Everything You Need To Know About Hot Water Cylinders

We often forget how lucky we are to have easy access to warm liquid. In our society, it is as simple as turning on a tap, but we often don’t think about the appliances that make this happen. However, as soon as our devices stop working, it becomes a main priority to fix or replace it. It may come as a surprise to you, but there are so many options in regards to hot water cylinders, and the type you purchase will depend on where you live and your household. Unless you know a lot about how these systems work, it can be challenging to know which will be the best match for you. In order to help you understand the different options, The Cylinder Guy has given some tips you need to know about hot water cylinders.


What are the different types of hot water cylinders?

There are, in fact, several different types of system that you can choose from when it comes to replacing your hot water cylinder. As with anything, each system has its own positive attributes as well as its drawbacks.

One of the most popular options at the moment are known as electric systems; these work through heating the liquid with an element in the bottom of the unit. After the liquid has warmed up it is stored in a tank where it is ready to be used throughout the day. Many people opt for electric systems because they are the most affordable to buy, but it is important to understand that they are one of the most expensive systems to run.

In countries that have exposure to lots of sunlight, such as Australia, solar powered devices are also an alternative. Essentially, solar power is used to heat the liquid rather than making use of electricity. Although solar powered hot water cylinders are expensive to install, they are environmentally friendly and incredibly affordable to run.

Another popular option is a gas structure. Gas devices are arguably one of the most widely used within Australia simply because they are cost effective and highly efficient. The main benefit of these systems, though is that they provide instant warm liquid throughout the house. This takes away the annoyance of having to wait for the liquid to heat up when you turn on the tap.


Vented vs Unvented?

Many people fail to realize that hot water cylinders can be divided into two categories; vented or unvented. However, unless you’re an expert these terms probably don’t mean much to you. You may find yourself wondering what these terms actually mean and what the difference between the two is.

A vented structure is a more old fashioned approach and often works through a cold liquid storage tank. This tank is generally stored in the loft or the attic. Essentially, the tank will supply the cold liquid to the warm liquid chamber, through the use of gravity. At this stage an immersion heater or a boiler will warm the cold liquid before it is allowed into the warm liquid chamber. Vented systems are relatively simple and are quite an affordable option. However, these systems take up a lot of space and often provide a low pressure of liquid when it comes out of appliances.

Unvented systems are completely different and don’t require a cold storage tank. Interestingly, they work through a pressurized system which is supplied directly from the mains water. It is possible to use either central heating or an immersion heater for unvented systems.
