In case you haven't heard of what a tankless water heater is, it is an efficient device that heats water to a specific temperature based on hot water demands. Tankless water heaters supply hot water to your home without the need to have storage tank units.

Let's look at how to install an electric tankless water heater and the gas water heaters.

How to Install Tankless Water Heater - Step By Step Process

More households have begun embracing this efficient water-saving technology, which has led to the decline of the conventional storage tank option. Because of this, the need for proper installation is now more than ever. That’s why you need proper installation guidelines.

How To Install Tankless Water Heater - Step By Step Process

It should be noted that installing a tankless water heater is technical and can be properly carried out by a professional. However, you can still do the installation yourself if you follow these tankless water heater installation instructions.

  • Shut the water and the gas supply to the tank off.
  • Drain the water out of the tank.
  • Use a gas line that is adequate to transport the gas from the meter to the heater.
  • Drill a hole near the location of the water heater. If you like, you can install your tankless water heater outside for more air combustion. It should be set up so that there is enough tankless water heater vent.
  • Run two PVC pipes through the drilled hole.
  • Join the cold water line to the water heater and connect the hot water line out of the heater.
  • Add an electrical outlet to the water heater. You may need an electrician for that.
  • If the water heater is far from your home, consider installing a crossover valve to allow the recirculation pump to keep hot water within touching distance.
  • Switch on the cold water supply, gas, and power to test the installation.

Things to Consider Before Installing a Tankless Water Heater

Before you say yes to having tankless water heaters run in your home, there are few requirements you should consider. There's quite a lot to know about installing a tankless water heater, and without adequately examining these requirements, you could create more problems, which would lead to more costs.

Things to Consider Before Installing a Tankless Water Heater

Here are a few things you should consider before installing a tankless water heater:

Initial Cost

Quality doesn't come cheap, right? This is the case with tankless water heaters. Tankless water heater installation cost can range from several hundred dollars for the small gas-powered units to thousands of dollars for high-output heaters. Compare it to the regular tank option, and you will discover that the cost of installing a tankless water heater is higher.

The type of water heater installed also contributes to the cost. Although an electric tankless water heater is less expensive than the gas counterparts, it is still not affordable. Installation is more straightforward with electric tankless water heaters, so is the maintenance. Gas tankless units are more efficient, though, as you can use them for commercial use.

Based on gas usage, gas tankless water heaters use a very high quantity compared to the tank option. The gas line you are to use, which must be adequate to supply the gas to the water heater, adds up to the huge costs.

In addition to the initial cost, you must determine the temperatures and the use patterns. What do you want to use the heated water for? How many people in your household use heated water? Tankless water heaters do not have storage tanks, so you will need the heater to maintain proper water flow to accommodate your needs.

The higher the number of users, the more you need the heater to maintain a peak hot-water flow at the desired temperature, which will contribute to the initial cost.

Multitasking

Avoid multitasking with tankless water heaters, especially if you have small units. If you want to run a larger quantity of water into your home to meet your needs, ensure you purchase larger units. First of all, consider your fixture flow rates. Your fixture flow rate will determine how large you want the tankless water heater to be.

Storage Tank Option

If you feel you can’t cope with the length of time the heater use in heating, you can purchase a storage tank. People like tankless water heaters for their lack of tanks, but that doesn't stop you from getting a storage tank option if you feel your needs aren't timely met. Storage tanks will provide backup water if you need to multitask. 

Energy-Saving

One of the reasons why people love tankless water heaters is due to their energy-saving capabilities. Tankless water heaters will save you tens to several hundreds of dollars every year, more than regular storage tanks. The cost of installing and purchasing all the equipment may seem extravagant, but you will save thousands of dollars year-on-year in the long run.

Space Saving

These days, every homeowner wants to make sure that every space in their homes is appropriately utilized, and not the other way round. If your view falls in this line, installing tankless water heaters won't be a problem as it doesn't occupy so much space in the home, unlike regular water tanks. Typical water tanks require tons of space to get installed. With a tankless water heater, you get to save some square feet for other purposes.

Repairs

Since tankless water heaters have more parts than regular tank heaters, there’s room for more repairs, which results in high repair costs. Some companies do provide warranties on their products, while others do not. In essence, you should get prepared should anything happen to your tankless water heaters.

For example, gas leaks from gas lines do occur, and when it happens, you should get a professional to repair it. The cost will depend on how many holes are spotted on the gas line.

Do more repairs translate to fewer energy savings? No, it's doesn't. The fact that you are carrying out repairs on your tankless water heater doesn't mean that you won't have enough energy savings. However, if you think otherwise, refrain from considering this factor. 

Tankless Water Heater Problems

Despite the usefulness of a tankless water heater, it has some downsides. The expensive nature of installing tankless water heaters is often a significant concern to most homeowners.

Tankless Water Heater Problems

For example, installing a gas tankless water heater is two-three times as costly as that of regular tank models. Even after the initial cost, subsequent costs are slightly expensive.

Unlike regular water tank, tankless water heaters will not produce hot water when there is a power outage - and since there is no backup storage tank (unless you have one), you will have no hot water to use when the demand arises.

Tankless Water Maintenance

Typically, you may wonder if tankless water heaters require more maintenance services than the regular storage tanks. The fact is they don't need that much maintenance. All you have to do is follow some tips.

Tankless Water Maintenance

You should service your tankless systems regularly. Check the gas or electric components and every other thing that may be wrong with the heater. This is to ensure that the water heater is performing at the optimum level.

In addition to servicing the heater, you should use a water softener. This will prevent the buildup of sediments and particles from hard water that may destroy the pipes and the system. You may think that hard water is only a problem for those with tanks, but it could affect tankless units as well, so long as the water is involved.
