There are many things it is almost impossible to live without, things in which we use every day without even realizing. One of these things is warm liquid. It can be easy to take it for granted, but we would quickly notice if we were without it for even just one day. Many of us fail to think about the devices that make it possible for us to have such simple access to warm liquid. Whether you realize it or not, every household has some form of hot water cylinder that enables us to turn on a tap and receive instant warm liquid.

Keep reading to find out some interesting facts about hot water cylinders given by The Cylinder Guy:


Fact 1: In our society, it is incredibly easy to take hot water cylinders for granted. However, it is important to remember that it wasn’t always this simple to have access to warm liquid. The reality is, systems to warm liquid never used to exist. So where did the first heating system originate?

Interestingly, the first system to provide warm liquid was created by a man in England in 1868. The system he devised worked by flowing cold liquid through pipes that were exposed to a burner of scorching gas. As the liquid flowed through the pipes it was heated and dispensed into a sink or tub where it could be collected.


Fact 2: There are several different types of hot water cylinder, but they can be divided into two main sub categories: tank systems and tankless systems. There are benefits to both types and the system you opt for will depend on a variety of different factors including your preference and what will work best in your home.

It is important to understand that these systems do differ in many ways, though. For example, tankless systems will often last somewhere between 18-20 years, whilst their tank based counterparts are more likely to last between 10-12 years.

These systems also differ in price, with tankless devices sometimes costing almost double the amount that tank based devices cost.


Fact 3: There are some things that are unavoidable in life; one of these things is utility bills. As frustrating as it is, you have to pay your bills or you will be disconnected from vital services. But have you ever wondered how much energy it takes to power your hot water cylinder? For a normal household, about 25% of the energy used in the home goes towards heating liquid. When this is converted into monetary value, it is quite shocking how much is spent on just warming up liquid. However, there are ways in which you can reduce your energy bills. If you opt to invest in a high efficiency hot water cylinder, rather than a standard one, you can actually cut your energy use by anywhere between 10%-50%. Essentially, if you invest in a good quality, efficient device, you will save money in the long run.


Fact 4: There are so many different types of hot water cylinder, from gas to electric to solar powered. Your home, and your geographical location will have an impact on which system is most appropriate for you. Whilst we now have options, this was not always the case.

Before the invention of modern devices, there were very few alternatives. The most common way of heating liquid involved the use of a pipe known as a water-back. This pipe was connected to the stove which provided the heat to warm the liquid, as the liquid was heated, it would move through the pipe to a storage tank where it would be collected.
