Which is the best unvented pressurised hot water cylinder

[turnitup59]

Hi,
I'm looking to put an unvented indirect hot water cylinder (approx 200litres) in the loft. My plumber recommended the Ariston Primo cylinder but I wanted to canvas other opinions.

Which are the" best buy" cylinders?

Many thanks

The Primo is consistently made in one of the most automated and modern plants of its type. It is a no frills design but we have never had a problem with one, apart from the feet breaking off and a clumsy thermostat design. The former has been improved.

You already have been recommended a budget unvented cylinder.

Thanks for the quick response.
It's not necessarily a budget cylinder that I'm looking for, more a reliable, long lasting one at a reasonable price.

Does the Ariston still fit the bill?

In my opinion, yes. You could also look at the Range/Copperform/Kingspan offering (they are all the same), these are also branded Worcester Bosch.

remember how heavy a 210litre cylinder is going to be, or you will have more to worry about than its wonky feet

I used to like the Santon which is an all stainless steel "second name" of Megaflo and a lot cheaper with the added advantage of having a seperate expansion vessel.

Most of these cylinders are much the same now,some earlier models had issues but they are all pretty much ironed out

The premium range would be the OSO and the Heatrae Sadia Megaflow,but not much in them

I use plumbcenter own brand, Range and kingspan as well as Santon for budget range of cylinders its all stainless steel with same long warranties which we will have to see if the manufacturers will honour

Some people now ask us to fit twin coil,which is not a bad idea because if you choose to have solar later then the rest of the heating system is all set up for it

OSO Super S every time for me, only theoretical downside is that they're single coil only, so you can't fit solar panels to them, but unless you're both feeling flush with cash and a bit of an eco-warrior, you won't want solar anyway so it's probably not an issue

OSO do have a twin coil solar cylinder.

Indeed they do, but it's not the Super S, it's also a bubble-top which I'm not a fan of (although admittedly they do now recommend it's fitted fully-flooded with a separate EV)

No one mentioned The Main (Baxi) range. Any particular reason. I am told that thet are made in same factory as Megaflo.

Vaillant Unistor are good too.

Viessmann Vitocell and the OSO get my vote.
