| Without wanting to hijack this thread from MPG,- just a few follow up comments.
These heaters are heavy duty and designed for diesel trucks and construction / farm equipment too. The user reviews were encouraging.
I could only estimate the possible fuel saving and it may not justify the expense for those living in moderate BC areas.
Increased passenger comfort in winter and reducing engine wear are also factors. For most cold winter places, these heaters could be of interest and value. |
