Abstract
REVISED MARCH 2013 The Building America (BAPIRC) team at FSEC has released a report containing results from a second testing rotation (Phase II) on seven hot water systems evaluated side-by side. Results show the seasonal performance variation and compares solar systems against electric resistance and the Heat Pump Water Heater (HPWH). Standard and tankless natural gas were also evaluated, where the latter demonstrated a 24% natural gas reduction. The lowest averaged electric power consumptions were demonstrated by the HPWH (2.75 kWh/day) and the PV-pumped solar water heater (3.03 kWh/day). Other testing performed on the HPWH under conditioned and restricted air space (93 ft3) simulating a closet, resulted in a 14.3% increase of electric use and a 12.8% in COP reduction.
