There are huge differences between the various types of equipment available and how much energy they each consume, which causes it to be very confusing. The Electrolux range we supply clearly states on their specification sheets how much water, electricity, and gas each load consumes on their washers and dryers. Many other manufacturers claim to be extremely efficient but do not publish these figures… Our advice would be to ask for the published consumption figures, if these cannot be provided, it makes proof of these efficiency claims very difficult.
