In pursue of energy-efficient alternative water heating options, a SWOT-AHP analysis was accomplished for Solar Water Heater (SWH) and Heat Pumps (HP) against instantaneous water heaters (IWH). The results show that the energy consumption and bills saving are dominant in strength of both HP and SWH. Financial and technological aspects seem to play a relatively significant role. Additionally, HP and SWH are more convenient for the energy consumption in water heating technology in hotel sector of Thailand. Finally, we can say that HP and SWH are more convenient for water heating system as compare to IWH.


Keywords –Water heating, Instant water heaters, Heat pump, Solar water heater and SWOT-AHP analysis.
