I just did some heater testing on my bench, and there is no way that the ceramic heater running at 96 volts will do much for my EV. Based upon that, I will not be using a ceramic heater, but instead a 1500 watt water heater and pump through the existing core.
What I did was compare my AC ceramic heater to my DC version. I found that the AC heater had a "warm heat" range of about 2-3 feet, and there is about 4 feet of ventilation. Figuring the resistance of the heater element and my battery pack voltage, I would get a max of about 650 watts, which would do about nothing and get "lost" through the ducts.
I am looking to use a Kat's 1500 watt block heater and I am still looking for a hot water pump.
