The home I bought 6 years ago in Meredith has oil fired hot water/baseboard heat but I saw remnants of electric baseboard in all the rooms. The house was built in the late 80's when heating bills were high.
I was told by the realtor that the previous owner had to put in a "real" heating system when he went to refinance as electric baseboard heat didn't qualify as a "real" heating system?
Anyway, after I bought the place I replace the boiler and had an electrician come out and look at all the electrical. He found that the wires to the electric baseboards, which were just cut off at the floor, were still live 230V.
I'm still considering adding mini splits for AC and added back up for heat but right now it's pretty cheap to heat with oil.
