Depending on other factors in the building's envelope and which mini split you choose you probably don't need any backup heat. What is the zip code where you live? We can use that to find temp averages to determine the winter design temp. Don't trust an electrician for HVAC advice. In fact you probably don't want to trust most HVAC contractors for HVAC advice. You need to find a very well informed HERS rater or something like that to get the straight dope on all of this. I can tell you this right now though, you are trying to heat a very small space and if it's insulated and air sealed marginally well just about any minisplit on the market will give you heat on cold days.

You know you're an ecorenovator if anything worth insulating is worth superinsulating.
