1. Phase out Electric Shower Unit Water Heater Accounting Environmental Friendly Compact Heat Pump or Hot Water Solar Collector as Renewable Energy for Substitution of the Electric Shower Unit Water Heater in Domestic Sectors and Resort Hotel Prince of Songkla University,Thailand APEC forum: Energy Proposing APEC economy: Thailand Co-sponsoring economies: USA and China Expected start date: 1 January 2015 Expected completion date: 30 December 2015 Fund SourceAPEC Support Project Overseer:Dr.Twarath Sutabutr. Assistant: Dr.Kuaanan Techato

2. ESU: 3-5 kW 3,800 kWh/year HSC: 2 m 2 20 W pump, 1.25 kW heater (0 kW if off grid), 150 L efficiency 43.8-52.6% (100-530 kWh/year) CHP: 0.78-1.25 kW, 300 L storage, COP 4.2-5.5 (300-800 kWh/year) Rationale: Phase out ESU to CHP or HSC RE – cleaner energy In line with APEC to reduce intensity 45% by 2023, free trade, and green growth

3. Hot water Load Curve in Household Energy consumption 500,000 ESU/year x 3kW difference to CHP or HSC or 1500 MW

4. Project Objectives 1 Create a frame work of phasing out for electric shower unit water heater for using in economies 2 Enhance understanding the feasibility of substitution 3 Build interest from consumers, designers, contractors, regulators, and manufacturers

5. Outcome The installation of 500,000 electric shower unit water heaters would be substituted by either 0.5 kW heat pump or 0 kW of hot water solar collector or about 1,500 MW per year Well-known standard is used for performance testing to be good for consumers comparison and fair play among manufacturers for free trade

6. Budget 120,000 USD  Traveling7,500 (3 seminars)  Labor40,000 (6 man-years)  Hosting 22,500 (3 seminars)  Publication20,000 (3 seminars)  Other10,000 (10% university)  Self funding from pilot case participant 20,000 USD

7. Alignment Align to Vision Statement of EWG: Achieves greater energy security through the use of a wide variety of energy sources that are developed in a safe, efficient and environmentally sustainable manner Align to Mission Statement: Endeavouring to double the share of renewables in the APEC primary energy mix by 2030, and increasing the number and type of renewable energy projects Align to Deliverables: Develop Cleaner Energy Sources: APEC Member Economies meet their energy needs in a way that minimizes impact on the environment and is safer for future generations
