If you have an existing Electric Boiler that relies on the electricity to heat water you probably find it expensive.  Essentially these giant kettles draw on a lot of energy and can account for up to 50% of your TOTAL electricity bill!   Imagine an average 2 person house in Spain with an Endesa bill of €100 per month could slash that by up to €40 simply by retrofitting our Green e-Pack to your existing configuration.
