What is a Tankless water heater?

Tankless water heaters have gained a lot of popularity in recent years. Some people prefer these types of water heaters to tank heaters because they are significantly smaller and therefore, do not take up as much space. Tankless water heaters are extremely useful in times when there is not enough water available. They can save homeowners a lot of money because they do not need to heat the entire building. A tankless water heater only requires a small amount of water, so it can be installed in a smaller space. They are also very energy efficient, and they heat the water quickly. When the water is turned on, it is immediately ready for hot water usage. The system does not have to heat a large tank full of water.

Why Should You Invest in a Tankless Water Heater?

Tankless water heaters are great for homeowners who want to save space and money since they are virtually unattended. Most tankless water heaters do not need to be installed manually and can be installed by the heating technician. With a tankless water heater, you do not have to worry about the risk of water freezing, because the heater takes care of that for you! It is also a good idea to get a tankless water heater because it uses a lot less energy than a conventional water heater, which can be a huge help in cutting down the amount of electricity you use. Tankless water heaters are also a good option for those who are short on space or want to install a tankless water heater in a particular area of the home since it is not as big of a challenge.

What are the Dangers of Tankless Water Heaters?

If you have ever owned a gas water heater, you’re probably familiar with the risks associated with them: exploding valves, leaking gas, improper maintenance, weak or faulty insulation, and a lot of surprise repair bills. On the other hand, tankless water heaters don’t rely on a built-in supply of gas or hot water. They can make for an extremely convenient way to heat water, but they are no less dangerous. They can use more electricity than their gas counterparts, and some tankless water heaters can also break down easily and cost you a lot of money in the process. What does this mean for you and your family? It means you should make sure that you get a reliable, safe tankless water heater for your home.

The 3 Dangers of Tankless Water Heaters

In addition to concerns about the ease of installation and that they seem to be less expensive than traditional tankless water heaters, there are a few things you should look out for:

  • When water heats, it can expand. When water expands, it can cause leaks. A broken water heater can cost up to $7,000 or more to fix. The water heater will leak and be stopped only by getting a plumber to fix it. Leaks from a tankless water heater are not easy to spot. However, they can be easily prevented.
  • Overheating –  Sometimes the tankless water heaters can overheat, which can cause danger of explosion. To prevent that check your water heater temperature often, and unplug it if it’s too high.
  • Electrical fires, and gas poisoning are things you should consider,before buying a tankless water heater.

Installation and operation of boilers without a tank:

As with any equipment, a tankless water heater should be installed before it is used. The pipe needs to be clean and free of debris so that it’s not crushed during installation. You should also ensure that any necessary connections are made at the highest level in the tank. While they’re easy to install, the water heater tank itself can be a dangerous part of the water heater system if not installed properly. Some models of tankless water heaters will shut down during the installation process when you add a large quantity of water to the tank. This will immediately shut down the entire water heater system, even if the tank wasn’t full. This is called a ‘tank off’ error and causes a serious safety hazard.
