Out of curiosity I’ve decided to compare actual heating costs versus theoretical heating costs. The calculation shows how much it would cost If I used a modern conditioner instead of a centralized heating provided by city and fuelled by natural gas. Hence I crafted a simple Silverlight application using DevExpress Silverlight components (which helped a lot, but that’s another story).
The default data is my data for January but you can enter your own. While the application is in Slovene you can pretty much understand the huge difference just by looking at the chart below. So much for naively believing that heat provided directly by fire is the cheapest one.
