Rated 5 out of 5 by from The best in my opinion The most Easy and powerful water heater I ever install.

Rated 2 out of 5 by from Heavy when full! This thing fell off the hooks it comes with and wiped out the fused spur it was powered from. It snapped the push fit hose and flooded the place!! As a water heater it's fine although the mounting is precarious at best!! I would recommend rethinking things and ensuring it is anchored properly to the wall before using.

Rated 5 out of 5 by from Hot water on tap Finally got my water heater installed by a G3 qualified plumber and so far we are very pleased. There was initial confusion as Screwfix did not supply the expansion tank, none return valve or pressure reducing valve. After speaking to Ariston they sent me the missing parts free of charge. We purchased the 30ltr model and these parts are required for installation. The Ariston website states that these parts are included and they should be supplied in a separate package.

Rated 5 out of 5 by from Water Heater Quite bulky so needs a bit of space. Does all I need for cleaning duties. Enough hot water to fill a large sink or 2 large buckets. Re-heats very quickly. Very good price compared to other outlets. I would recommend this unit. Very happy.

Does the 30ltrs come with additional parts?

On Ariston website the 30ltrs vessel comes supplied with the expansion vessel, Pressure Reducing Valve (PRV), tundish and check valve. Can you please confirm this unit comes with all of the above?
Asked by: Heretohelp
No. Must be installed with the Expansion Vessel (Code 21261), Discharge Tundish (Code 79926) and if mains pressure is over 3.5bar then the Pressure Reducing Valve (Code 44939) is also required.

Hot water supply for shower

Hi, Can I use this to provide the hot water supply to a mixer shower? Will the flow rate keep up or is it likely to give a 'dribble' for a shower? Can you recommend anything if this isn't suitable?
Asked by: Bitkrusha
Hi, You can use the unit to supply a mixer shower. The flow rate will depend upon your water pressure, the unit has a maximum of 3.5 Bar. A 30L model will only give you a few minutes of hot water (at a typical shower flow rate 8-10lt/min) so please consider this before you purchase. Thanks Ariston

Can I use this to replace a hot water cylinder in an airing cupboard?

The customer has an electric shower, so this unit would only be supplying a kitchen sink and basin in bathroom. They want the 30 ltr model and I do have my unvented hot water qualifications
Asked by: Chris90
Hi Chris, Thanks for your question. Yes the 30 L is subject to G3 Regulations and you'll be able to install it no problem. As long as the capacity is sufficient for their needs then it'll be suitable (it sounds like it will be more than adequate to serve a kitchen sink and basin). Just be mindful of expansion requirements (install 2 litre vessel if necessary). Thanks Ariston

under sink placement

Hi there, I've just read whole g3 specs and I still don't understand why this product cannot be installed under sink. Could you please specify the reason as much as possible? Thanks
Asked by: themaintenanceguy
Hi, After checking with the technical team, it would seem that as long as the unit is installed and commissioned to G3 specifications it can indeed be installed "under sink". Thanks Ariston
