RV comfort cheap heat "don't buy"

The first winter great 2013, last winter 2015 it stopped working replaced heating coil fuse Larry sent it free still under warranty. Paid to get it fixed. 2015 This year it's stopped twice paid to fix it once last time today I won't do it again.
Larry is a great guy but mine is a lemon.
It heats great when working....

Have you checked for high/low voltage at the parks you stayed at? Could be a reason the fuse is blowing ?

?

I agree, low voltage causes higher amperage draw, which does not bother resistance heaters, but will melt fuses.

And high voltage can melt resistance elements.

I use space heaters. I modified the RV to run 'em (Installed a pair of proper 15/20 amp outlets each fed with genuine 12ga wire each from a circuit breaker that powers ONLY that outlet, one 15 amp one 20) Standard RV wiring is not up to 1500 watt heaters long term.

I'm currently in S.E. GA where it hit 35 last night here (30 offically but 35 was my lowest) and I used only 2250 watts 750 in the living room (Thermostat added over last 2 days but it is still on as I type) and 1500 in bedroom.. Got a bit cool here. but, as it happens, I like cool when I'm sleeping. I could have 2 or 3 more heaters in storage if I need 'em.

Average cost per heater is in the 20-25 range (The 750 watt "Fireplace" was I think 30 before I added the Thermostat, Which was about 30 as well) (Nice Honeywell LINE VOLTAGE Thermostat, This unit is NOT affected by power flowing through it or by the heat of the heater so it works real well) So replacement is simple and low cost when they fail.. Most last several years. Oh and the 750 Watt. Standard RV wiring is more than up to that.. But watch out for chained outlets (only one to a breaker folks)

Lower voltage will not increase the amount of amps drawn with a resistance heating element. Think of a regular light bulb. If you lower the voltage the bulb gets dimmer, but it's not drawing more amps. Basic Ohms law.

I have a progressive industries EMS-PT50C it checks for low or high
it would kick of before it affected the RV.

The guy decided to refund my money good man.

Except bulbs resistance changes with illumination level. I have some 1000 watt bulbs that have a cold resistance of one (1) ohm. The dimmer that they are on limits the inrush current at ten (10) amps. Once they start to glow the current goes way down.
