Stand-up heating?

For my 2.2 TiD would cost such an offer 336,- net, i.e. with tax about 390,- the part incl. installation. I think that is a pleasant price, the question is only whether it is worth it. After I am currently unfortunately lantern parker, this would probably be a fine thing in a few weeks already. Does this thing also heat the engine? That would be almost more important to me than a warm interior, seat heating has ic But I’m afraid in winter my ~15km drive to work isn’t really enough to bring it to temperature. What have you done with the heater? P.S. Had a 9-3 convertible 1.8t in the Vector equipment as a rental car today. Inside I find the current 9-3 very nice, also from the front this is really a great car, only from the side and the rear… but it’s great, only the engine was not optimal in my opinion.
