>it's been awhile since I've been in this group.
>curious, is there a generic operating cost calculator - heat pump versus fossil
fuel - that allows you to adjust you HP cut-off setting based on current fuel
prices (electric compared against gas/oil/propane)
>I found this, but it's an Excel file and formulated against a particular brand
of equipment; also the efficiencies are a bit low to todays' standards.

>maybe I'll just have to tweak it and rerite it for WWW access with mySQL
database for table storage, but I'm really too busy (maybe too lazy) to attempt
it now - many customers of heat pump with gas furnace installations are
requesting this "tool" especially those purchasing Carrier's Infinity systems.
