Rated 5 out of 5 by from Good heaters,need maintenance I have replaced older heaters with these due to the cost of replacement unvented taps. I have had some on site for 6 years now. There are 12 on site all with no problems. You need to check the anode each year and clear out the tank of hardness deposits(anodes last 2 years on mine). It helps if you install these so they can be easily maintained. If you do not do the maintenance any hardness will reduce the effective storage volume, possibly over heat the element and allow corrosion. You can just replace it every few years instead of maintenance, a nice little earner for dodgy plumbers.

Rated 3 out of 5 by from grit in water Easy installation and rapid heating however must be used without a tap aerator / filter due to a fine gritty silt from the heater blocking the filter.

Rated 5 out of 5 by from Nice piece of kit I bought this for a replacement for an older unit that picked up and it was very easy to install although it doesn’t come with a power flex so it’s advisable that you keep the previous cord, all in all tho it’s a much nicer looking unit and much faster.

does this water heater come with an electric power cable coming out the back of it

Asked by: maxyboy11
No. You have to buy heat resistant 1.5mm 3 core cable.

Expansion vessel

I'm replacing two old 15 litre 2kw ariston water heaters with the newer model. Can I use the old expansion vessels or do I need new ones?
Asked by: Jimmy750
You can use your old ones if they are ok , re-pressurise them to 3bar when disconnected from pipework .

My water pressure has been measured at a minimum of 0.8bar. Will this be an issue with this water heater? thanks

Asked by: dmat
Hi, It won't present an issue, please keep in mind the outlet pressure will be the same as your mains pressure. Thanks Ariston UK

My cold water supply has a variable pressure - it comes from a natural spring, plus tees-off to other users. Will that be an issue with this water heater? thanks

Asked by: dmat
Your inlet pressure should be between 1 and 3.5 bar, any greater than this, you will need to install an inline pressure reducing valve. The unit has a magnesium anode that protect the unit, this has to be checked yearly and replaced if necessary. Depending on water types the anode could become inactive quicker, shortening the life of the heater. therefore more regular servicing may be necessary.

Is a expansion vessel required or just water in, out
Asked by: Fab2
Hello, Yes an expansion vessel would be required. The correct one for this unit would be Screwfix Product Code: 21261. Thanks
