Ultraheat Tank Heater AC/DC

[TECMike]

Looking at possibly installing an Ultraheat 40 gallon tank heater with dual elements, both AC and DC, which would allow the tank to be heated while traveling.

Sure would appreciate hearing from those who have installed this tank heater. Was the DC mode too much current draw for your tow vehicle and converter on your trailer/fifth wheel?

Would you buy this model again or buy just the model for AC only and use it when plugged into shore power?

Thanks in advance for your comments.

It would appear you are changing the subject.

Does anyone with propane hot water tanks just run it on propane while travelling? That would seem to be a lot more straightforward then using battery power. Is it dangerous?

My mistake Don, They are listed at 13.5v but now I see the 40 gal heater does show the 12v draw at 9 amps.

Whew, with one for each of my tanks it would take the 8-D to make it thru the night. Luckily the size I need is only 4.1a draw, that I can manage.

Hi Jim,

They are available as 12 and 120 volt or as just 120 volt. In a three season trailer where the temperature is going to stay below freezing it would be wise to have the 12/120 volt version so tanks could be kept warm while traveling.

I saw the ad for them in another thread and noticed the DC voltage was 13.5v. Fine if you have shore power but if you did why would you run it off of DC?

No, the tanks are not enclosed. It is a three season trailer.

Hi,

If you go for the dc option you may need to beef up the charging path from the alternator. Are your tanks enclosed?
