No. With heat pumps electricity is way cheaper for heating.
Only on nights with temperatures below -5 Celsius gas is cheaper.
The problem is that most vendors are sold out.

With larger apartment complexes it may be economically feasible to pursue geothermal heat. In this case a more efficient solution could be a heating arrangement using hydronic heating combining geothermal heat, waste heat, topped off with an efficient large-scale boiler (the apartments need hot water anyway), and then pumped into radiators or underfloor heating.
And naturally the most efficient solution of all could be district heating.
