How Much Does Tankless Water Heating Cost?

In both residential houses and business buildings, water heaters are an essential component of the plumbing systems. Due to their numerous advantages, consumers are switching to tankless units. 

Tankless water heater installation costs roughly between $2,500 to $4,500 nationwide. Installing a tankless whole-house gas type with a 150,000 BTU capacity costs the typical homeowner $2,811. A 240v electric tankless model installed at a single location has a low cost of $1,058 for this project. Installing an 80-gallon whole-house solar system will cost you $6,698.

Tankless Water Heater Costs

Low-end$1,058
High-end$6,698
Average Range$2,500-$4,500
National Average Cost$2,811

Tankless Water Heater Installation Cost

Depending on the brand of the heater, as well as its features and capabilities, the cost of installing a tankless water heater might vary significantly. 

For instance, the average cost of propane tankless heaters and solar-powered heaters is more than that of an ordinary electric heater. 

Although labor and material costs might vary greatly depending on where you live, it can also have a significant impact on the cost.

Fuel Type Average Unit Cost 
Electric $450 – $1,500
Natural Gas$500 – $2,000
Oil$600 – $3,000
Propane$500 – $2,000
Solar$1,000 – $4,000

Tankless Water Heater Maintenance

Tankless heaters don’t need as much maintenance or spare components as a conventional tank water heater. 

It’s crucial to routinely clean or replaces the water filter, clean the air filter (for gas systems), descale the system, and flush it to extend the performance and lifespan of your tankless water heater.

Cleaning or Replacing Water Filter

A water line filter is a common feature of tankless water heaters and guards against silt, scale, and hard water. There are several different kinds of filters; some can be cleaned and reused, while others must be changed. 

These impurities not only have the potential to accumulate and harm the water heater but also to spread throughout the rest of your plumbing system, including pipes, faucets, and appliances.   

To make sure you’re servicing your system correctly, see the user handbook for your tankless water heater. You can add a water filter to your tankless water heater if it doesn’t already have one to enhance the water’s quality and safeguard your plumbing.

Flushing the System

At least once a year, the hot water heater needs to be flushed. Minerals build up inside the water heater throughout the course of the year. This may accumulate more quickly if your water source is hard. Mineral buildups can harm your unit’s heat exchanger. 

Moreover, the tank’s efficiency could degrade, which would result in a rise in your monthly energy costs. Your tankless hot water heater’s lifespan can be significantly shortened if you don’t flush it. Unfortunately, your guarantee does not extend to harm brought on by mineral buildup.

Cleaning Air Filter

Your tankless water heater has an air filter that needs to be cleaned on a regular basis. Clean this filter by removing it from the water heater.

The next step is to clean it with a soapy water solution using a gentle brush. To guarantee optimal airflow, be sure to properly clean it. Rinse thoroughly, and after it has dried fully, place it back in the water heater.

Need to Clean the Water Tank

To make sure that no dust or other debris accumulates on the tank’s outside, it is a good idea to clean it down. 

Before doing this, turn off the water and electrical supplies. Clean the tank and the area surrounding it. Dust and other material can accumulate inside the water heater, which could lead to problems.

What are the most reliable tankless water heater brands? 

Before buying a water heater, do extensive research on it. A few well-known tankless water heater manufacturers have reliable goods on the market right now. Start your search off right by using this list.

Tankless Water Heater vs Tank Water Heater

Tank-style and tankless water heaters are the two primary types of water heaters that are available. To heat water and provide the hot water your family needs for numerous activities around your home, each works in its own unique way. 

However, it may be confusing which one will be perfect for you. So, let’s explore it. 

Tank Water Heater

Since tank storage water heaters have been around for a while and are a common option in homes, they are the type of water heater that homeowners are most likely to be familiar with. 

Although this older technology has been the norm in homes for decades, you may also hear this type of water heater referred to as a conventional or classic tank water heater.

Storage water heaters are tank-style heaters that heat water and then store it for later use. These water heaters are available in a variety of capacities, with tanks that typically hold 30 to 50 gallons. 

Moreover, your household’s size and hot water usage will determine the size you need. Tank water heaters can be electric types or ones that run on natural gas. 

For instance, a 40-gallon hot water tank is not small equipment, so installing tank water heaters requires considerable floor space. These water heaters are frequently put in basements, garages, utility rooms, or even right in your bathroom.

Tankless Water Heater

An energy-efficient replacement for tank water heaters and related issues with standby heat loss is the more recent invention of tankless water heaters. 

Since they don’t need a tank to store heated water, as you would have surmised from their name. Where does the hot water originate? Since they don’t pre-heat and store water in reserve, tankless water heaters operate differently from tank water heating systems. 

They only heat water when it is actually needed by your hot water faucet and appliances. The tankless water heater heats water at the desired temperature and delivers hot water to the desired outlet as soon as a hot water tap activates, signaling the need for hot water.

Even though they heat water as it is needed rather than preheating it for storage, tankless water heaters are often referred to as on-demand water heaters. Tankless water heaters need electricity or natural gas to operate, just as tank types.

Thus, you have definitely realized that it will be a wise decision to go for a tankless water heater for your living space.   

What Are The Different Types Of Tankless Water Heaters?

Tankless water heaters come in three types: Non-condensing, Condensing, and Hybrid.

Non-condensing

Heat exchangers are used by non-condensing tankless water heaters to warm the water. A hot exhaust is produced as a result, and it must be vented outside the house. 

Budgeting for non-condensing units can be more challenging because they require an expensive vent to be constructed.

Condensing

Heat exchangers are numerous in condensing water heaters. They are made to collect the first heat exchanger’s exhaust and use it to warm the water even further. 

Condensing tankless water heaters are therefore more effective than their non-condensing competitors.

Hybrid

All other tankless water heaters are not the same as hybrid models. Since they have a small tank but consume a lot less energy than conventional tank-style water heaters, they are known as hybrids. Hybrids transfer heat from the ambient air to the tank.

They are not suitable for everyone, despite being even more efficient than conventional non-condensing and condensing tankless water heaters. 

Even more expensive to buy than conventional tankless heaters, these ones can be. Additionally, for them to work, the area around the water heater must be open.

According to the US Department of Energy

“You may save around 24% to 34% energy by installing tankless water heaters rather than conventional tank water heaters. The longer tankless water heaters are in use, the more money homeowners will save (assuming they are powered by gas). On the other hand, electric tankless water heaters continue to save homeowners about $44 annually.”
