Like the sound of an unvented cylinder, but aren’t sure which one to pick?
There are so many great benefits of fitting a system boiler with an unvented cylinder, such as fantastic water pressure, greater energy efficiency, and all the heating and hot water your large property will ever need.
If like many of my customers, you’re attracted by many of the benefits above, then an unvented cylinder is probably the best solution for you, although it can be a pricey investment.
Below, I’m going to give you a run-down of three of the best unvented cylinders on the market, to help make your choice a little easier.
Superwarm’s Top Unvented Cylinder Picks
Before I get started, it’s important to note that apart from the price, there’s not really any major drawbacks to any of these options – an unvented cylinder is essentially a big insulated steel tank that does what it says on the tin. There’s not really many components that can possibly go wrong, so it really just falls down to brand and how much you are prepared to spend.
Most popular unvented cylinder brand: Megaflo
Megaflo is probably the biggest household name when it comes to unvented cylinders. The website states that these particular cylinders are constructed from duplex stainless steel, and because of this they offer a “superior resistance to corrosion”.
Every unit goes through a very thorough testing process in the factory, where the pressure is increased to 15 bars – five times the usual operating pressure for these cylinders.
Price: £1100 (Supplied and fitted)
Best new player to the market: Worcester Bosch
You should know by now how I feel about Worcester Bosch; it is a premium brand company offering premium brand products, with superior, no-quibble guarantees and dedicated engineers. However, Worcester Bosch ‘Greenstore’ cylinders are a tad on the pricey side, so I’d only recommend opting for one of these at the moment if your boiler and controls are also from the Worcester Bosch brand. Which means Worcester give a great brand package guarantee.If not, I’d save your money and go for one of the better value cylinders.
Price: £1400 (Supplied and fitted)
Longest unvented cylinder guarantee: Santon
The main reason Santon is on this list is because of the extra-long 30-year guarantee – compared to the 25-year-guarantee you’ll get with the others. There are two unvented cylinders in the range: the PremierPlus and the PremierPlus SystemFit. Because they are manufactured to very stringent standards, these units are also resistant to corrosion and have a long life expectancy – something that Santon has backed up with its particularly good guarantee.
Price: £1100 (Supplied and fitted)
Best overall value unvented cylinder: GledHill
My top pick for the best overall value unvented cylinder is without a doubt, Gledhill. They’re manufactured in The UK which is a huge plus as I can always get hold of them when needed, and they also have a great guarantee.
Their range of unvented cylinders are all manufactured using only the highest grade of stainless steel, making for strong and durable containers you can rely on.
Price: £1040 (Supplied and fitted)
There are so many reasons to choose an unvented cylinder for your large property, such as the fantastic water pressure, greater energy efficiency, and all the heating and hot water you’ll ever need. And the good thing about unvented cylinders is that not much can go wrong with them – it all comes down to which brand you prefer and the price you’re willing to pay.
Choose from popular brands such as Megaflo, premium brands like Worcester Bosch, or great value brands like Gledhill. You could even get a 30-year-guarantee if you decide to opt for Santon.
