Vesilämpövarasto

Vesilämpövarasto refers to a water-based thermal energy storage system. These systems are designed to store thermal energy, often in the form of heated water, for later use. The primary purpose is to balance the supply and demand of heat, particularly in conjunction with renewable energy sources like solar thermal collectors or heat pumps. By storing excess heat generated during periods of high availability, it can be deployed when demand exceeds immediate production.

The construction of a vesilämpövarasto typically involves a large insulated tank or reservoir filled with water. The size of the storage can vary significantly depending on the application, ranging from residential systems to large industrial or district heating networks. During charging, heat is transferred into the water, raising its temperature. This heat can then be extracted for space heating or hot water supply.

The efficiency of a vesilämpövarasto is influenced by factors such as insulation quality, the temperature difference between the stored water and the surroundings, and the control strategy for charging and discharging. These systems are a key component in improving the performance and economic viability of renewable heating solutions, contributing to reduced reliance on fossil fuels and enhanced energy system flexibility.
