Electric Heating while at the Dock
Posted: Wed Dec 16, 2009 12:17 pm
Howdy boys. It's been a while. I have been neglecting the boat for a bit. I guess my question stems from that. I want to extend the usage of my boat, at least the cabin space, into the winter. I have two breakers that run the A/C sitting at 15A each (I think). I have four empty slots on that line for expansion. Do you think I can draw enough juice to have effective heating in the main cabin and sleeping quarters?
You can check my math:
I have 2X30A lines from the dock, one of which powers the A/C, so basically I have 30A to play with.
I was thinking of using these:

or these:
http://www.heatersplus.com/gfr.htm
They are fairly compact and I can adjust the output. (If the breakers start blowing)
The high setting is 1500W at 120V, (I=P/E) =12.5A
I know that it is rated at 30A but can I expect the breakers to withstand a 25A draw? Will two, be enough in Maryland?
Am I re-inventing the wheel? Anybody got a better idea?
Thanks,
Eric
