M69 Diesel Heater, Adjustable Power 12V All In One

I'm surprised how well it heats up. I use it in a 40 m2 garage and in an hour it heats up 4-5 degrees. At 1 liter of diesel at maximum power, it is capable of heating for less than 5 hours.

Works like it shud wow it’s hot in hear.It has changed our way of life on a boat. Install was easy, just figure out where you want to do it. Installed in the bilge of a boat so had to drill a hole and get a thru-hull exhaust fitting, but no big deal. The heat that this unit puts off though is amazing and being only 12v, it has freed up all the power we were using with the electric heaters that was consuming most of our 30amp 120v service. 15 degrees outside, it's a toasty 70 for us. We're in t-shirts and can look over and see our neighbors inside their boats in down jackets and hats. Can not recommend enough.

This unit produces a lot of heat, very decent quality but you'll need to do a few things to get it up and running to work properly for something like a tent.

This is an amazing little unit. Extremely impressed with the performance, fuel efficiency, and price.My only complaint is around the instruction manual same as most people have noted. If you are somewhat mechanically capable and watch the multitude of YouTube videos you will not have an issue. I installed mine in a Pelican Box for Truckbed camping. Just finished two weekend trips in North and South Dakota. Temp in the teens and Ran it over 8 hrs. on lowest setting. Nice and toasty inside and only used about 1/3 tank.

Works great. It just needed a few extra parts to make it work well.
