Sorry for my late reply * I was off-line *
Sure: The case is that I dislike the start of ice-cold diesel engines. I usually have a Webasto heater in my cars. Very convenient! I usually install it myself. But it*s an 8-hour job to install the heater. I don*t have the time (or the garage) now. So I was looking for a simple solution to warm the engine.
A found this one. It has an in line circulation pump. Very simple and a 90 minutes install job. The install is just to cut the hose to cabin heater, mount the heater and arrange the cable to the front bumper. If you put clamps on the hoses you don*t have to drain the coolant fluid.
9 out 10 times when I want it heated the car is in the drive way next to a power outlet. I have a phone/timer-controlled switch on the outlet. 60-90 minutes of heating makes a nice warm engine to start. A couple of minutes after start the car it*s fully defrosted. I*m pretty happy with it for now.
Also cheaper with a couple of Kwh instead of 0,4 l fuel to run the Webasto for 30 min *
