When using a heat pump VARIO system, what is the money saving in contrast to an oil burner system used for heating and hot water production?

The operating cost of an installation depends on many miscellaneous factors, such as the country area, the heat insulation of the building, windows etc. Additionally, for reducing the operating cost is very important to make the correct choice concerning the capacity of the heat pump. This way the unit will use the whole operating energy of the Inverter compressor and the low cost energy consumption that can be achieved in certain circumstances. By approximate calculations the operating cost saving in reference to the oil price, is about 40%. This percentage may be higher if the installation is based on each residence and its needs and of course if the correct system has been chosen.
