I think there are large room diy heat pumps. "diy mini split heat" found me this [0] for example. Also, depending on your hackerness, you could adapt window air conditioners. From what I've seen, solar PV for heat only really makes sense if you're using a heat pump. But solar thermal for heat can be good, though. http://builditsolar.com has a number of DIY heating projects for X,000 USD in materials.
