There are both gas and electric models and they have a low cost and are suitable for large families. They use natural gas, propane, fuel oil, electricity,

or wood to heat water and store it in a tank. Disadvantage: once the water stored in the tank runs out, you must wait for the water heater to heat up more water again.

 

2. The tankless water heater. It can be gas and electric, and it produces hot water when needed but in limited quantities. Disadvantage: It is generally more expensive, and its water flow rate may be less than usual. when several taps are opened together (e.g. bathroom tap, shower, kitchen tap).

 

3. The hybrid water heater features a heat pump that uses heat from the outside air to heat water and then stores it in a tank. Disadvantage: water heating is tied to external factors that could decrease hot water production.

You can choose between a water heater equipped with circulation pumps and controls and a passive type that doesn’t use pumps or controls. Disadvantage: this type of water heater is closely related to external factors that could decrease hot water production.
