I will keep an eye on it now that I'm recording the info.

So, if I figured this on the back of a napkin...

That would be about 2 days and you've used about 5.07 Kwh in that time,
so that would be about 2.535 kwh per day. I don't know where you live, but just guessing that the rate might be maybe $0.22 per kwh, that would figure out to about $16.73 per month. I don't know how that compares to the LPG consumed... pretty much depends on your local market.

And you have some cooler weather ahead, which will make the costs go up and you'll surely do some optimizing, which would make the cost go down.

I'm really interested to see how it all pencils out over time.

Best,
