Reasons for choosing ThermoJoy - costs and amortisations
Point 1 on the X-axis of the chart shows the purchase costs of the various types of heating systems. The slopes of the coloured lines represent the annual operating costs for each system (energy used and maintenance).
The table shows the purchase, energy and maintenance costs of the various heating solutions. The amortisation is calculated as the ratio between the excess investment and the annual expenses to be recovered. The excess investment is calculated as the difference between this system and one that costs less. The annual recovered expenses are calculated as the difference in operating costs compared to one with higher costs. The years of cost benefits are calculated as the difference between the years of life and the years of amortisation.
