Answer to Question 1

In many boilers the return water is mixed with the supply water to maintain a temperature of at least140F returning to the boiler to reduce the chance of reaching the dew point in the boiler flue gases.

Answer to Question 2

False. Electrical shock can be just as likely to happen when working on a low voltage system if you come in contact with a conductor.

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
