Rated 5 out of 5 brilliant
the water heater is absolutely brilliant, easy to install, fits right under the kitchen unit with space around it to for electrician to wire it up, kicks out a lot of heat doesn't take ages to warm up, its really quite, easy to turn the heat down with the dial on the front of the heater. only fault I've come across is if you have really high pressure in your property or are you should definitely get a pressure reducing valve. over all a brilliant product will recommend to anyone who wants one

This should be pre-wired but was otherwise no problem to fit. It was a replacement for a 17 year old Dutch unit, so the ancillary equipment was already in place. The previous unit had worked without any problems or maintenance for 17 years before an electrical fault condemned it. Only when I received this (Italian) Ariston unit did I see in the (rather poor) instructions, that it had a sacrificial electrode requiring an annual inspection (involves removing the heater). Apparently, this is because the vitreous enamel tank lining may have tiny defects and the zinc electrode protects against this causing pin hole corrosion to the tank. The 3 year tank guarantee may be invalid if servicing of the electrode can not be proven.This type of appliance is very common in NL where there are at least 2 manufacturers who make them with copper tanks which are maintenance free. Screwfix should consider selling them instead of this inferior heater. The Dutch DIY company Hornbach, which is related to B&Q (like Screwfix a Kingfisher company) sell Inventum heaters with copper tanks for 179 Euro. I for one would have been happy to pay the little extra to get a superior maintenance free product. Finally, why don't Screwfix list reviews for all the Ariston water heaters they sell together. Apart from the size of the internal tank and heater rating, they are identical so comments for one model apply to all models.
In summary, it does what it says "on the label" but I downgrade it because of the choice of steel for the tank. This may affect long term reliability.

Rated 4 out of 5Â by xxxxxxxxxxxx Almost just a big kettle.
A very basic product with just as basic fitting instructions.
If this is a one off things you might like to buy at the same time are some ptf tape, a length of heat resistant cable, two flexible pipes with female connections at one end and appropriate connections for your installation at at the other. If your mains pressure exceeds 6 bar you will need to fit a pressure reduction valve. In areas of fluctuating high pressure it is best to fit one in any case.
The unit is quite compact, enclosed in a plastic insulation filled shell and feels sturdy enough, when working the external surface is mostly cool indicating a good level of insulation. There is a little heat, nothing to cause concern, in the area of the control panel where there is not as much insulation.
A bracket, without fixings, is provided for wall mounting or it can sit under a sink. A 6 bar pressure release valve is provided and you will need a T to include it if fitting new pipe work.
Once you work out how to get the cable in through the conduit at the bottom rear and connected up the terminals by removing the front panel installation is easy. I think they could have pre-fitted an appropriate cable. The instruction manual is almost generic and of minimal help in illustrating the unit or panel removal. It has a plumbing diagram showing the correct location of the pressure release valve and minimum pipe requirements to allow for water expansion.
It is a good enough unit but my feeling is that the manufacturer could have been a little more helpful in describing the unit in the installation instructions.
It is very similar to larger units of this type found in other parts of Europe at lower cost. Maybe in the inflated UK market it is good value.
