Modern heat storage in horticulture

Key aspects to consider in the design and maintenance of an efficient modern heat storage system. We consider insulation, storage and heating temperatures, the two types of stores, overall efficiency of design and how to size a heat storage system.

The fundamentals of heat storage in horticulture have not changed much since its introduction. However, modern systems are now seen more as a resource than just another functional part of a heating system. Even the language we use to refer to them reflects this. They were once referred to as ‘heat dump tanks’, whereas now they are ‘heat or thermal storage tanks’.

Finer points of the application of storage have been improved (for example, the control flow and temperature) and a wider range of heating sources has made heat storage more important in maintaining efficient operation of the whole heating system.

Growers who are thinking about, or who already have, heat storage should be aware of the characteristics and benefits, which are set out here, and be sure to specify a design which gives the lowest system running costs and highest overall benefit.
