lämminvesivarasto

A lämminvesivarasto, often translated as a hot water storage tank or indirectly as a domestic hot water (DHW) tank, is a component of a domestic hot water system. Its primary function is to store heated water for later use. This stored hot water is then available for various household needs such as showering, washing dishes, and laundry.

The lämminvesivarasto typically consists of an insulated tank that holds water. This water is heated by an external source, which can include a boiler, an electric heating element, a heat pump, or solar thermal collectors. The insulation of the tank is crucial for minimizing heat loss and maintaining the water at the desired temperature, thereby reducing the energy required to reheat it.

Different types of lämminvesivarasto exist, varying in size, material, and heating method. Some are direct heating, where the heating element is immersed in the water, while others are indirect, utilizing a heat exchanger coil within the tank. The size of the tank is usually determined by the hot water demand of the household. Proper sizing ensures that there is sufficient hot water available during peak usage times. Maintenance often involves periodic draining and flushing to remove sediment and prevent corrosion, ensuring the longevity and efficiency of the system.
