Electric storage or instantaneous water heater
There are 2 large families of electric water heaters. You can therefore choose either the storage water heater or the instantaneous model. The storage water heater Also known as "cumulus", this type of electric water heater has a tank to keep the water hot. Its size will mainly depend on your hot water needs. The operation of this electric water heater is relatively simple. Cold water is introduced through the lower zone of the appliance, where it will then be heated, thanks to an electrical resistance. Depending on the model chosen, the heating system can be of the "soapstone" type, in other words the resistance is protected by a metal pipe, or of the "thermoplastic" type. In the second case, the resistance is directly immersed in water. Once the water is heated, it builds up at the top of the water heater, until you use it. The storage water heater will save you money if you have a discounted electric subscription during off-peak hours. The instant electric water heater This type of water heater has no tank. It is therefore less bulky than the storage water heater. It is advisable to establish it near the place where you will use the hot water, that is to say near the shower head, under the sink, under the sink ... The instantaneous water heater takes care of lukewarm water on demand, using an electric resistance. As soon as the tap closes, the appliance goes to rest.
