A garage is being retrofitted with a heat pump of COP=3. The garage heat losses are 10,000 BTU/h. How much would it cost to heat for one month (30 days) if electricity costs $0.14/kWh? How much will it cost to heat with an electrical baseboard (assume 100% efficiency)? Ans: heat pump - around $100 (exactly $98.5); electrical baseboard - $295.40

Question 2. A household with electric resistance heating plans to switch from resistive heating to a ground source heat pump. Annual heat consumption of the house is 30 000 kWh. Investment cost of the heat pump is 21 000 €. Heat pumps COP is 4.0. How much are the annual savings compared to resistive heating after the change of the heating system (in kWh)? Average price of electricity is assumed to be 12 c/kWh. Round off your answer to one decimal digit and enter it without the unit.
If a house needs a minimum heat transfer rate of 75 kJ/h (i.e., 75 kJ of heat needs to be transferred into the house during one hour) to maintain a pleasant indoor temperature. If one wants to use a heat pump with a COP of 5.55 to fulfill this heat transfer rate, what is the corresponding electricity (in kWh) consumption to run such a heat pump for one hour?
