For electric hot water heaters use column "A", for Gas use column "B", click on the next box down after each entry.   A   B
1. What is your water bill this month? $ ______ (A)    
       
2. How many gallons of water consumed this month? _____ (B)    
Note: Your monthly water bill (A) (divided by) your total gallons        
of water consumed (B) will give you the cost of water per gallon ©    
       
3. What is your sewage bill this month? $ _____ (D)    
Note: Your monthly sewage bill (D) (divided by) your total gallons        
of water consumed (B) will give you the cost of your sewage per gallon (E)    
       
5. What is your [(i) Electric / (ii) Gas] bill this month? $____ (G)    
6. What is your [KwH / BTU] consumption this month? ______(H) ( example: 2.9 BTU = 2,900,000 )    
* Question 5 and 6 will depend on the dropdown list chosen from question #4        
Note: Your monthly kWh/BTU (i / ii) (divided by) your total kWh/BTU used will give you the cost of your kWH/BTU (I/J).        
       
For Electricity (i):        
- *It takes 0.13958 kWh to heat 1 gallon of water from 50F to 120F.        
- The length of shower ( #11)(multiplied by) (Q or R) = The number of gallons used (K),        
The number of gallons used (K) (multiplied by) 0.13958 kWh = How much it cost you to        
heat the water for the length of your shower (L), (L) (multiply by) The cost of your kWh (I)        
= What it would cost to heat the amount of gallons used in your shower (M).        
For Gas (ii):        
- *It takes 890 BTU’s to heat 1 gallon of water from 50F to 120F.        
- The length of shower ( #11)(multiplied by) (Q or R) = The number of gallons used (N),        
The number of gallons used (N) (multiplied by) 890 BTU = How much it cost you to heat        
the water for the length of your shower (O), (O) (multiply by) The cost of your BTU (J) =        
What it would cost to heat the amount of gallons used in your shower (P).        
       
7. How old are your existing shower heads?        
(a)Installed before 1992 Typically 5.0 gpm (Q)    
(b)Installed after 1992 Typically 2.5 gpm (R)
