Review: impressive water heater - great bit of kit and excellent value. Heats up a full tank very quickly and will keep the water hot for a couple of days if you then turn the while thing off. seems to be very efficient. haven't tested the wi-fi yet but even without it its a good water heater.
Review: Hot hot water - Replaced old green immersion tank work Evo 80 WiFi. Please note that I live in an electric only 4 bed house. The installer found the system easy to install and did not run into any difficulties. I have gone from a gravity fed system to a closed vented system. The hot water pressure is great. The system is quiet and one cannot hear anything. From a cold tank, first fill, and then turning it on one could feel the warmth in the water within 15 minutes. I have not ran out of hot water even after a shower and the water is Hot. On the app it is always showing as being around 50-51c, with the lowest at 45. I am running it on Eco mode. There is a template on where to drill the holes etc on the packaging box. With the App, it did not work straight away, but when I tried after a day, it registered and worked smoothly. The App itself way to use and gives all relevant information. The build quality of the unit looks and feels sturdy and of high quality. For the price, I cannot fault it and would highly recommend it

## Questions & Answers

**Q: Can this unit be mounted horizontally?**
A: 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.

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

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

**Q: can you use this product if wi-fi is not always availible?**
A: Dear Customer, 

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

Thanks.
Regards.
