    This unit works great, I have about 10 000 hours on mine without the slightest problem. I was not really expecting it to work so well but I am completely satisfied with it. I can’t see why anyone would purchase the more expensive brands. I noticed the cheaper Chinese knockoffs are adding the name to their key words so it comes up in searches, don’t fall for it. Planar makes quality heaters.

    I don’t have one of these but I am considering buying one for my boat.

    I am discouraged though when I see one review and the person claims, “I have about 10 000 hours on mine without the slightest problem”. 10.000 hours, really?

    • Planar Heaters Customer Support

      Hello Eric,
      Thank you for the interest in Planar Marine & Truck Air Heaters. One of our clients even managed to use one of our diesel heaters for more than 15,000 hours! When you’re looking into hours, 10,000 hours is a little bit more than a year. A client of ours is using his planar diesel heater for almost 3 years all season long. If you have further questions, please do not hesitate to contact us.
