What is a Hot Water Cylinder?

Your boiler is central to your home’s water system. But it also tends to rely on something else – the hot water cylinder. Such cylinders store the water, so they are clearly an important part of the whole network. There are two main types of hot water cylinder – vented and unvented.

Both have their benefits and drawbacks, but many find that an unvented water cylinder is a good choice when opting for a new boiler installation for their home or workplace.

Why might you need a Water Cylinder Service in Essex?

Vented Hot Water Cylinders Essex

  • Maintenance & Installation is typically cheaper and more simple
  • Reserves of water are stored in the tank should mains supply be cut off
  • Water pressure dictated by the height of the tank due to the gravity fed nature of the system
  • In relation to the above, you may find that upstairs taps are less powerful than those downstairs

Unvented Hot Water Cylinders

  • No water tank means that it can be installed in a variety of different places in the home
  • Stronger water pressure based on pressure from mains source
  • Takes up less space and is more future proof/up to date techonology
  • Installation & maintanence tends to be more expensive

Unvented Water Cylinders Essex

What is an Unvented Water Cylinder and how does it work?

An unvented hot water cylinder takes its water supply from the mains directly, rather than storing it anywhere nearby. It is connected directly to the main, so you will probably find that the pressure of your water is stronger than it would be with a vented hot water cylinder.


This type of water cylinder also has in-built safety features, something which absolutely appeals to many people who are rightly worried about being safe in their own home, or place of work

There are other benefits to an unvented hot water cylinder too. Because they don’t require any kind of a tank, they usually take up less space in your home. This is clearly hugely important for many people, and it is a massive perk of this type of water cylinder. They also tend to be more robust, and last longer than vented hot water cylinders.
