Why Choose Watertite for Vented & Unvented Hot Water Cylinder Installation & Repair?
Whether you’ve got a vented or an unvented hot water cylinder, they’re essential to the performance of your boiler. In fact, without vented or unvented hot water cylinders, there’d be no hot water in your home at all.
Which is why if you’re only receiving an intermittent or no supply of hot water, the problem probably lies with your water cylinder.
But it’s important to know about the two different types of water cylinders – even if they’re not causing you any trouble.
Buying the right boiler for your home, and getting the best performance, is dependent on buying one with a cylinder that fits the needs of your household.
Choosing the right cylinder should be based on a few factors, such as the number of people in your household, how often and how long you use hot water, when you use it, and the overall cost needed.
But before we get to that, let’s answer a few burning questions first.
What’s the Difference Between Vented and Unvented Hot Water Cylinders?
Every type of boiler relies on cylinders to store hot water. The main difference is how these cylinders get their supply of water.
In a nutshell, vented cylinders require a cold water storage tank (often installed in a loft), while unvented cylinders get their supply directly from the cold mains water feed.
Vented cylinders need a pipe and a tank. These components work two ways: 1) water is heated within the tank so you can use it for your taps and showers; and 2) the vent pipe and tank can house expanding water when it is heated.
Unvented cylinders remove the middleman, so to speak, by connecting directly to the mains. It has built-in features that can accommodate excess water as it heats and expands.
Each cylinder comes with their own pros and cons:
|Vented Water Cylinders|
|Simple and cheap.||Water pressure can be lower, as this type of cylinder relies on gravity. The more height there is between tank and shower means the pressure will be stronger.|
|You have a backup water supply in case your main supply is turned of||Given that it relies on gravity, expect your shower and taps upstairs to have weaker pressure than that downstairs. Some households require an additional pump for better water pressure.|
|Requires almost no maintenance.||Takes up more space, since you also need to install a cold water tank.|
|Unvented Water Cylinders|
|Needs less space, giving you flexibility where you want it installed.||Involves a more advanced technology, which means it would cost more for installation and maintenance.|
|Stronger water pressure.||If your main supply is turned off, you won’t have a backup water supply.|
|Its sealed system removes the risk of contaminated water within the tank or frozen water during winter.||Incompatibility with modern power showers and mixers.|
