In the US it would depend on your climate, and whether you plan to install air ducts for A/C. When electric rates are high and you also need A/C, a high efficiency heat pump system is very effective, and newer models work in heat pump mode down to a relatively low temp before they go into backup electric resistance heat.

If your climate has very cold temps, you can also use a hybrid system, where it runs in heat pump mode most of the time, and the backup heat source is gas or propane. The initial cost of these systems is higher and more complex, but they give you high efficiency combined with the ability to handle low temperatures.

In some old house retrofit installations in the US they are using a mini-split heat pump with multiple "head units." You install one compressor outside, and 2-3 heads units inside, usually mounted high up on the wall. Since there is no ducting it makes the installation easier, but only works well if you have a relatively open floor plan that allows air to circulate to other rooms.

The one downside of heat pumps for many folks is that the air out if the vents does not feel very warm. Heat pumps usually circulate air all the time in heat mode, but it does not feet "hot" like you would get with an electric or gas furnace.

I suggest a close analysis of your fuel possibilities and their cost. It is my understanding that fuel costs in Europe can be quite expensive when compared to costs here in the United States. Mini split HP systems are more popular in Europe and have been slow to catch on in the states.

Thank you for your comments, we decided to update the insulation and go with electric. We could have gone with water or gas radiators but unfortunately very expensive. At least with the electric we can move them should we need to change the layout of a room and maybe one day we will add solar or wind power to our house
