Are you planning to purchase a hot water cylinder for your house? Before you do so, you should understand how a cylinder works, the different types of cylinders, their features, and the advantages that you can expect. Ensure you install a hot water cylinder that satisfies your requirements. Hot water cylinders are well-insulated tanks that are essentially found in domestic and commercial buildings to store and provide hot water for bathrooms, kitchens etc., when needed.

There are four types of hot water tanks: direct, indirect, vented, and unvented. 

Comparison between a direct and indirect hot water cylinder?

In a direct hot water cylinder, the water that is stored is heated straightforwardly through an immersion heater in the cylinder. This type is more expensive as it requires two immersion heaters, one for peak electricity and one for off-peak electricity. In comparison, an indirect hot water cylinder uses an external source such as an oil or gas boiler or thermal solar.

How to Determine the best Hot Water Cylinder for your house?

Hot water cylinder technology is constantly evolving, and there are many products available in the market nowadays. It is your responsibility to stay updated and select the right one that will suit your requirements. Choosing the right cylinder will save you from unnecessary future expenses and repairs. Here are a few points you should consider before you buy a hot water cylinder, whether it is an indirect or direct hot water cylinder for your home.

Cylinder Size and Size of Your Household

Hot water cylinders come in a range of sizes; it is up to you to choose the right size based on the number of family members in your house. If you get a cylinder that is too small, there are high chances of you running out of hot water. And, if you have a cylinder that is too big, it will only result in a waste of energy and high costs due to the storage of large amounts of water. A wide cylinder will technically have less heat loss due to its better SAP value and ERP rating and is hence preferred over a narrow cylinder.

Effective Heating and Use of Advanced Technology

Choose a hot water cylinder that is efficient in operation and design and takes less heating and cooling time. It is best to invest in a cylinder company that stays updated with the recent cylinder technology.

Neat Look and Space Efficient

You got to make sure that the cylinder is of a shape and size that will suit your space. Ideally, a hot water cylinder that is space efficient must have its heating coils connections, such as pipes and cables, well concealed for a neat look.

Energy Efficiency and Quality

The cylinder must be made of an optimal combination of quality materials for efficient operation, minimum expenses and a maximum lifetime. Whether a direct or indirect hot water cylinder, it should have less heat loss, maximum durability, and less energy consumption.
