Choosing and Maintaining Hot Water Cylinders
Hot water cylinders are present in many UK households for daily hot water usage. There are two types usually: Direct and indirect.
Direct hot water cylinder
A direct hot water cylinder usually comprises a simple design. It is made up of a tank that is heated with an immersion heater. The water is then directly heated by the heater inside the tank. These are best for small households and with low demand for water. These are much less expensive than indirect cylinders making them perfect for those on a budget.
Indirect hot water cylinder
When compared to the others, an indirect hot water cylinder is much more complex. They have a heating coil that winds its way through the water reservoir. The coil is connected to a boiler. The water is therefore heated before it enters the cylinder. The cylinder acts as a storage reservoir for hot water. Therefore, there is now a reservoir of hot water to be used at the family's convenience. These types are also more efficient, making them ideal for larger households.
Factors to consider
When making a choice to buy hot water cylinders, one important factor to consider is the size of the cylinder, as this will dictate the amount of hot water the heater can hold. Large households obviously require a higher-capacity cylinder, with ten litres being the average amount of hot water consumed during a shower. The heating capacity and the element to be used is also important factor that can be decided by looking at power consumption, water type etc.
Cylinder construction
The construction of the cylinder can be done using many materials. Some of the commonly used ones are copper, stainless steel, ceramic and plastic. There are also various materials that can be used to construct hot water cylinders, including copper, stainless steel, and plastic. Copper is the most common, given its thermal conductivity and its temperature-resistant capabilities. Stainless steel is a good option because it is resistant to corrosion and rust. The newer versions that come also come with plastic cylinders, which are much more lightweight and save on installation costs. They, on the other hand, are not as durable as copper and steel.
It is very important to maintain these hot water cylinders so that they continue to function properly and efficiently. The cylinders need to be serviced and cleaned at the specified times, which is not that often, as modern cylinders are very damage-proof. Checking on the insulation periodically also helps prevent heat loss and saves on energy bills.
In conclusion, hot water cylinders are an important component of many UK households, supplying hot water for daily use. Direct and indirect hot water cylinders are the two main types available, with each offering different benefits and suited to different households. When choosing a cylinder, it's important to consider the size and type, as well as the materials used in its construction. Regular maintenance and insulation can prolong the lifespan of the cylinder and ensure it continues to function efficiently.
