My trailer is wired for 30 amps. My TT would not be able to run this option.
Your missing the fact that a gas furnace is only 60% eff (that a documented fact) plus the electric heater has no pre purge or post purge. So.......... when you measure the true sensible heat out of the register over a one hour period (BTU's an Hour) you get about 18,000 out of 40,000 gas.
That being said (17,500 Btu's) 5000 watts = 21.7 amps per leg on a 50 amp service (which is actually a 230 VAC service). This is not much more than my two roof top AC's use during the summer.
Readers Digest version I have it installed in my 5th Wheel, Its cheaper to operate than gas and keeps the RV much more comfortable. Lastly I spent some time in Maryland where it was as low as one degree outside and the cheap heat system did a wonderful job, nice and toasty 72 inside WITH OUT ANY GAS.
Oh ya and there is no cold air coming out of the registers because there is no pre purge or post purge, Fan on Heat on-- Fan off Heat off.
But as you said if you only have a 30 amp service it won't work for you unless you upgrade to a 50 amp service (rvcomfortsystems.com have upgrade documents).
For those of you donít have one and that think its BS donít buy one, but please donít talk smack to the people that have it and like it.
