Better known as instantaneous water heater or tankless water heater, emergency hot water heaters have gathered a good amount of attention these days due to the energy saving benefits they offer. Heating the entire tank full of water and storing it sounds wasteful, especially if your hot water needs are not too high. Tankless heaters, however, seem to be energy efficient. They heat water as and when you need and as much as you need. However, these heaters are not meant for everyone. If you have been hearing a lot about them and want to replace your existing system with this, contact us. We will evaluate your hot water needs and only then, we will be able to tell you if the replacement is worth considering.

Meanwhile, lets discuss if they actually help you save electricity or if it’s just a hype.

Benefits of emergency hot water heaters

  • The most important benefit for which they have received a lot of attention is that they help you save energy. You may have to pay a high upfront cost but they CAN minimize your operational cost down the line. You will not be spending energy for heating a tank full of water on standby. You will not be heating and reheating a lot of water on a continuous basis, to maintain a specific water temperature. Instead, you will heat up just as much water as you need and whenever you need.
  • Tankless water heaters are found to last longer than their counterparts, subjected to proper maintenance, appropriate usage, and many other factors. This is because they do not work continuously like the tank heaters. You turn them off when you don’t need them and therefore, the heating element and other parts do not require any frequent replacement or repair.
  • Another big advantage with tankless heaters is that they are very compact as compared to traditional water heaters. Tank heaters are too bulky and require a lot of space. Tankless varieties are so small that you can install them under the cabinet or in the closets.
  • They never run out of hot water, as long as you provide a continuous supply of electricity.

Drawbacks of instantaneous hot water systems

  • A tank heater can heat and store up to 60 gallons and even more water. You can simultaneously use multiple showers, appliances, and faucets without running out of hot water. Modern heaters quickly heat up the additional supply and therefore, you will get assured hot water. However, the output of an emergency hot water heater is very limited. It can supply you just a few gallons of hot water at a time. If you have a large family where almost everyone takes showers at the same time or uses multiple appliances, faucets, and showers together, tankless varieties may not be for you.
  • Emergency water heaters require instantaneous energy. This means that you will not get hot water if you are facing electricity problems or gas problems. This isn’t a major issue but we thought of mentioning this in our blog so that you can make an informed decision.

After weighing the pros and cons, we conclude that emergency hot water heaters are not just hype but, at the same time, they are not meant for everyone. The choice between tank and tankless varieties depends on many factors, including your usage.
