You want to explore the option of geothermal heat pump. During winter, your house needs a minimum heat transfer rate of 850 kJ/h (i.e., 850 k] of heat needs to be transferred into the house during one hour) to maintain a pleasant indoor temperature. You want to know what is the total electricity consumption (in kWh, assume from grid), if you run a geothermal heat pump with a COP of 5 for 4 months (24 hr/day, 30 days in a month) each year for 15 years. [Prompt #6] compare the use phase energy costs and GHG emissions between {his heat pump and a natural gas-red heater (85% efciency) [1019!]
