I suspect the diffence here is what we pay for electricity. It is quite expensive in Europe. I pay around 0,35 euro per 1 kWh.
For me the savings on the electrical bill will be more than what I spent on the machine before the warranty is over.
A newer machine however is a lot more efficient when looking at your energy and water bill.
Switching from an older to a newer machine made quite a difference on my monthly bills.
Based on the text in your image i assume that you live in the Netherlands. I would advise you to discuss this with your employer. As you are unable to plan a needed psychiatric appointment during working hours you have the right to take some short leave time for that.
