There is a lot of concern about cost on the part of the OP/daughter; have you looked at the monthly cost of running the proposed nine heaters? At 50% duty cycle at my rates it is $800/month. I'd be making sure you're not heating it any more than necessary and looking very closely at any "no energy" options. I personally know little about the subject or other options, just pointing out that electric heaters running outside are expensive!
