What is an Unvented Cylinder

An unvented cylinder is a type of hot water storage system that does not rely on gravity to provide water pressure.

Instead, it uses a pump to deliver hot water to taps and showers throughout the home. Unvented cylinders are becoming increasingly popular as they offer a number of advantages over traditional gravity-fed systems.

One of the biggest advantages of unvented cylinders is that they provide a much higher flow rate of hot water.

This is because they are not limited by the height of the water tank. As a result, you can get a hot shower or fill a bath quickly and easily.

Unvented cylinders are also more energy-efficient than gravity-fed systems. This is because they do not lose heat as the water travels through the pipes. As a result, you can save money on your energy bills by using an unvented cylinder.

Finally, unvented cylinders are much easier to install than gravity-fed systems. This is because they do not require a high water tank to be installed in the loft. As a result, they can be installed in any room in the home.

If you are looking for a new hot water storage system, an unvented cylinder is a great option. They offer a number of advantages over traditional gravity-fed systems, including a higher flow rate, better energy efficiency, and easier installation.

Here are some of the benefits of using an unvented cylinder:

Increased flow rate: Unvented cylinders provide a much higher flow rate of hot water than traditional gravity-fed systems. This means that you can get a hot shower or fill a bath quickly and easily.
Improved energy efficiency: Unvented cylinders are more energy-efficient than traditional gravity-fed systems. This is because they do not lose heat as the water travels through the pipes. As a result, you can save money on your energy bills by using an unvented cylinder.
Easier installation: Unvented cylinders are much easier to install than traditional gravity-fed systems. This is because they do not require a high water tank to be installed in the loft. As a result, they can be installed in any room in the home.

If you are considering installing an unvented cylinder, it is important to consult with a qualified plumber or heating contractor. They can help you determine the best type of cylinder for your needs and install it properly.

Here are some of the factors to consider when choosing an unvented cylinder:

Size: The size of the cylinder will depend on the number of people in your household and the amount of hot water you use.
Type: There are two main types of unvented cylinders: direct and indirect. Direct cylinders are heated by an immersion heater, while indirect cylinders are heated by a boiler.
Features: Some unvented cylinders come with additional features, such as a thermostat or a timer.

The cost of an unvented cylinder will vary depending on the size, type, and features of the cylinder. However, they are generally more expensive than traditional gravity-fed systems. However, the benefits of using an unvented cylinder can make it a worthwhile investment.

Here are some of the safety features that are commonly found on unvented cylinders:

Pressure relief valve: This valve is designed to release excess pressure from the system if it gets too high. This helps to prevent the cylinder from bursting.
Temperature relief valve: This valve is designed to release hot water from the system if the temperature gets too high. This helps to prevent the water from boiling and causing scalding.
Expansion vessel: This vessel is designed to absorb excess water as the water in the cylinder expands when it is heated. This helps to prevent the pressure in the system from getting too high.
Thermostat: This thermostat is designed to turn off the heating element in the cylinder when the water reaches a certain temperature. This helps to prevent the water from boiling and causing scalding.

It is important to have these safety features checked and maintained on a regular basis by a qualified plumber or heating engineer. This will help to ensure that your unvented cylinder is safe to use.
