Seasonal thermal energy storage - Wikipedia

Heat storage is a condition of some wood boiler warranties and EPA approvals. Using a properly sized heat storage system with wood pellet and wood chip boilers can reduce on/off cycling by half or more. Reducing cycling dramatically decreases emissions and the need for boiler service, while improving heating response time. This means less ash creation and a higher degree of building occupant comfort. While not all boilers sold by Tarm Biomass require thermal storage…

Luisa F. Cabeza, Eduard Oró, in Renewable Heating and Cooling, 2016 7.2.3.1 Underground thermal energy storage. Underground thermal energy storage (UTES) with both boreholes (BTES) and aquifers (ATES) are the most developed storage concepts and are mostly used for seasonal storage. The description of the concepts can be found in Paksoy (2007) and Mehling and Cabeza (2008).

Wood Boiler - Heat Storage — Heating Help: The Wall

The storage medium in a TES can remain in a single phase (so that only sensible heat is stored) and/or undergo phase change (so that energy is stored as latent heat). Sensible TESs (e.g., liquid water systems) exhibit changes in temperature in the store as heat is added or removed.

THERMAL STORAGE

Optimized Combustion by allowing the boiler to run "wide open". The heat storage acts as a buffer between the boiler output and the house's heat demand. Heat is supplied by the boiler when there is a demand by the house. When demand falls then heat is diverted to the storage tank. When wood has burned out, heat is supplied from the storage.
