electric heater

Many camp grounds I go to have shore power. As the weather gets colder I plan to continue camping but don't want to use my furnace unless it becomes necessary. Why use my propane if I am already paying for electric?

So my question is how big of an electric heater do I need to keep my 5er comfortable? Don't need 75 - 80 degrees, 68 would be fine during the day. I am talking about an 08 32 foot Rockwood Signature Ultra-lite 8280SS. Nothing real big and needs to be able to run on 15 amp circuit. I see the ceramic heaters seem to be popular. Weight is a consideration. Would like something that will work even when it gets to 15 degrees outside and understand I might need to run two at those temperatures. I am sure there are members that do this so am looking for suggestions.

Jim

In sizing you need to consider what else may be on that same 15 amp circuit. A 1500 watt heater draws 12.5 amps in itself when on 120 volt power supplies.

The way you can do the amp math is watts = volts x amps

Or amps = watts divided by volts

1500 watt heater = 120 volts x 12.5 amps.

Basically if you kind of know your square footage then buy your heater accordingly and staying within the amp rating. Ceramic heaters are the best. I use a small Ceramic heater in our 35 ft camper and are temps are around 40 or so and it keeps it bearable. Later RJD

Trust me I understand all that. What I want to know is how big of a heater, or heaters, do I need? What do members use that have worked well for them? There are only 15 million different ones to chose from out there, LOL. Sense it is just the dog and I, I will know what is plugged into the circuits.

I have two small Honeywell(16x6x6), just $30 guys from Walmart. They don't have perfect thermostat just a rang of heat that you kind of get to know. For us one works good in the day or over kill to heat the bathroom for a shower, at night we use two because our bunk house is on the opposite side of the camper.
We like it cold though, 54-ish at night, 72 to get up and get dressed and 68-ish in the day and we're happy campers. We have never camped at temps below 24F at night, normal cold for us is 45.

We have the Eden pure 1200 watt heater works great a little expensive but originally got for another purpose. We do like the fact that the outside surface does not get hot, since we now use it camping would not want anything else.

I use the 1500 watt heater on our fireplace and ad a second 1500 watt in the bedroom when needed to heat our 42' fiver. Stays fairly comfortable and if really cold will turn the furnace on to help.

What a timely question, the grass this morning had a white sugar coating and felt kind of crunchy - no kidding .
We use a Presto Heat Dish (Costco many years ago) with infinite temp. settings and tip over protection.

I have to add that the heatpump on the AC is our first choice as long as the temps are above freezing. This morning it raised the temperature from 15 C to 22 C in under 15 minutes - I was impressed since the outside temperature was only + 1 C but the sun was out.
Sorry, to lazy to convert

We found the secret to using electric heaters is to run them on the low heat setting...they last a long long time that way.....and don t get hot for potential hazard...
usually one is enough and supplement with camper heat....but sometimes two are required on low heat in 5 er....one upstair and one down...on two different circuits...
they seem to draw around 7-8 amps on low each....well within the 15/30 amp limit so you can still use micro or coffee pot without tripping a breaker....there again common sense applies which the human race has, but doesn t use most of the time.
