Question

Assigned Problem A homeowner in Chicago ahs determined he wants to install a heat pump after watching a Sierra Club special on Channel 11 where they explained how energy efficient heat pumps were in a house in California that is located close to L.A. Using the above graph with its 80,000 btu design heat loss, and 3 ton heat pump unit, select a back up furnace to heat the house when the heat pump can't do it any longer, and select what the backup heat form will be ......gas, or electric Hint: To determine the least expensive form of heat, simply take the heat content of the energy source (3113 btu per Kw for electric, 100,000 btu per therm for gas) and divide it into the cost per unit of energy ($.14 for Kw electricity and $.50 per therm of gas). The resulting numbers will be quite small (your calculating $ per BTU after all) and just simply take the least expensive. Show your work below, and turn in to your instructor for credit. How big of a back up furnace will you install? At what temperature will you disable the heat pump and simply run back up heat? What fuel source will you use for back up heta?
