Hi,
I am comparing 13-sheer (11.18 EER, 2.25 COP) with 19-sheer (14.06 EER, 2.63 COP) Residential type heat pump unit, All other parameter (Envelop, Glass, Lighting) are same.
ECB show only 10 % saving in Energy wise and 6 % saving in Cost wise.
I feel that its too low.
Is there any idea how much we expect with this comparison. Any suggestion will be Appreciated.
Thank you
Anil Bhari
