water = (Mixed temp. – Cold) divided by (Hot temp. – Cold) This style water heater will have one or two electric, heating elements immersed located low in the tank; a second element is commonly located down about 1/3 of the tank height from the top of the tank. These elements will seldom
This water heater must be installed and serviced by a qualified person. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months.
Residential electric water heater(s) shall be a self-cleaning Energy Smart model control logic that shuts down all electricity to the heating elements in the event of no water or low water levels in the tank. The water heater shall have a self-diagnostic control that monitors
Temperatures skidded so sharply this weekend that Chicago felt like Alaska — only colder. The high temperature Saturday topped out at 65 degrees, demolishing the old record of 69 degrees set more than 30 years ago, according to the National Weather Service. The high temperature didn’t even reach the average low of 68 degrees expected for Chicago in late July. A slight recovery Sunday pushed the
