HEATING AND CLIMATISATION:
- Water heaters 
The boiler is a household or industrial equipment used to heat water by means of an energy source, which can be electricity, gas, fuel, a heat pump, or solar energy, which is increasingly used.
There are two main types of water heaters:
- Those who have a large reserve of hot water, they are also called hot water tank. In the case of electric water heaters, it has the advantage of warm water at night when electricity is cheaper. Also central heating boilers can heat domestic water.
- Those that heat water only upon request, at the time of withdrawal (tankless water heater).
