It really depends on a lot of factors. For example if you have solar, how well insulated your house is, etc.

I am currently renovating a house in Germany and had a quote for a heat pump system and a quote for a central gas heating system. The heat pump system was quoted at 66.000€, it would however be reduced by 24.750€ to 41.250€ as the government is currently giving a subsidy for these systems. The Gas system was quoted at around 18.000€.

Both of the quotes included removing the old Oil Heating system and disposing of it. The Gas System included the price of connecting to the cities gas supply.

I went with the Gas System, as not only the install would be cheaper, the running cost would also be substantially cheaper. Some electricity providers have a seperate tariff for heat pumps that is marginally cheaper. However even then my calculation was that a Heat Pump would only have a comparable running cost if I also invested in a large Solar install on the Roof.
