This thread talks about some heating options. Really like the Dickinson.

Refrigerator use is more variable. Some of the older models used up to .75 amps 24/7 and some of the newer ones as little as .35 amps and then only when the burner is operating. Some have fans, some do not. The factor fan takes way too much power, in the range of 0.4-0.5 amps, but replacement fans can take as little as .02 amps. So, generalizing about the total amp hours is very difficult.

The electronic ignition water heater also takes 12 volt power when the burner is operating, but none when it is not. I don't have the amp use at my fingertips, I will have to look it up. But it is not a large user overall.

I just try to use the water pump only when I must...every bit of battery power saved matters, is my logic.

If I run water with the pump to wash and rinse the coffee pot and a few dishes in the morning, I can use that same water to empty the toilet during the day....minus the pump running and fresh water being used from my finite supply.

I don't have a gauge that tells me when every bit of battery usage occurs, and how much, and I am glad as I think I would drown in the minutia of it.

Amp Usage

Maybe this will be useful:

The range lights can be replaced with LED for about a 90% savings.

The refer number is without the cooling fan running, just the logic board and ignition circuit.

These are from actual amp readings in my 25 footer.

The running lights are for the trailer only and do not include a tow vehicle. (Mine are switched so I can turn them on when unhooked. Good light for connecting hoses and cables in the dark.)

Fantastic fans are on the highest setting.

The pump monitor is the MicroPulse unit.

The under cabinet, shower and bath lights are both halves on. The 0.14 amps is when using only half the fixture.

Item Amps Furnace 7.60
Refrigerator 0.78
Water Pump 8.70
Pump Monitor 0.06
Bathroom & Shower Fans 1.20
Fantastic Fans 3.00
Lights Main Overhead (High) 1.53
Main Overhead (Low) 0.31
Bedroom Overhead (High) 0.56
Bedroom Overhead (Low) 0.12
Reader Spotlights 0.16
Under Cabinet, Shower, Bath (ea) 0.27
Above at 50% 0.14
Range Light 1.71
Step Light 0.06
Patio Light 0.11
Running Lights 1.20
Range Fan 2.11
TV Antenna Booster 0.07
Stereo (Clock Display Only) 0.74

Cheers

Amp Usage and an unrelated heating solution

A bit more information: On the overhead lights, each puck draws about 0.14 amps on the high dimmer setting and 0.04 amps on the low dimmer setting. The numbers I previously provided were for a 25' and I realized that each trailer might have more or less of the pucks installed.

If your thermostat is like mine, it is capable of handling more than one zone. You can install a temperature sensor in the area where your pipes are most likely to freeze (like in the area just below the floor where the water lines pass to the basement) and then set the temps for that area down to about 50F or less, if you thermostat will allow. Leave your furnace on but then heat the living area with whatever options you choose. Your thermostat, if properly set, will be monitoring the temps in the basement and kick on when it needs to. If you thermostat isn't capable of zones, you can pick one up at Lowes or Home Depot that will. Just be sure it can include the heat pump if you have that option and want to use it.

We are full-timers but if we are not using the water pump, hot water heater they are turned off. The habit is instilled in us so it works for us. We put a lot of gray water in the black tank. I think that helps the tank.

Everyone has to find their own comfort zone. I am comfortable turning things off when not in use.

Good points on electrical usage, or lack there of with the pump.

But I would just add in regard to the water pump it is a good idea to shut it off when you are out. For other reasons.

I have lasted 7 nites living in a venue parking lot in Chicago in July. No hookups, no need for water heater, i read via ipad at night, wash a couple things in morning. But I am working and really using Bambi for sleep, shower and foid orep. It works great foe me and I have battery to spare. I do use a battery fan at night that I top off during that day at my booth. I put led lights in, too tired to do much at night.

Idroba, there is an LED that lights when the pump is on. It's maybe 2 mA, and consumes 0.12 Ahr out of potentially 50 Ahr of usable battery capacity. So if you leave it on for 24 hours you've consumed about 0.12*24 = 2.88 AHr, or 5.7% of the usable battery capacity.

My calculations in my previous post were nonsense. 2 mA is .002 AHr, so 24 hours equals .048 AHr which amounts to less an 0.1% of the usable capacity! It's insignificant!

Thanks for realizing your error and posting your second response. And your second response is quite correct.

Nice thread, I hope more folks read it. Might help folks to understand why their batteries are dead, seems those have become a rampant subject.

Radio? I think it runs about one amp.
TV?
Inverter = serious power users, switch to smaller cigarette lighter type, might reduce the overhead of a bigger system.
