed to a cold (tap) water supply or hot water (with a specified maximum temperature) supply.
Also review all supplied literature for water filtration systems.

Happy Brewing,
Dr. Brew
