Benefits of Tankless Water Heaters

Water heating is the second-largest expense in the home, accounting for about 20 percent of your home energy budget. It’s no surprise homeowners are always looking for ways to maximize energy and cost savings in their homes. Investing in an energy-efficient on-demand water heater could be the key. 


Think of all the energy we've wasted with our water heaters constantly running. In a large home, it's not unusual for 75 gallons of hot water in a tank to be constantly working to maintain temperature, even while you're at work or away on vacation.


Tankless water heaters use the latest in gas technology to provide an endless supply of hot water. Heating water only when it's needed provides energy savings not found with conventional water heaters (storage tanks). We can’t complain about limitless hot water, either.


A tankless water heater also referred to as an “on-demand” unit, is designed to heat water as needed as opposed to the more traditional water heater that stores heated water. Cold water flows through the heating element – fueled by gas or electric – and then into the hot water tap of a sink or shower. 


This is different from the conventional option where water is heated and stored in a tank. The conventional heater uses more energy because of this need for hot water storage – it must heat and store the hot water regularly. A tankless system only heats water as it is needed – whenever a hot water tap is opened.


Watch what goes down the drains.  This is another one of our money saving plumbing tips because it minimizes the incidence of clogging. 


Backed up water is not only a nuisance, it puts pressure and stress on your waste water pipes. This in turn shortens their lifespan. 


The Benefits of Tankless Water Heaters - How It Works

When you turn on the hot water tap, cold water is drawn through a pipe into the unit and heated either by an electric heating element or a gas burner. The hot water never runs out! 


It is good to note that while you enjoy endless hot water, the flow rate may be more limited compared to what you’re used to.  Tankless water heaters typically deliver hot water at a rate of 2 - 5 gallons per minute. Gas-fired models will generally have higher flow rates than electric models.


Keep away from chemical drain cleaners. While they temporarily get rid of the backed up water, they will also damage your pipes.

There are two basic types of tankless water heaters - small units that are usually installed right at or near the point-of-use and larger ones that are capable of serving an entire house. 


The smaller models can reduce or eliminate heat losses through piping (in addition to eliminating standby losses from a tank), but multiple units are usually needed to serve an entire house. They can be very useful for supplementing a regular water heater for a bathroom or other point-of-use located far from the main water heater.


Larger, "whole house" tankless water heaters can provide hot water for multiple points-of-use in the home. While these units eliminate the heat losses from a storage tank, there will still be some losses through the hot water piping unless it is insulated.

The Benefits of Tankless Water Heaters


Without question, tankless water heaters offer numerous advantages. Many homeowners are experiencing the advantages of tankless water heaters over traditional tank units. 


If you are in the market for a water heater it’s important that you understand why a tankless water heater may be a wise choice for your home. Tankless water heater benefits include the following considerations:



Tankless units run far more efficiently and use less energy than a tank unit. Since they use less water and run more efficiently, you’ll have more money in your pocket each month. 


It is estimated that the average tankless water heater helps you save up to 30% annually on heating costs. Tankless water heating units operate only when there is a demand for hot water, so they can virtually eliminate standby losses - energy wasted when hot water cools down in long pipe runs or while it's sitting in the storage tank. 


High-efficiency tankless systems are built to use 10 to 50 percent less energy than standard water heaters, making operating costs lower as well.



By providing hot water immediately where it is used, tankless water heaters waste less water. You don't need to let the water run as you wait for hot water to reach a remote faucet. If the unit is sized properly, it can effortlessly deliver a continuous supply of water at preset temperature levels. 


This could be as much as 5 to 7 gallons of hot water per minute. They simply never run out of the water. A tankless water heater can provide unlimited hot water as long as it is operating within its capacity. 


If you have more than 4 family members in your home, chances are the battle for hot water rages on. Trying to fit everybody’s schedule in the morning is nearly impossible without somebody ending up with cold water. A tankless water heater solves that problem instantly. 


Tankless systems do not rely on reserved hot water in a tank, but rather heat the water instantly as it passes through the unit, therefore there is always hot water at your disposal. Run the dishwasher, washing machine, and take a shower at the same time.



Another area in which an on-demand water heater scores high is safety. Their safety is due to the fact that they only operate when warm water is required. This really is unlike the storage type units which are almost permanently on. 


The most recent models include monitoring systems that provide details about water pressure and flow. In the case of system failure, the machine instantly turns off the heater. Digital temperature control at the touch of a button can be set to exact user-specified temperatures using a digital controller.


There's no possibility of flooding due to a ruptured tank. They also eliminate the risk of tank leaks and water damage.


As a tank heater gets older the reserve that sits stagnant in a storage tank for extended periods of time can rust and create contamination in the water. This problem is instantly solved with tankless heaters. With tankless systems, you get clean water that is safer to drink and bathe with. With a tankless system, water is never held within the confines of a water heater, resulting in a cleaner supply for your home.


Smaller Storage Space

Going tankless can increase storage options and free up space for other necessities in your home. Traditional water heaters holding 40-60 gallons can be around 5 feet tall and 2 feet wide. A tankless water heater will only take up the space equivalent to a home computer. 


Tankless water heaters are about 1/5 the size of a traditional tank unit. They can generally be mounted on the wall and connected to your water. Because they are safer than tank heaters, they can be placed in areas that are recommended to keep your tank heater away from. 


Not only do tankless water heaters take up less space, they can even be installed on walls or outdoors with an anti-freeze kit. Smaller units can be installed under cabinets or in a closet, closer to the point of use.


Greater Value for the Money

The lifespan of a tankless water heater is typically longer than any other available water-heating option for the home, including storage tanks, heat pumps and solar-powered heaters. A tankless unit can last up to twice as long as a conventional storage type water heater, saving on replacement costs. 


A traditional tank water heater carries a 6-10 year warranty and lasts up to a decade. By comparison, a tankless unit can have a 10-15 years warranty and last up to two decades. They’re a much greater investment in the long run. With this in mind, a tankless unit instantly adds value to your home.


Most tankless units come with a federal tax rebate. Depending upon in which city you live in you could be eligible for rebates and financing with approval for choosing a high-efficiency water heater. Electric models don't produce greenhouse gases.

Water Heater Costs

Benefits of Tankless Water Heaters Happy

The initial cost of a tankless water heater system may seem high compared to installing or replacing a conventional water heater. There are also costs that come with the installation. Necessary piping can be pricey. 


Keep in mind that tankless water heating units need good venting which can be costly.  In areas where there is hard water, a water softener must be installed so you won’t ruin the water heater. You will need a skilled plumber to do the job perfectly. 

Despite the higher initial costs, tankless system parts can easily be replaced. This helps extend use for many years beyond expectations. Tankless water heaters also lower energy costs, so the savings benefit adds up with each year of use. 


Regular maintenance increases the length of life for tankless water heaters. Maintenance is recommended at least once each year. Tankless water heaters may cost more than a traditional model to install, but the long-term savings could provide even greater value to your home.
