Finding an unvented cylinder service can be difficult when you need a reliable and efficient system. If you are in the market for an unvented cylinder, read on to find out what you should be looking out for and why we believed the Joule Unvented Cylinder could be the perfect product for you!

Vented Vs. Unvented Cylinders

If you are looking at hot water storage and supply options, then you will find there are many to choose from. Having narrowed your possibilities to a cylinder, you may be wondering what the difference is between a vented cylinder and an unvented cylinder, and whether the difference really matters to you.

The vented cylinder is a more traditional type of model. This requires you to have a water tank which would ideally be located in the attic, or somewhere high up. This is because gravity is used in this type of system to distribute the hot water throughout the home. This system requires an immersion heater or external source such as a central heating boiler to heat up the water.

The unvented cylinder utilises a pressurised system that can provide mains pressure hot water directly from the cold-water mains, instead of a cold-water tank. The cold water is pulled from the main water supply and heated either via electricity or gas, depending on the type of system.

What To Consider When Choosing An Unvented Cylinder

An unvented cylinder is the preferred option for many people because it requires less space to install, there is no need for a water tank, and because the water is coming directly from the main water supply. It is generally found that the water flow rates are better.

However, even if you have decided an unvented cylinder service is right for your home, there are a couple of considerations you must not forget about.

Cost will be a major consideration, because the price of an unvented cylinder is more than the traditional vented system. Not only that, but the unvented cylinder will require an annual unvented cylinder service, which means the maintenance costs of this type of system could be higher. However, it should also be noted that the running costs of an unvented cylinder are lower, and the system is more energy efficient.
