Top 6 Reasons To Get A Tankless Water Heater

Tankless water heaters heat water directly without using a storage tank. When a hot water tap is turned on, cold water flows through a pipe to the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters provide a constant supply of hot water. In this regard, what are the advantages and disadvantages of a tankless water heater? So, without further ado, let’s dive into this blog and learn some of the things everyone should know about tankless water heaters.

Advantages and disadvantages


They can virtually eliminate standby losses- the energy wasted when hot water cools in long pipe runs or while it sits in the storage tank. Tankless water heaters waste less water by providing hot water immediately where it is needed. Second, is a tankless water heater worth it?

According to the U.S. Department of Energy, a tankless water heater is more efficient and uses less energy than a conventional water heater, resulting in an annual savings of $25 to $107. If your hot water usage is low (less than 41 gallons per day), a tankless water heater will be 24% to 34% more efficient.

Tankless water heaters produce an endless supply of hot water, take up less space, have a lower risk of leaks, are safer, and have a significantly longer lifespan on average. The main disadvantage of tankless water heaters is that their initial cost (unit and installation) is significantly higher than tank water heaters.

1. How hot is the water in a tankless water heater?

Answer: You will need to raise the temperature of the incoming water from 40 degrees to 105. You will need to be able to heat at least 5.2 gallons of water, so you will need a tankless water heater that can produce at least a 60-degree temperature rise at 5.2 gallons per minute.

2. Running out of hot water with a tankless water heater?

Since tankless water heaters heat water as it flows, you’ll never run out of hot water. Tankless heaters also last five to ten years longer than a storage tank model. Electric models don’t produce greenhouse gases, and there’s no possibility of flooding due to a broken tank.

3. What size tankless water heater do I need for a family of 5?

Like, a hot water tank for 5 people will require at least a 60-gallon tank. Since tankless water heaters provide continuous hot water, you don’t have to worry about capacity but rather think in terms of water flow. Gallons per minute (GPM) is the key when it comes to sizing tankless water heaters.

4. Is it worth it to buy an electric tankless water heater?

Installing a Classic Shower

The U.S. Department of Energy estimates that gas tankless water heaters save an average of $108 in energy costs per year compared to their traditional tank counterparts, while electric tankless water heaters save $44 per year. Rewiring your home can easily add up to $5,000 to the cost of installing a tankless water heater.

5. Which is better tankless or tanked?

According to, “For homes that use 41 gallons or less of hot water per day, on-demand (or tankless) water heaters can be 24% to 34% more energy efficient than conventional storage tank water heaters.” Tankless water heaters (if gas-fired) will save homeowners more than $100 a year the longer they stay in service.

6. Which is the best gas or electric tankless water heater?

While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency typically peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. On top of that, electric tankless water heaters cost significantly less than most gas tankless models.
