18
500 ltrs solar hot water at Jabchok Chukha
19
Temperature for Thimphu From the above temperature it is imperative that heating is required
20
Solar Combi system Solar hot water and under floor heating system with Gas/electric back up system Rheau under floor pex pipe (water based system)
21
Challenges Longer pay back period ( Cheap electricity) Financial assistances Availability of cheaper solar heating systems Poor Plumbing solutions Poor energy efficient buildings Lack of Energy saving consciousness ( Mind set)
22
Opportunities Energy savings ( energy efficient constructions) Potential for more revenue from export of Electricity Harnessing Free Energy Promoting good Plumbing practises Increase in domestic revenue Employment & skilled manpower
23
Bhutan is blessed with natural resources White petrol ( Hydro potential) Green Petrol ( Renewable forest resources) Rich flora & Fauna, culture ( Tourism) Sunny Winters ( Rich in solar energy)
