The different types of water heaters
The presence of the water heater is essential in any habitat, which is why it is advisable to act at the first signs of weakness. This way you will avoid breakdowns and problems and you will have time to properly prepare your device replacement.
There are several types of water heaters:
tankless water heater
This model heats the water instantly, that is to say that it produces hot water as soon as you draw it from the tap for your shower or your dishes, for example. This device remains rare, because it is not very economical and it does not allow hot water to be produced during off-peak hours in particular.
Water heater with tank
This model produces hot water like the previous one, but it has a tank. It is therefore possible for you to program the heating periods during off-peak hours or to put it into forced operation in the event of an urgent one-off need. More economical, this system is the most widespread.
The cumulus
The cumulus, or hot water tank, accumulates hot water in a specific water tank. This device makes it possible to produce, accumulate and store a certain quantity of water in order to heat it.
On the market, there are four main types of water heater operation: solar, thermodynamic, gas and electric.
The electric water heater
The electric water heater is the most common. A distinction is made between the instantaneous model, which meets low hot water needs, because it heats on demand, without hot water storage, and the storage model which, on the contrary, stores water to supply the needs of ‘a family.
The water is heated by means of an electrical resistance. Its capacity is between 50 and 400 liters on average. Its installation is simple and it can operate during off-peak hours to achieve greater savings. On the other hand, it consumes a lot of energy.
Its pluses: Easy to install; multiple abilities; operates during off-peak hours; no maintenance.
Its minuses: Consumes a lot of energy.
The gas water heater
The gas water heater is primarily intended for small hot water needs, such as a sink. It is installed near a draw-off point.
The water is heated by a gas burner. Its maximum capacity is around 50 litres. Its use is less expensive than electricity, but its installation is more complex and requires specific connections. Moreover, unlike the electric, it must be serviced every year.
Its pluses: Cheaper to use than electricity.
Its minuses: Only suitable for a small draw; a mandatory annual interview; town gas connection required.
The thermodynamic water heater
This device recovers the heat present in the ambient air of the room in which it is installed. He uses it to heat the water it contains. To work, this device still needs an electrical backup. It is regularly installed in new constructions, because it uses renewable energy and it meets the criteria of RT 2012. However, its installation must comply with specific rules and may prove to be restrictive.
This system is equipped with a small heat pump which draws the necessary calories from the room. Its capacity ranges from 150 to 270 litres.
Its pluses: Very economical; compatible with RT 2012; eligible for financial aid; no specific maintenance.
Its minuses: installation constraints.
The solar water heater
This model remains the most economical, since it uses the energy of the sun to operate. It needs solar panels, to be placed on your roof or in your garden. These will capture the heat from the sun’s rays to return it to the balloon. Despite its advantages, this system is not widely used and is above all suitable for sunny regions, especially the south of France. Its capacity varies from 200 to 400 liters.
Its pluses: Uses free and renewable energy; compatible with RT 2012; eligible for financial aid.
Its minuses: Only suitable for sunny areas; very expensive to buy.
