What if you take away the tank, though?<\/p>\n<p>Maybe you&#8217;re scratching your head&#8211;if you&#8217;ve never actually seen a tankless system in action, this is understandable. But it&#8217;s just what it sounds like! It&#8217;s a water heater that does not require the use of a tank holding gallons of hot water. It&#8217;s a great piece of technology with a number of benefits.<\/p>\n<h2>What makes a tankless water heater a smart upgrade?<\/h2>\n<p><span style=\"font-weight: 400;\">A tankless water heater heats water only when needed, reducing energy use by up to 50% compared to traditional tanks. It saves space, lasts longer, and provides a continuous hot water supply. Proper installation and regular maintenance are essential to ensure efficiency and long-term performance.<\/span><\/p>\n<p>Read on to learn what these benefits are!<\/p>\n<p><!--more--><\/p>\n<h2>They&#8217;re Energy Efficient<\/h2>\n<p>Instead of using a storage tank of hot water that can suffer from standby heat loss, tankless systems work &#8220;on demand&#8221; meaning their heat exchangers don&#8217;t come on until there&#8217;s a demand for such from a plumbing fixture or appliance.<\/p>\n<p>Since they do not need to constantly keep gallons of water at a certain temperature, they wind up using about 30-50% less energy than a standard tank water heater. This means you&#8217;re paying far less for the same comfort!<\/p>\n<h2>They Take Up Less Space<\/h2>\n<p>Without the big, multi-gallon tank, your tankless water heater will use up a lot less space than a conventional storage tank system. This means more space for you to use in your garage or basement.<\/p>\n<h2>There Are Resolutions to Their Limitations<\/h2>\n<p>Folk often do see one limitation of a tankless water heater, and that&#8217;s when there is too large of a demand for hot water all at once. Meaning, you may have two family members taking a shower, while trying to run your dishwasher and your clothes washer all at once. This might not be a problem for a large tank water heater, but it can overwhelm a tankless system.<\/p>\n<p>Fortunately, you can overcome this by having a second tankless system installed or even a smaller tank water heater that is assigned to one or two specific plumbing appliances. <span style=\"font-weight: 400;\">If you want your system to last and perform well long-term,\u00a0<\/span><a href=\"https:\/\/www.performanceplumbinginc.com\/blog\/water-heater-service\/do-tankless-water-heaters-need-maintenance-2\/?utm_source=chatgpt.com\"><span style=\"font-weight: 400;\">tankless water heaters require regular care<\/span><\/a><span style=\"font-weight: 400;\">, especially in areas with hard water.<\/span><\/p>\n<h2>They Should Be Professionally Installed<\/h2>\n<p>Tankless water heaters can use either only electricity or electricity and natural gas. But either way, dealing with electrical wiring\u00a0<em>and\u00a0<\/em>dealing with gas should always be left to trained, experienced, and properly licensed professionals.<\/p>\n<h2>They Do Need Maintenance!<\/h2>\n<p>Most folks know that a standard tank water heater needs routine professional maintenance. But did you know that a tankless system needs maintenance too? It can suffer from a problem known as\u00a0<em>scaling,\u00a0<\/em>when hard water minerals like calcium and magnesium harden and get stuck on the heat exchangers and other components of the tankless system. This is a natural problem, but still one that needs to be addressed.
