Indirect Cylinders

Indirect Cylinders

Indirect water cylinders, also known as thermal stores, are heated by an external heat source, such as a boiler or a heat pump, and they contain a coil that transfers the heat to the water inside the tank. Indirect models are more efficient than direct ones, and they can be powered by various heat sources, including renewable energy sources. They are suitable for most households and can provide hot water to multiple taps simultaneously

In an indirect tank, cold water from the main supply is circulated through a coil of piping in the tank. This coil is heated by the heating source, which warms the water in the tank. The hot water is then drawn off as needed for use in the building.

One of the benefits of these systems is that they are very efficient. Because the heat source is separate from the storage tank, the system can be designed to maximise the energy efficiency of both components. Additionally, they are generally very reliable and require little maintenance. Another advantage is that they can be easily integrated with other types of heating systems, such as solar water heating systems or heat pump systems. This makes them a flexible and versatile option for many types of buildings. The Gledhill Envirofoam Copper is an excellent illustration of this point.

Overall, they are a popular choice for hot water heating due to their efficiency, reliability, and versatility.
