Just guessing but maybe heat pumps have a lower max power rating, so that you'd need better insulation to reach a desired temperature during colder days.
It's better to use heat pumps.
yes, that's correct, but heat pumps do much better than that, as explained downthread
This trope is getting tired, heat pumps exist.
Heat pumps are far more efficient than resistive heating, so this wouldn't be economical.
You probably want heat pumps instead for heating...
If I understand correctly, it's the lack of a heat pump.
Electric heat pumps are quite efficient, AFAIK.
It's not even correct. It's much more efficient to use a heat pump.
The explanation of needing to pre-heat the air into the heat pump is strange. Modern A/C systems can pump heat at 500%+ efficiency even with very cold outside temperatures, no pre-heating needed. Replacing that with resistances is a 5x or more reduction in efficiency. That heat pump doesn't seem to have an outside unit so may be less efficient but it would need to be very poor to go down to only 100%. Installing a proper A/C system would provide both much higher efficiency heating
