Case study of 30 yr old fridge

In May 2009 we conducted an in-home case study. Sue and Ken Arthur from Cheltenham let AMDEA into their family home to measure the electricity consumption of their 30 year old fridge freezer for 3 weeks. This was then replaced by a new A++ rated model of an equivalent size and its electricity spend was monitored for the same period under similar usage conditions.

The dramatic results revealed that replacing an old fridge with an ultra efficient model can save as much as 80% energy; £137 a year in electricity; and recoup the cost of the new appliance in just 3 years.
