Sounds like a good thing to have, but Winter is on the way out now and with all the grill blocking I warm up within 2 miles on the coldest days. I'm thinking more about an on demand heat exhaust fan for the engine bay;Possibly routed through the unused air intake in the reverse direction.
I'm expecting to receive mine in a couple of days. Can't wait.
Just have to order a few liters of coolant and start mounting. I have the technical possibility to connect it also at work! Have to ask my boss (will do after I mounted it) but I don't expect problems.
I will start a new thread when I receive mine and will post pics of the mounting.
As I live in Belgium I know I don't really need the thing, but I want to experiment with it for the fun and the MPG !
Wintertemps in Belgium are typically a few weeks freezing when daylight and a some more weeks also freezing at night. 'Freezing'....: -1 to -5?C.
Best you don't know yet: car is parked in garage (garage in house on top of it). That's why also connecting at work would be very convenient. There I always start with a colder engine than at home.
I voted I do but I just realized that I don't... I have a dipstick heater. (no trouble with cooked oil, but I only use it sub 20 degrees F.) For me it's not so much mileage as it is getting the little beast to start at 5am, and -10 degrees. The winter's been mild so far, but January and February are usually brutal.
I'd rather have a block heater... but I think this Subie may be going on to... well something other than regular duty, so I doubt it'll get one.
Now since I'm in the process of shopping for a new (to me) car... well, well, well... you better believe it'll be getting a heater of some kind. Especially since I found out that the outlets downstairs are on the Landlords meter (sssshhh, don't tell anyone).
