'High efficiency natural gas heaters' generally have a slightly higher heat conversion efficiency than 'high efficiency oil heaters', so there's not much margin in a conversion in Europe if high prices only last a year or so.

Top efficiency for oil furnaces is currently around 86.6% AFUE, so these models don’t have the higher 98.5% efficiencies that are available with natural gas furnaces. - carrier.com

Electric furnaces are considered to be 100% efficient, but that number is deceiving due to the low (about 30%) efficiency of producing the electricity, as well as transmission loss in electric lines.
