Tankless Water Heater Myths Unlocked

tankless water heater myths debunked by Bob's Heating & Air Conditioning

When it comes to water heaters, tankless water heaters are becoming an appealing option for many homeowners. With a tankless water heater you can get better efficiency and endless hot water without the unit taking up too much space. Although there are many advantages of using these types of water heaters, there are still some misconceptions regarding their effectiveness. Read our blog to unlock the 4 major myths about tankless water heaters.

Myth #1: Tankless water heaters are more expensive to operate

Although the initial cost of a tankless water heater can be high in comparison to alternatives, tankless water heaters typically last longer and have lower operating and energy costs. In the long run, these water heaters are considerably less expensive to operate and can save your family $100 or more each year on your energy bill.  Often called on demand water heaters, they supply hot water as needed and do not store hot water that is not being used.

Myth #2:  Tankless water heaters heat water to an unsafe temperature

Tankless water heaters offer an adjustable thermostat for personalized use, so that you are able to enjoy hot water at just the right temperature for you. Like other type of heaters, tankless water heaters have a thermostat in order to prevent overheating and potential scalding.  So you don’t have to ever worry about the water getting too hot when you are taking a shower or doing the dishes.

Myth #3:  A tankless water heater does not supply enough hot water

Since a tankless water heater does not have a storage tank that means that there is no shortage of hot water. Tankless water heaters deliver a constant supply of hot water, so there is no need to wait for it to fill up with enough hot water. Water is heated as it passes over a heating element to an outlet and as long as you need hot water, you will receive it.  Tankless water heaters are designed to supply hot water for the entire family and some have a capacity of up to 9.4 gallons of hot water per minute.

Myth #4:  All tankless water heaters are the same

Throughout the years, tankless water heaters have become a more reliable and cost effective option for many homeowners. There are different brands available for tankless water heaters and some are better than others for certain applications. There are models that offer easier installation, more energy efficiency and are more affordable. One of the most important things to consider when choosing a new water heater is to make sure the quality of installation is high. Reliable and good performance depends on both the brand of the water heater as well as the company that installed it.

4 Signs You May Need a New Water Heater















Like most major appliances in your home, water heaters break down after a period of time. Ideally it would be best to replace your water heater before it completely stops working or starts causing water damage to your home from large leaks. However, most people have no idea that their water heater is about to fail and unfortunately run into big problems as a result.

Here are four major indicators that your water heater might need to be replaced:

1. Rusty or Muddy Water

If you turn on your hot water and notice that the water coming out from the faucet is a rusty color instead of clear, this is a tell-tale sign that the inside of the water heater tank is starting to corrode. When a water heater starts to deteriorate, usually rust develops around the tank seams, the temperature and pressure relief valve, the water supply lines, or the drain valve. If you notice muddy or sandy water from your faucet, that could be a sign of sediment build up in your tank.

2. Rumbling Noises

It is important to pay attention to the noises that your water heater makes. While some sound is normal as the water heats, watch out for loud cracks and pops. Most noise issues are caused by sediment build up inside the water tank. As the sediment is heated and reheated, it eventually hardens. When the hardened sediment comes in contact with the heating element, it makes a lot of noise as it burns the sediment away. These sounds indicate an interaction between the heating elements inside the heater and the scale and mineral deposits built up on them.

 3. Water Around the Water Heater

If you notice standing water or leaking water around the water heater, it is best to call a professional right away since that is an indication of internal failure in the water heater. There is no quick and easy fix for a leaking hot water tank and you will most likely need to replace your water heater as soon as possible, in order to prevent flooding or further damage to your home. Make sure to disconnect electricity or turn off the gas unit and let the water cool down before attempting to remove and replace the water heater.

4. Age of Your Water Heater

How long has it been since you last replaced your water heater? Most water heaters last an average of 10 years. If yours is older or you are not sure when it was last replaced, it may be nearing the end of its life. It is important to know the age of your water heater and you can find out the age by looking at the serial number on the manufacturer’s sticker on the upper portion of the water heater.
