    Satisfied with my purchase

    Posted by Carlos on 6th Dec 2018

    Minus 1 star because paid for 24-48hr shipping and it arrived a day late. Other than that works perfect with my parksmart unit after i figured out that this unit has an internal fuelpump so i had to remove my external fuel pump setup for it to work

    I have had Eberspacher heaters on a canal boat.installed correctly and serviced annually they will go just fine. Heatso/Reddmann service was very good
