Ok, I'm /definitely/ getting a ceramic heater tonight from Walmart. Probably a tall lasko, whatever they have.
I was crunching the numbers and even though it seems silly to run an electric heater off a 16% efficient generator when burning fuel directly(propane) is 100% efficient, I started doing some energy calculations and found out that...
1 gallon of gas = 6000-7000 wh of electric energy.
1 pound of propane = 6600 wh
1 gallon of gas is $1.89 here, 1 pound of propane is $1.43. (And, if you do what I've done, it's actually $3/pound since I've been purchasing the coleman pound canisters with an intent to refill.). I buy gas anyway for the generator, and cold snaps here only seem to really affect the RV early in the morning and late at night,
(Also forgot to mention, I sealed up 80% of the holes In the wood that makes up the bench (Seems custom built, not quite sealed.). Now my legs don't feel like they're freezing, lol. I obviously need to seal up the rest of the RV to maximize heat conservation. I also need to seal off this "other room".)
Additional benefit of electric over propane: No CO! I was using my CO meter and found that the use of the propane heater increased the CO level by 15-25 ppm to somewhere around 25 ppm according to my kidde CO meter. The "Danger danger" threshold is 30ppm.
They warned in the package about how it affects cardiovascular patients and, yes, I've definitely noticed an uptick in those events recently. I suspected it was the 'cold' that was causing it, but I'm now strongly suspecting the CO levels have something to do with it. CO is not exactly a gas that people, or any animal for that matter, naturally breaths in the wild.
I would've really liked to buy a dedicated vented propane RV furnace or some such, but the cost of the furnace didn't seem to be justified with how often I should really need heat here. It seems like "really cold days" only happen about 20 days out of the year, here. I personally don't think 55H/45L as a "really cold day", it's easily tolerable without a heater. I'm thinking more like 45H/30L or below. The extra expense in gasoline seems like a rather minor cost.
Anyway, I thought it was funny they market these propane converters as "Vent free"... but, IMO, what the hell? Yes sir, I find the breathing in of combustion byproducts so worth it! lol. I guess it's "easier to install", but holy crap, I'm not that freaking lazy for that to be a compelling side benefit. Cut out a hole and caulk it up, right? Anyway, it seems like 'vented furnaces' tend to be rarer, but I think that's just because they're more expensive than the vent-free crap ($500 vs $60). I personally think the Mr.Buddy Heater is only really usable in the outdoors, or if you make the indoors effectively like the outdoors - Open all the windows and doors during use, lol. (I opened all the windows, but the PPM still climbed to 25 regardless.)
AND... I'm going to see if I can retrieve my mail tomorrow from the local post office. They didn't send it to the regional distribution center, despite my delivery at 1 PM and they obviously didn't scan it in ("Oh, I'm going to have to scan all those in" he moaned... lol... HE OBVIOUSLY DIDN'T! lol). That just not going to fly for christmas shipments. Maybe it's OK with ordinary shipments, but definitely not ones with critical tight deadlines. I have $2000 running on this and I just can't afford to refund everyone because of the slothfulness at the nearby post office.
Anyway, it's a good thing I started sending things out today, so I could identify weaknesses early so I can correct them in a timely manner. Not quite why I was originally sending things out early (I just wanted to get things moving out of my RV. I also wanted to avoid overloading myself at the last minute, should that cause me to miss deadlines.)... but a good thing to identify early nonetheless.
I still need to find the location of the regional USPS processing center. Google doesn't seem to be helping. I'm hoping it's taped to the PO boxes in front of the post offices and I'll find it there, tonight. And, if I can't find it, I'll ask tomorrow when I'm getting my packages back. Usually they have later deadlines, which would be extremely useful for me right now.
AND... I never knew how much a laser printer used until today. It crashed my 2000w inverter like four times, and hooking it directly upto the generator caused the generator to go "Vrooom! put, put, put... VROOOM!..." over and over again, lol. It's clear the laser printer was asking a weebit much of it, lol. The printer actually worked (It printed out papers properly), so I assume there's nothing wrong with it and that's just its normal nature. Laser printers use tons of power.
And, I've also properly shielded my generator so that the neighbors down the street can't hear it. Especially the trigger-happy guy with the gun. So, hopefully I shouldn't get too many complaints/visits from them.
(And, actually... I can probably use it during earlier/later hours. Will probably be useful tomorrow.)
