Portable Heater ..elect (watts/amps) big buddy or catalitic?

This probably should be in a couple of posts but I think it may all be relivant. 07 Allegro Bay 35' chevy... brand new LCD 32" Samsung TV & Dish 211K reciever, sometimes Sony Blue Ray player.

I have in the past used my RV heater when plugged in. I boondocked (Quartzsite & BLM land)
a week and used it to knock off the chill before bed on generator and got up once in the night and ran it for 1/2 hr or so no generator. and then in the a.m. for 1/2 hr or so no generator 7 couple times during the day again no generator. I ran the generator every
evening for a 2-3 hours and watched TV and charged up batteries. I plan on doing more boondocking this next year... 2 wks at Q, 1 wk at SLABS, a week at a time here n there maybe 8-10 more weeks in between RV parks w/hookups)Wally world one niters traveling.

I know there are some plug in thing that tells me how my batteries
are but don't know what it is or what to buy.. it plugs into the dc outlet by tv(not the cig lighter by the steering wheel) (someone told me not to do that as I have a power antenna booster thing and it could effect it).

My monitor pannel has 6 lights up and down. In the morning I
checked it and it was 2 lights down so I had 4 lights left but don't know if that means 65% still left in batteries (I have 2 house 6v) again been told like holding tanks this is not reliable. I have never had more than one light down that I can remember.

What I use on boondocking... frig on propane. so not much there,
I have LED bulbs in the 3 lights I use and only use one of them at a time maybe 1/2 hr
after generator is off.

I wanted to find out what heaters you use when plugged in to a/c and when boondocking? the propane ones say you have to leave windows open.. how open and do they turn on/off. I do just fine at 50-55, but it droppped into the 35-40 range last year. What about those 12v lap blankets?

Also, thinking about adding some type of solar to cover the TV issue and charge up batteries. BUT. I can't climb up on roof to raise the pannels.. I also don't want to spend $2000-$3000. Oohh boyt That opens up a biggie question.

On elect heater in general.. they are 750/1500 watts low/high. Will my wiring and plugs in my RV handle the heater on high?

Also, told because I have 50 amps in RV.. some of my outlets are on one circuit and some are on the other circuit & I should get some tester to find out which are which...

Sorry I'm an old grandma and not to electrical savy. Although I'm a quick study.. sometimes.

Whew...Sorry for so long winded. but wanted to explain.

  • The fan in a standard heater causes most of the "issues" when dry camping. I have no idea if newer RV furnaces are those "98% efficient" type (plastic stovepipe) but the only heater I could ever live with while dry camping was an Olympian Wave Heater. Otherwise I burned so much fuel for heat and electricity I might as well have gone and parked in an RV park. Some folks wanted to take me by the shoulders and shake and yell "You can't do that (use a non vented catalyst heater for 20 years)". They're dead now.
  • direct propane heat is the most cost effective and 'distribution' effective

    the propane furnace will heat the 'whole' RV, the furnace intake and exhaust connect outside, it is a sealed system just like a HOUSE

    it uses battery power for the blower,
    but MUCH LESS power than your electric heater is using
    electric heat via inverter from battery is costly, NOT efficient and hard on the batteries

    a Catalytic heater plumbed into the RV propane system is extremely efficient and cost effective
    ours is in the kitchen, i crack the kitchen ceiling vent and one kitchen window
    to provide for fresh air ventilation when the Cat heater is on
  • Hi,

    Unless the outlets are upgraded it is best to keep loads on them to less than 800 to 1000 watts. I have replaced all but two of mine.

    When on shore power or running a generator, my favorite electric heaters are 1/2 size oil filled units that draw 464 watts each. I keep one in each corner of the bedroom. I have another "flat panel" oil filled heater for under the dinette.

    Solar costs are about $2.00 per watt for parts and materials. It would be best to start another thread about solar systems.

    Really the only truly safe catalytic heater is the Platinum Cat because it is vented. It is also thermostatically controlled so you can keep the RV at a comfortable temperature.

    Whew, lotta questions. I'll try these...

    I'd likely use a 1kw electric heater on shore, however, if it dips below freezing at night, my furnace and only my furnace is on at 55. My furnace heats the basement pipes.

    No, I don't leave any windows open when running the furnace. However, my main furnace ducts are not in my bedroom. Only when it gets really cold will I need bedroom furnace heat, and definitely not with open windows. I don't have bottomless propane.

    12v blankets of any kind are usually very ineffective. I've found a 120v mattress heater to work great, but you need 4 batteries and a good inverter.

    Cheers
