Abstract
This paper investigates the suitability of sewage source gas engine heat pump (SSGEHP) as a retrofit application for a public shower facility. The system performance is evaluated by primary energy ratio (PER) based on a practical example. The performance analysis indicates that the PER of SSGEHP varied in the range of 1.4 to 1.9, showing good potential in primary energy saving (as high as 69%) and emissions reduction compared to gas boiler system. It only needs 1.6 years to recover the initial investment by using the SSGEHP water heating system to reform existing the gas boiler. Therefore, the SSGEHP may be a promising retrofit scheme for the existing gas boilers.
