lämminvesivaraajasta
Lämminvesivaraaja, often referred to as a water heater, is a device used to heat and store water for domestic use. It typically consists of a tank where water is heated to a set temperature and stored until needed. The heating element can be electric, gas-fired, or powered by a central heating system. When a hot water tap is opened, the stored hot water is drawn from the tank, and cold water flows in to replenish it, initiating the heating process for the incoming cold water.
