Then this article is of interest to you. Why? In <a href=\"https:\/\/www.paratureforma.com\/\" target=\"_blank\" rel=\"noopener\">ParaTuReforma<\/a> we want to <strong>analyze the energy efficiency of an electric water heater<\/strong> in order to allow you to find out if it is really the appliance you need. Do not miss it.    <\/p>\n\n<h2 class=\"wp-block-heading\">Electric water heaters<\/h2>\n\n<p>A <strong><a href=\"https:\/\/www.paratureforma.com\/termos-y-calentadores\" target=\"_blank\" rel=\"noopener\">electric boiler<\/a><\/strong> is a water tank with a certain capacity that contains a set of heating elements. These elements are in charge of raising the temperature of the water so that, later, it comes out through the faucets of the sink, the shower, the sink and the bidet according to the user&#8217;s demand. <\/p>\n\n<p>Undoubtedly, it is a device that offers many advantages, which is why it has become one of the preferred options for users. Let&#8217;s take a look at them: <\/p>\n\n<ul class=\"wp-block-list\">\n<li> <strong style=\"font-size: inherit;\">Immediacy<\/strong><span style=\"font-size: inherit;\">. Once the faucet is turned on, the water comes out hot almost instantaneously. <\/span> <\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Ease of installation<\/strong><span style=\"font-size: inherit;\">. Simply drill a series of holes in the wall using a drill, attach the hooks and hang it up. It is then connected to the water mains and a plug and is ready for use.  <\/span> <\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Sustainability<\/strong><span style=\"font-size: inherit;\">. This type of water heater does not use fossil fuels to heat water, such as butane gas or natural gas. This means that their level of pollutant gas emissions is practically zero.  <\/span> <\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Low maintenance<\/strong><span style=\"font-size: inherit;\">. Electric heaters only require annual replacement of the magnesium anode to reduce water hardness. The safety valve and the heating element must also be checked.  <\/span> <\/li>\n<\/ul>\n\n<p>To all this we must add that <strong>an electric boiler does not require a minimum flow of water<\/strong>. This makes them ideal for environments where the liquid reaches the house with very little pressure due to the lack of its own group. <\/p>\n\n\t\t<div class=\"ic_cta_wrapper\">\n\t\t\t<div class=\"ic_cta_banner\">\n\t\t    <a href=\"https:\/\/www.sharp-liskov.213-165-74-80.plesk.page\/piscina-de-obra-o-desmontable-3\/\" onclick=\"ic_cta_track_click_4865()\" class=\"ic-cta ic-cta-generic\" title=\"CTA 7 - Construcci\u00f3n piscinas\" 1>\n\t\t      <img decoding=\"async\" src=\"https:\/\/sharp-liskov.213-165-74-80.plesk.page\/wp-content\/uploads\/2023\/05\/CTA7-Post-ebook-ventajas-piscinas-obra-desmontables.png\" alt=\"CTA 7 - Construcci\u00f3n piscinas\" title=\"\">\n\t\t    <\/a>\n\t\t\t\t<script>\n\t\t\t\t\twindow.onload = function(e) {\n\t\t\t\t\t\tga('send', 'event', {\n\t\t\t\t\t\t\teventCategory: 'CTA 7 - Construcci\u00f3n piscinas',\n\t\t\t\t\t\t\teventAction: 'view',\n\t\t\t\t\t\t\teventLabel: 'https:\/\/sharp-liskov.213-165-74-80.plesk.page\/en\/wp-json\/wp\/v2\/posts\/19470',\n\t\t\t\t\t\t\tnonInteraction: true\n\t\t\t\t\t\t});\n\t\t\t\t\t}\n\n\t\t\t\t\tfunction ic_cta_track_click_4865() {\n\t\t\t\t\t\tga('send', 'event', {\n\t\t\t\t\t\t\teventCategory: 'CTA 7 - Construcci\u00f3n piscinas',\n\t\t\t\t\t\t\teventAction: 'click',\n\t\t\t\t\t\t\teventLabel: 'https:\/\/sharp-liskov.213-165-74-80.plesk.page\/en\/wp-json\/wp\/v2\/posts\/19470'\n\t\t\t\t\t\t});\n\t\t\t\t\t}\n\t\t\t\t<\/script>\n\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n  \n\n<h2 class=\"wp-block-heading\">Consumption<\/h2>\n\n<p><strong>The energy consumption of an electric boiler <\/strong>is very difficult to determine exactly. This is mainly due to the fact that many factors come into play. Most of them are related to the characteristics of the appliance itself, as you will see below:  <\/p>\n\n<ul class=\"wp-block-list\">\n<li> <strong style=\"font-size: inherit;\">Capacity<\/strong><span style=\"font-size: inherit;\">. Obviously, the larger the capacity of the water tank of the boiler, the more energy the heating elements require to reach the desired temperature. Currently, almost all models on the market range from 50 to 200 liters. The choice will depend on the number of people living at home.   <\/span> <\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Tank insulation<\/strong><span style=\"font-size: inherit;\">. Depending on the materials from which it is made, the heater will preserve the temperature of the water stored inside better or worse. <\/span> <\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Type of resistance<\/strong><span style=\"font-size: inherit;\">. There are two types. Armored electric heaters are in direct contact with water and therefore heat it faster. However, they are very sensitive to limescale and have a relatively short service life. On the other hand, sheathed ceramic electric heaters are less sensitive to this element, but require more effort to increase the temperature.    <\/span> <\/li>\n<\/ul>\n\n<p>Now,<strong> how do you calculate the energy consumption of an electric boiler? <\/strong>To do this, it is essential that you take a look at the technical data sheet of the device in search of two pieces of information: the power in kW (if it appears in watts, you only have to divide the figure by 1000) and the time in hours. Then multiply both figures and you will have the result in kWh. <\/p>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"545\" height=\"545\" src=\"https:\/\/www.sharp-liskov.213-165-74-80.plesk.page\/wp-content\/uploads\/2023\/10\/Termos.jpg\" alt=\"Electric water heaters&#010;\" class=\"wp-image-6223\" title=\"\" srcset=\"https:\/\/sharp-liskov.213-165-74-80.plesk.page\/wp-content\/uploads\/2023\/10\/Termos.jpg 545w, https:\/\/sharp-liskov.213-165-74-80.plesk.page\/wp-content\/uploads\/2023\/10\/Termos-300x300.jpg 300w, https:\/\/sharp-liskov.213-165-74-80.plesk.page\/wp-content\/uploads\/2023\/10\/Termos-150x150.jpg 150w\" sizes=\"auto, (max-width: 545px) 100vw, 545px\" \/><\/figure>\n<p>Experts estimate that, according to the criteria discussed above, <strong>electric water heaters <\/strong><strong>consume between 400 and 3000 kWh\/year<\/strong>. As you know, the price of electricity has been very volatile for some time now, which makes it difficult to make an accurate calculation. <\/p>\n\n<p>However, for reference, we can tell you that an<strong> electric water heater <\/strong>requires between \u20ac0.20 and \u20ac0.80 to heat one liter of water for a whole month. This is why it is so important to look at the <strong>energy efficiency label<\/strong> on the appliance. <\/p>\n\n<h2 class=\"wp-block-heading\">Operation of electric water heaters<\/h2>\n\n<p><strong>The operation of an electric water heater is extremely simple<\/strong>. Once installed and connected to the mains, the tank is filled with cold water. At that moment, the thermostat detects the temperature of the liquid and then proceeds to turn on the heating elements until the temperature indicated by you is reached.  <\/p>\n\n<p>Once the water temperature reaches this value, the heating elements turn off. They will only switch on again if you use hot water or if there are thermal losses. <\/p>\n\n<h2 class=\"wp-block-heading\">Energy saving strategies<\/h2>\n\n<p>As is obvious, <strong>the electric boiler will have a significant impact on your electricity bill<\/strong>. However, by following the tips we are going to give you below, you will be able to optimize its operation and reduce it considerably. Pay attention:  <\/p>\n\n<ul class=\"wp-block-list\">\n<li> <strong style=\"font-size: inherit;\">Choose a suitable location<\/strong><span style=\"font-size: inherit;\">. Do not make the mistake of installing the heater in the basement or garage for the purpose of keeping it out of sight. Currently, there are models with very nice designs that are easy to fit into the decor. In this regard, it is vitally important that it is as close as possible to the kitchen and, above all, to the bathroom. This will reduce heat transfer losses when the water passes through the pipes.    <\/span> <\/li>\n\n\n\n<li><strong style=\"font-size: inherit;\">Turn it off if you are going on a trip<\/strong><span style=\"font-size: inherit;\">. Even if it&#8217;s just a three-day getaway, it pays off. However, you should not turn it off if you are at home. <strong><a href=\"https:\/\/www.sharp-liskov.213-165-74-80.plesk.page\/calefaccion-iluminacion\/casas-eficientes\/\">home <\/a><\/strong>and have a constant need for hot water. Keep in mind that heating a large volume of cold water all at once requires more effort than doing it progressively.   <\/span><\/li>\n\n\n\n<li> <strong style=\"font-size: inherit;\">Select the temperature you need according to the time of the year.<\/strong><span style=\"font-size: inherit;\">. Obviously, in winter you will need hot water at a higher temperature (between 60 \u00b0C and 80 \u00b0C). In summer, on the other hand, you can have enough by setting the thermostat between 30 \u00b0C and 40 \u00b0C.  <\/span> <\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">How to find an efficient electric water heater<\/h2>\n\n<p>This is all you need to know about the<strong> energy consumption of an electric water heater<\/strong>.
