The supply of hot water in your home is incomplete without the installation of a hot water cylinder. But before you purchase and install one, you must do a little research and learn all things essential about it.
Why? Well, since an incompatible hot water cylinder installation can cause a great inconvenience for hot water supply in your home. Also, with frequent maintenance and high energy consumption, you’ll be spending more.
For your help to choose the right hot water cylinder, we have listed a few important things that you must learn about it. Follow the guide below and choose the best hot water cylinder for your home.
Hot Water Cylinder – How does it work?
The primary purpose of a hot water cylinder is to store hot water and to use it for gravity-based and mains pressure heating systems. There are two types of hot water cylinder available in the market. They are direct hot water cylinders or indirect hot water cylinders.
For a direct hot water cylinder, immersion heaters within the cylinder are used. In some, you may find more than one immersion heaters for enhanced performance. Whereas, for indirect hot water cylinders, it depends on other appliances, for instance, a boiler for generating hot water.
Although, in some indirect hot water cylinders you may as well find immersion heaters for extra heat generation.

What is a Vented Cylinder?
A vented cylinder is one which uses a gravity-based system instead of water pressure. Here the cylinder uses the cold water tank to draw water from it and then uses a heating source to heat up that water.
The water can either be heated directly using the immersion heater or indirectly using the central boiler system. For vented cylinders, a cold water tank is mandatory to release the air from the system and for also using it for water storage which later on will be used for heating.
This procedure omits the requirement for expansion vessels for dealing with trapped air in the system. The overall build of vented cylinders are simple; however, they can be slightly challenging for low water pressure.
What is an Unvented Cylinder?
An unvented cylinder is fed with water directly from the cold water pressure, sending in hot water to different water supplies at mains pressure. This offers improved water outlet performance.
The water present within the system is heated either with a central heating system or a solar-based technology. A cold water tank isn’t necessary for unvented cylinders. However, you would require a long list of safety mechanisms since it is a pressurised water system.
Most contemporary models of unvented cylinders are made of stainless steel that are better capable of withstanding high temperature and extreme pressure.
So, the next time you are in need of purchasing a hot water cylinder, make sure to go through this guide for best buy. After all, you would want to install the best water cylinder offering overall great efficiency.
