Can this unit be mounted horizontally?

I’m not 100% sure but have see images of this mounted both vertically and horizontally, the mounting brackets on the back would allow for this. The Ariston Facebook page also has a video of it mounted both ways but would be worth messaging them directly to get a proper answer.

My flat has a 2 bars pressure, will that be enough if I replace my unvented inderect cylinder with the Velis?

Good Morning, Thank you for your question. A cold water supply pressure between 1 and 3.5 bar is required (if the mains pressure is above 3.5 bar a pressure reducing valve must be installed). Regards.

Can 45l tank provide enough hot water for one bath. I live alone and have a separate electric shower.

A standard bath is about 180ltr so maybe not really enough, if you set it to max temperature and mixed cold to increase the volume you may possibly push it to 63ltrs but this would be pretty shallow for bathing.

can you use this product if wi-fi is not always availible?

Dear Customer, It can be used with or without Wi-Fi, the Wi-Fi is just an option. Thanks. Regards.
