Is an Unvented Cylinder Better Than a Vented Cylinder?

The ability to heat and store water in our homes reduces wasted time and effort and adds a lot of convenience to our lives. However, there are several options available to you in terms of how you achieve that. For UK residents, the primary choice is between vented and unvented cylinders.

Once, unvented cylinders were the only option, but today more and more people are choosing to go the unvented route. Are unvented cylinders actually better? Yes, they are, but you’ll need to know a little more to understand why that’s the case.

Why Unvented Cylinders Are Better Choices

For most UK residents, unvented boilers are the better choice. Why is that? There are several reasons.

  • Good Pressure – An unvented cylinder ensures good water pressure at all of your taps, including upstairs taps.
  • Good Flow – Using an unvented cylinder helps provide good flow of hot water from all your taps.
  • No Cold-Water Tank – With an unvented water cylinder, there is no need for a cold-water tank located in the attic. This is good news for homes without much in the way of upstairs space.
  • No Mains Pressure – If your home has low pressure from the mains, then an unvented cylinder can increase your hot water pressure (but only for the hot water).

As you can see, there are many advantages to installing an unvented cylinder. However, there are some drawbacks that should be considered, as well. For instance, unvented cylinders are usually more expensive than vented cylinders. For most residents, better access to hot water and improved water pressure are enough incentives to offset that additional cost. Unvented cylinders also require a specialist touch. Only plumbers certified to work on unvented systems can handle installation, maintenance, and repairs.

You will also need to make an informed choice about your water cylinder. There are many different manufacturers, and each has their own set-up in terms of heating elements and even heating type (direct vs. indirect, gas vs. electric, etc.). Working with the right heating engineer can help ensure you make an informed decision.
