Some in­ter­est­ing so­lar facts

Business Day - Home Front - - HOMEFRONT -

Test re­sults from pi­lot stud­ies have shown that en­ergy sav­ings without a timer or load man­age­ment de­vice av­er­aged about 44%. The in­tro­duc­tion of a timer im­proved en­ergy sav­ings to about 66%. Where no elec­tri­cal back-up is in­stalled, all the elec­tric­ity pre­vi­ously used for wa­ter heat­ing will be saved, but with a greater risk of oc­ca­sion­ally hav­ing cold wa­ter.

To op­ti­mise en­ergy and hot wa­ter sav­ings, in­stall en­ergy and wa­ter sav­ing shower heads to re­duce hot wa­ter con­sump­tion.

In­su­late hot wa­ter pip­ing to min­imise heat losses and re­duce the re­quire­ment for elec­tri­cal backup power.

Sav­ings can fur­ther be max­imised by us­ing hot wa­ter in the evening rather than in the morn­ing, for ex­am­ple by show­er­ing or bathing be­fore go­ing to bed rather than af­ter get­ting up.

Show­er­ing gen­er­ally con­sumes less wa­ter than bathing.
