Pros
Cons
All parts are copper or brass It works very noisily, vibration is felt.. Replaced the air fan, noise and vibration decreased slightly just bought Italtherm CITY CLASS 25 F i recommend it don't buy |
Copper heat exchanger, brass hydraulic group, easy to maintain, all components are of high quality, European. Convenient settings, digital knobs, not mechanics as some reviews say. All intervals can be set in those menus, if it turns on often, depending on the volume and length of the coolant, you can set the heating operation delay as you like. Water heating is good, smooth, there are no temperature changes, enough for 2 points. A little noisy. With factory settings, the heating turns on (clocks) every minute. use Italtherm CITY CLASS 25 F few months |
You won’t sleep with him, or you’ll get used to such a stupid mode of operation Mechanical twisters Loud, minimum temperature lights up and turns off every 2 minutes use Italtherm CITY CLASS 25 F more than year |
