Vevor 8kw Portable Diesel Heater Review | All In One Diesel Heater, Is It Worth It? 

Good information, thanks!

@@Myksgarage ​ ​ Some pointers for you. The air hoses supplied can be stretched to full length. They are supplied compressed for ease of transportation/packing. You cannot extend your exhaust much but you already have the maximum allowed bends in your video. The silencer should be fitted with the weep-hole at the bottom, to allow any condensation to drain from the hole. They appear to be efficient because the heat output is far less than you think you are getting! It is certainly not capable of the advertised output claimed. More efficient operation would be where the cold air, for warming, is taken from inside the heated area. Yours is safer, as you pointed out, having it outdoors. Your battery does not need to be of large capacity if connected to a battery charger, which would run the heater after the starting sequence. A battery charger with ‘float’ mode would be best. You only need a larger battery if operating away from the grid or during longer grid failures. The battery is necessary for the final shut-down sequence, to avoid overheating the motherboard and possibly killing it. They are very good, if installed safely. Again, extending the warm air hose has limits. Too long will restrict the warm air throughput (and also the combustion air, leading to sooting in the heater casing). A good video on the installation. Well done.

Good suggestion!

That's pretty good

@@Myksgarage It cannot deliver 8kW. Doubtful even anywhere near 5kW. One tank-full, of 5 litres contains only around 53kWh of heat energy (maybe as much as 55kWh). With 80% efficiency, there is only 44kWh of warm air available, so the tank-full should only last 5 1/2 hours. If it lasts 8 hours without even draining the tank it is likely only about 5kW, or less. Actual specification of maximum fuel delivery per hour would indicate output. Many quote 0.51l/h, which would be 4.3kW, but lots do not feed at a pumping rate to deliver more than about 0.46l/hr which is even less output. Less than 4kW What is the real specification of your heater (not the advertising lies from the manufacturer)?

It could probably do 500-750square feet

@@Myksgarage IYO, could you extend the exhaust pipe to provide additional radiant heat?

Thanks for the info!

Yeah that would be best

read @oliver90owner, he suggests putting the air intake inside your heated space, but keep the burner outside to reduce sound of the pump and eliminate exhaust leaks from the heater unit being inside your space.

🤷

Yes!!

Does the heater recharge the battery during use?

@@paulhart7739 no, the heater runs off of a 12v power source ( battery or 12v power supply) it does not have a wall outlet.
