A good machine smokes first prize. The heating time is certainly a bit long, but it's not the most important. It offers a DBiT decent enough. Just a dtail, I'm not sr it has a rel DBiT of 70m3 per minute, because I possde another machine of the same type (fogstar Starway 700w) announcing the DBiT but is even more powerful. But hey, I have not measured it's just an impression.
Apart from a, it's a good deal trs.
