goede prijs kwaliteit, helaas zonder thermostaat, want zelfs op 0 graden blijft het draaien. onhandige display, met rare gebruiksaanwijzing. maar warmt op en niet duur.

While the unit over is pretty nice and does work it is no where near an 8K heater whether you are measuring input or output. An 8K heater should produce (or consume depending how it is rated) approximately 27,000 btu per hour. I was heating with an adjustable propane heater with three level at 15,000 btu, 30,000 btu, and 45,000 btu. Generally I use the 30 or 45 setting to heat the room up and then kick it down to the 15 to maintain temperature. Generally even the 15 setting is too much and I have to cycle it on and off every 30 minutes or so. I though this heater would be perfect as I could run it on high to heat the room then scale it back to maintain temp. However, on high this raised my room temp about 2 degrees per hour. On low (15,000 btu) my propane heater raises it about 4 degrees per hour. So next step was to look at the fuel consumption. They claim .36 liter per hour and diesel has an energy density of 35,000-36,500 btu per liter. This equates to 13,140 btu per hour at best. Considering there is a heat exchanger with external combustion the efficiency of this unit is probably 80-90%. Once again going on the best case this leaves us with it being close to a 11,800 btu heater or a 3.5K heater.

Habe das Gerät ausgewählt, weil es laut Beschreibung Räume mit 20qm heizen kann. Leider kommt aus dem Gebläse nur mäßig warme Luft in der Standardstufe 3 (weniger heiß als ein Fön). 5 Stufen hat das Gerät. Bei Stufe 5 wird es etwas besser, aber dann produziert das Gerät schon einen Höllenlärm. Also wie eine Turbine. Mit Stufe 3 braucht es mindestens 1 Stunde bis der Raum spürbar (5-10 Grad) wärmer wird. Ausgangstemperatur war um die 3 Grad. Nach einer Stunde vielleicht 10 Grad. Der Dieselverbrauch ist tatsächlich gering. Leistung auch. Geräusche nicht.

I ordered 2 as a backup, and 2 as running units. The two running units stopped working within 3 weeks.

Well I got to use the heater three times before it wouldn't ignite anymore and after breaking the control panel realize that you can't even buy a new one for it. So I had to buy a new unit which now is working and works great compared to the last one. But I also discovered that your last one the wiring was underrated to run it

The unit worked great for about two months and now won't even turn on. Would be great if the motherboard wasn't right on top of the burnchamber

It took 3 diesel heaters before this last one finally worked. What would have cost $250 ish to install via a diesel mechanic ended up costing me over $1200.00 total. Vevor wanted me to make sure my oil and oil filter was clean. It took a lot of going around in circles with customer service to fully reimburse me each time for a product that would not start/light at all, even though fuel was getting to it. The only other product like it is 3-5k which is significantly more and rumor has it they have problems too. Maybe not out of the box though? So I’m happy to announce the third one works and so far so good. It’s only been 2 weeks. It’s great to finally have heat on a cold winters night in the Utah desert. Fingers crossed. Good luck to you all.

Helaas was hij stuk na een keer gebruiken daarna meteen een storing

Ne fonctionne pas totalement niveau thermostat Il est impossible à régler Exemple demande de 16 degrés au thermostat Chauffe en continu et ne s'arrête jamais de chauffer Chaleur insoutenable quand on rentre dans la pièce malheureusement j'ai 28 degrés dans ma pièce ce qui est beaucoup trop Si il fonctionnerait correctement je suis certain que ça serait un top produit.....

There is so much work in installing this, that I got a propane heater instead.
