The EVGTTI 12V 8KW all-in-one diesel air heater takes #9 in this guide. It is sold as a single casing rather than a kit to assemble, and the listing bundles an LCD screen, a remote control, an air filter, air and exhaust pipework, a silencer and a mounting kit. Price is £63.99 and the rating is 4.7 out of 5 from 16 ratings. The advertised output is 8KW at a rated voltage of 12V, with an item size of about 15.3 x 5.7 x 5.7 inches.

That item size is the finding worth stopping on. It is the same figure the 5KW PRIJESSE unit carries in this guide: identical external dimensions, 3KW apart on the badge. The EVGTTI listing gives no second output figure that would settle which number is the real one. The rating breakdown is also awkward arithmetic — 83% five-star, 9% four-star and 8% three-star, set against 16 ratings in total, and 83% of 16 is not a whole number of buyers.
