This is a four bedroom 3,800 sq foot detached built in 2000. The owner installed the Vortex in 2007 as oil was on the rise and their energy usage was also increasing. Prior to fitting the Vortex the owner was using 100 litres of oil per week on average and an annual purchase of 5,000 plus litres per year. Since fitting the Vortex this has decreased to between 3,900 and 4,105 over the last 2 years representing savings of approximately 25%. In addition to these fuel savings a troublesome radiator that needed bleeding almost every week has not been touched for 2 years.
