Block heater - choices?

really. .... guess our Toyota OEM block heater must have been a reject because it would make our Prius ICE warm in just 1 hour.

.

 

I find one hour gets you a leg up (maybe 10~15C about ambient), two hours to where it plateaus (about 20~25C above ambient).

I'd be inclined to stick with the stock block heater, but I'm not that adventuresome. I can't recall any Prius c block heater installs reported here; wonder if it's the usual PITA?

There were some concerns about 4th gen block heaters, believe it was their power cords were defective. Not sure if that would apply to Prius c though.

Does block heater show as an accessory if you go to Toyota site and "build" one? I think it does up here: you could try the Canadian site, see what the installed accessory cost would be. That may only be appicable with new purchase though, not sure. The part alone is around $70~80?

 

Looks like maybe some of us here ought to check out the priuschat chat store, just a couple clicks away.

I don't know, you could always install a 240 to 120v Step Down Transformer.

I do miss using the 240v teapot I had during school years in Cambridge UK. Much more efficient

May or may not be compatible with Prius c. Probably is, but worth checking. Someone recently ordered that block heater through PriusChat Shop, but had a LOT of problems with delivery. Can't recall the outcome now, I think they ultimately managed to just stop payment, weren't getting any response from PriusChat Shop.

 

I have tried aftermarket heaters from zero-start and Katz. both would not fit due to the size/shape of the part next to the cord. I am assuming the Toyota part works, but didn't want to spend the cash and order one to try.
