The author seems totally unaware of the efficiency gains that a heat pump can provide. A 300W space heater will be easily outmatched by a heat pump that consumes 300W (unless we're dropping way, way below 0C). The efficiency is likely ~3x [1]. I hope the author isn't making this mistake out of disdain for centralized hvac, since window unit heat pumps are readily available for small spaces.

- jqm 12y agoI found this out the hard way one winter. Without looking into specifics I decided that a couple of small well placed space heaters (in rooms with traffic) might save electricity over the whole house heat pump. I had 3 small space heaters that ran most of the day and night and I turned the heat pump down to 50. I was wrong. My electric bill was higher than just running the heat pump, and most of the house was cold most of the time.
- Retric 12y agoHe is dealing with -30 below winters at which point most heat pumps are almost useless. A ground source heat pump can still be useful but they cost quite a bit more to install so they might not be worth it if your to far north.
