I wrote about my experience about 2yrs ago, see http://electric-vehicle-discussion-list.413529.n4.nabble.com/Resistive-heater-core-access-for-S-10-conversion-EVA-kit-tips-tricks-tp4680519p4680524.html
The two links on that archived post are still good. The canEV heater is offered in different configurations (from low to high voltage packs), and the other link is for high voltage pack designs. What type of heater and what wattage you will need is more than just the EV's cab size as there are other factors to consider. -I was happy with the 1.6+kW hair drier type, though it took a while to do the job. Today's hair driers are rated at 1875 Watts, see https://www.target.com/p/conair-174-salon-series-midsize-turbo-dryer/-/A-10878193?lnk=rec|adaptpdph1|related_prods_vv|adaptpdph1|10878193|0 But later, complaints from the under-dressed gal I wanted with me gave me motivation to throw money at her issues by using the S-10 heater core that was still there, heated by a (now defunct) Russco heater. It drew 120V 25A off a 132VDC pack. So, family considerations is also a factor in your heater wattage decision (if she refuses to wear more clothes, you will need more heat). -At the time, my S-10 Blazer had 6+ chargers on-board (a 22+kW charging ability) which let me push my range way out further than any conversion in my area had gone. When I was down in SoCal (Los Angeles) area, I didn't need the heater even in the dead of their winter. It wasn't until traveling back north on the I-5 grapevine, that I saw some people with snow purposely piled on their cars. I took a side trip from Lebec, CA to Frazier Park. I was glad I had the much more powerful Russco heater (it was colder than this CA boy liked). So, if it snows where you live or travel, that is a factor in your heater wattage decision. -A similar (heater saves the day) experience happened nearer to my SF Bay area without any snow. I was pushing my Monterey, CA trip range-envelope by leveraging off a Marina Dunes RV park. When while charging, it began to rain. Then rain really hard (like the way it does near an ocean coast). The windshield fogged up to the point of condensation on the inside of the cab. I did not bother to use the heater until the charge was near completed. Just before I was ready to leave, I used the heater to dry out the windshield. Even with that 3kW heater it took a while, but I would not have been able to drive (or see out the windshield) if I had only had the original cheaper hair drier type heater. So, how much moisture you will have to contend with is also a factor to consider. IMO, it is better to have 3000+ Watts of heater, same as I feel it is best to have the most charging ability you can (j1772 L2-6kW & L3 if possible). You may not use all of that capability the majority of the time, but when you really need it, it is there to do the job and save the day :-) For EVLN EV-newswire posts use: http://evdl.org/archive/ {brucedp.neocities.org} -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
