Direct Cylinder vs. Indirect Cylinder: Difference and Comparison
By Muazma Batool & Muneeza Rehman — Published on March 12, 2024
Direct cylinders heat water directly using an internal element, while indirect cylinders use an external heat source to warm water through a coil.
Difference Between Direct Cylinder and Indirect Cylinder
Direct cylinders contain an electric immersion heater inside the tank to directly heat the water. This direct method allows for quick heating but relies on electricity. Indirect cylinders, on the other hand, are heated by an external boiler or solar thermal system, where water circulates through an internal coil, transferring heat to the water in the tank.

Direct cylinders are independent and can operate without a central heating system, making them suitable for homes without gas supply, indirect cylinders integrate with the household heating system. This integration can be more energy-efficient, as it uses the boiler or renewable energy sources to heat water.

The installation of a direct cylinder is generally simpler and less costly, as it doesn't require connection to a boiler. Indirect cylinders, requiring a boiler or solar thermal system, involve a more complex installation process, potentially increasing initial costs.

Maintenance requirements differ: direct cylinders, having fewer components (no external heat source or internal coil), might incur lower maintenance costs. Indirect cylinders, relying on a boiler and additional pipework, may require more frequent maintenance checks and potential repairs.

Direct cylinders are often chosen for their simplicity and independence, ideal for properties without gas or those needing a standalone hot water solution. Indirect cylinders are preferred for their efficiency and ability to be integrated into a central heating system, offering a holistic approach to home heating and hot water.
