How does a tankless water heater work?

Unlike conventional water heaters that store heated water in a reservoir so that hot water is available when needed, tankless water heaters only begin heating the water upon demand. Their heating elements are designed to heat cold water in an instant. This is why they never run out of supply of hot water.

They can be powered by gas or electricity. Gas-powered tankless water heaters usually have a higher water flow rate than electric ones. The average flow rate is two to five gallons per minute. This is where its limitations lie, especially when you have a whole house model and several water outlets are used simultaneously. This is why it is important to install a water heater of the right size that should match your household's demand for hot water.

Other than this issue, tankless water heaters are seen as more energy and cost-efficient than their conventional counterpart.

Advantages of a Tankless Water Heater

Using a tankless water heater offers many benefits such as the following.

Energy Efficiency 

No heat is lost during storage or while on standby. They also have a lower operational cost and consume less energy since they only heat water when there's a demand for it.

You can also install them right next to your shower or faucet. This lessens the waiting time for your hot water supply and reduces heat loss from the point where water is heated to the point of use. 

Compact

These water heaters are compact. This means they won't eat up too much space in your bathroom, kitchen, or laundry area. There is no additional ventilation needed that's why you can install these units even in remote places in your home.

Value for Money

Tankless water heaters may have a higher upfront cost but they can generally last for 20 years compared to storage water heaters which have a lifespan of 10 to 15 years.

Reduced Repair Costs

When repairs are needed, their parts can easily be replaced so you don't have to spend too much on repair costs.

These are the benefits you stand to gain due to the efficiency and design of tankless water heaters. For households with a high demand for hot water, it is good to consider going tankless.

How do I care for my Stiebel Eltron water heater?

Your Stiebel Eltron water heater is a good investment and you should take good care of it to make it last longer. Here are some tips and recommendations for its maintenance.

Descaling

Scales or mineral formations can clog up your water flow. It is advised that you descale your faucet aerators and showerheads regularly to prevent buildup.

Stiebel Eltron recommends mixing a quart of Flow-Aide with 1.5 gallons of water to flush the sediments out of the hoses of your water heater. Some use vinegar solution for this job. Check your manual for the procedure.

Install a Filter or Water Softener

It is important to have your water quality tested. Some homes are serviced with hard water. This contains more minerals that can lead to sediment formation.

If you have hard water in your area, you can install a filter or water softener to prevent mineral buildup and extend the life of your water heater.

Clean or Replace the Filter Screen

Each Stiebel Eltron water heater comes with a filter screen. Check your manual to know its exact location since it varies depending on the model. They also have instructions on how to remove and put it back in place.

Dirt and minerals can also build up in this portion so it's best to have it cleaned regularly. You can use a vinegar or descaling solution. You can also buy a replacement if necessary.

Remember to shut off the circuit breaker when you perform any cleaning and maintenance on your unit. Always practice caution when handling your water heater to avoid burns, electrocution, and death.

Final Thoughts

It's important to know how to reset your Stiebel Eltron water heater. Many times, it'll save you from the hassle of calling a pro to have your water heater checked. With a simple reset, you can have your unit running in no time.
