3.41 BTU per watt for resistive heating. Heat pump gives you way more heat per watt. That is why most of the electric cars have gone to heat pumps for the heater. The heat pump Tesla will run the heater for 36 hours and still leave you with enough battery to get home in many cases.

Off grid home The $800 mini-splits I am looking at put out about 6K BTU's of heat on 400 Watts. The home depot $300 heaters put out 5K BTU's but require 1500 watts.. Not going to do well in the winter overnight off grid... And no a/c in the summer... On 1/20/22 5:53 AM, Jan-GAMs wrote: $1895? For a one room ac/heater? Home Depot has something similar for $300. Is it the decal? Hood ornament?

This one is in the sunbelt of N. Nevada and currently I have 4K of solar feeding a 30KW LFP battery bank through currently a Victron charge controller and a couple midnight solar inverters to generate a flawed 220 as well as two sides of 110. ( the 220 will not run the well controller even though supposedly configured for such. ) I am upgrading the inverters and controller to a https://www.signaturesolar.com/products/8kw-48v-240vac-split-phase-120a-250vdc-off-grid-inverter-by-growatt planning on doing a couple 9K mini-splits for heating/cooling. I wonder if this group has some gotchas that I might learn from in advance before I buy myself into a corner...
