| dc.description.abstract | With rapid grotvth of population and urbanization, ihe energtt demand is increasing da1, by da1,.
Electrical energv is att important colnponent for devebping economlt" Only 40?1, of ou'
population has access to electricirl,^. Due to shortage in supply, it becomes important ta
conserv^e electrlcity. Although there is restriction to u,se electric heaters, still it is being ttsed in
sntall scale in halls, hostels, ruesses etc. Conventional electric heater losses lteat b.y radiatiott
throtrgh bottom and by concfuction through the mortar. Heating is not v-ery elJbciive, if tlte air
gap beht,een theutensils'bottom and coil plate is not optimized. A comprehensive studl'has
been conducted to improve lhe conyen.tional electric heater to redttce energy lo.gs. Heat lc'ss
through the bottom antl mortar is reduced by pfiting therntal insulation and a reflectfue
cauting. Tltree test specimens have been us'ed to carty out the test with an improvecl healer and
a conventional heater. The results reveal that energy cen be saved b,v :5%, 30?:o and l7l4 fit'
boiling tt;ater, cctoking rice ancl red lentil respectively. Also, alum.inurn sheet is tisecl instead of
white cement and thermal insulation to make the cctnstruction simplet' an-d the peibrnloilce test
has been caruied out. it i.s found that when glass u,ool with v:hite ceilxent is used, sove etterg) i,s
around 30o/t whereos the same is around 28'% when only aluminum sheet is used. Thtts, bv
