We only have a holiday home out in France , but it's in the outback where it gets very cold.We managed to buy a second hand Franco Belge in the UK which is a French make (you may be able to search for there website). Anyway this was around £250.00 secondhand and pumps out 11.7 kw. From this we run 4 tripple rads up in the bedrooms , which are like toast. To control the heat you can first of all turn down the woodburner to cut of the air supply which gives a slower burn and of course less heat.The other method is to open the bedroom doors!! I would say that for us it is a much cheaper system , our loacl French builder did the complete installation (with header tank etc) incl the installation of the burner.So our total costs were around £2000.00 but now we only need to light a fire down stairs to heat the whole house. Hope this helps you , if you need further info let me know.
