Immersion heater: if there is no gas outlet and/or for second homes
If you cannot install gas in your home, or if it is a second home, we advise you to consider the option of the electric immersion heater.
It is very simple to operate: it accumulates a certain amount of water inside, heats it and keeps it at the temperature indicated.
The disadvantage is that when this volume is finished, there is no other option but to wait for it to fill up with water again and heat it to be able to use it. How much time are we talking about? It depends on the model and the quantity, but we’d say between one and three hours, more or less.
That’s why it’s crucial to determine how much water you’re going to need. Otherwise you’ll end up showering with cold water. Information for your calculations: each shower uses about 30 litres of water.
So if there are two people living in the apartment, you’ll need an immersion heater of at least 80 litres. With four inhabitants it will be better to opt for one of 100 litres and, if you are a large family, one of 250 litres.
Apart from its limited capacity, its greatest drawback is electricity consumption , which is more expensive than gas. The good thing is that you can solve this with the Endesa Tempo Happy Rate. You will have two hours of free electricity per day . So you can programme the heater for that interval.
Its greatest advantage is its versatility : fast, clean and cheap installation, it fits in any corner (both horizontally and vertically) and hardly needs any maintenance.
