I bought it because it was advertised as 8 kW, but in reality it delivers only about 3.5 kW. This was confirmed by Vevor themselves, who admitted the 8 kW claim is mainly a marketing label. Unfortunately, 3.5 kW is not sufficient to heat the space I intended. Here is their response Dear customer, Thank you for being so patient. Kindly note at 0.36 L/h fuel consumption and ~9.8 kWh/L, the heater can only receive about 3.5 kW of chemical energy. With realistic efficiency (80–90%), the actual heat output is ~2.8–3.2 kW, not 8 kW. The advertised “8 kW” for this type of diesel air heater is not a measured thermal output. It is a nominal/marketing rating or size class, often referring to a theoretical maximum or product category rather than real delivered heat. In practice, many low-cost “8 kW” diesel heaters deliver around 3–4 kW of usable heat, which aligns with your energy-balance calculation. Detailed efficiency or standardized test documentation explaining the 8 kW claim is typically not provided for these products. If you have any more questions, please don't hesitate to contact us.

It was installed in an annex room. From here we had an outside connection for the exhaust pipe. From this annex we made an entrance to the main room for the hot air. CO2 increased above 1500 ppm.

Pessimo prodotto. Rumorosissimo fuma. Assolutamente da sconsigliare. Impossibile contattare servizio assistenza che quando risponde (tramite mail) risponde con risposte a caso. Di fatto sono 10 giorni che cerco di avere il reso ma sbatto contro un muro di gomma. Delusissimo.
