I have noticed there are a few installers who request the elctricity account ot determine the equipment size.
I dont get it, if you use 15 kwh or 30 kwh per day how do you determine the equipment size?
One site has aircons running through the might and another has a home exec washing and very little power in the evening, both site use the same amount of kwh.
Anyone know how or why a person would use the elctricity account to size equipment ?
