Unclear. We just got solar panels and are auditing all the energy users now. There were some resistive heaters running we didn’t know about that pushed an extra 500kWh before. I think we got it down to about 1600 kWh. I think with all the he mods we are doing we can get it down below 1000 kWh but it will take time and more efficiency improving.
I would suggest to get a smart electricity meter so you can see "live" power usage. I'm not familiar with resistive heaters, but it appears they are purely electrical, which means they are only 100% efficient. Heat pumps (you can use AC for heating) are >300% efficient.
For reference: my 2 person household uses less than 3000 kWh / year (gas heating and electrical cooking), so even 1000 kWh / month would be a lot imo.
The solar system provides a whole house real time meter so we should be able to track down usage easier. We’ll see. We have two teenagers and a larger house and workshop, so, quite a few variables to figure out. We are converting the whole house to heat pumps. These units are state of the art and hit 370% efficiency.
We have a boiler and some resistive heating. We are going with whole house (6500 sqft total) heat pump system. Ends up being several large commercial Fujitsu units that are efficient down to -20F (Colorado weather). We expect to dramatically cut our energy consumption with this move and be totally off natural gas. Combined with the solar and battery system we are getting we should be completely energy independent and net producing electricity which is cool :)
