Ana:
 
 
Best reference I've ever come across (with example calcs) which mimics the approach of E+ as I understand it can be found here:
 
http://apps1.eere.energy.gov/buildings/publications/pdfs/building_america/44816.pdf
 
See page 22 (of 49) for the inlet mains equation, alonog with a plot of Chicago IL TMY2 results so you can Q/A your implementation of Equation 4 (correct placement of parenthesis in this makes a BIG difference)
 
All the Best,
 
_Chris

Hello everyone,
 
I am trying to model  domestic water heaters and need to estimate entering water temperature. Is there any database or procedure that I can use to estimate this value? I am doing  spreadsheet calcs using hourly output. I would appreciate your suggestions and advice. 
 
Thanks
 
Ana
