| Abstract | Electricity was considered as the most common energy source of residential homes in the Philippines. With the country's expanding economy and population, energy consumption is also increasing, which results in shortages that often cause a rotating brown-out, particularly during summer or dry season. Second to the highest electricity consumption by households in the country is from water heating and one of the biggest energy consumers in residential homes and in commercial buildings is the electric resistance water heater (ERWH) which is generally used in showers and sinks. One replacement for an ERWH is the heat pump water heater (HPWH). Heat pump is a device that transfers thermal energy from one location to another, like air conditioners and refrigerators, which can achieve higher efficiencies. However, HPWH units have been available for several years but have experienced minimal success in the marketplace, especially in tropical countries like the Philippines, due to lack of awareness and knowledge of the technology among consumers and few case studies to validate the technology. This research aims to evaluate the potential of a HPWH as a water heating alternative in residential and commercial buildings like hotels by calculating the required heating capacity in providing hot water for bathroom use. The heat pump unit used as basis in this study had a coefficient of performance (COP) of3.8. Hence, factors that were taken into consideration for the computations are the water temperature entering the tank, number of people in a household, the hotel's occupancy rate and number of guests staying in a room, and the time of operation per day. Results revealed that as the inlet water temperature decreases, the overall heating capacity increases. This is due to temperature difference whereas lower inlet water temperature leads to higher change in temperature, thus, requiring more heat to be transferred. The overall heating capacity was used to evaluate the simple payba |
