Tankless Water Heater Repair vs. Replacement

NexGen Tankless Water Heater Repair vs. Replacement

In many cases, tankless water heater repair can resolve an equipment problem. However, replacing the unit may be the better solution, depending on the issue and age of the system. NexGen is a leading provider of tankless water heater services in Southern California. Using our knowledge and expertise, we’ll help you weigh the decision to repair or replace a tankless system by considering the following questions.

How Old Is Your Water Heater?

Tankless water heaters can last 20 years or more. But should you use one until its very last breath? This often requires spending money on repairs that can go towards purchasing a new unit. 

While some repairs aren’t that expensive, there are a few considerations. For example, if comparable models are more efficient or the warranty has expired, investing in a new model can save you in the long run. Replacement is often discussed when an older model requires a major repair.

What Will Repairing the Unit Cost?

The cost of repairs is a big factor, especially if the water heater was recently fixed and is likely to need additional service soon. Generally, if a repair is more than 50% of the cost of installing a new tankless water heater, consider replacing it. If a repair estimate is less than that, repairing the unit can be cost-effective if it doesn’t break down frequently or requires multiple repairs.

When Was the Last Repair?

When one part goes bad, other parts may be affected. Therefore, the unit may work less effectively even after being fixed. You may need to schedule tankless water heater repair every few months, which is costlier than taking advantage of the latest technology that can improve efficiency even more than your existing heater did when new.

Is the System Serving Its Purpose?

If the answer is no, you’ll benefit by replacing your tankless water heater rather than repairing it. Signs you need a new one include water not being warm enough, hot water running out quickly, or the unit not keeping up with demand (especially when two or more fixtures are used simultaneously).

Is the Unit Working Properly?

If there are signs something is wrong with your tankless water heater, consult a professional to weigh a repair vs. replacement decision. A noisy unit can mean there’s excessive sediment buildup or a potential mechanical failure. The most concerning noises include banging, popping, crackling, and hissing. Repairing the system may be possible if it’s serviced in time and maintained properly, but there’s always a concern that one faulty component can cause others to fail.

How Is the Water Quality?

Unless an issue with your local water supply is causing water to have a poor taste, foul odor, or cloudy or rusty appearance, the problem is likely with your water heater. Tankless water heater repair may be an option. But if the unit is severely worn or corroded, replacement is the better solution.

How Efficient Is Your Water Heater?

Any water heater that’s wasting energy should be replaced, especially since repairs can be expensive. Look for issues impacting efficiency, such as a leaky tank (which accelerates heat loss), damaged insulation (preventing the tank from retaining heat), or a malfunctioning burner assembly (your water heater will use more energy but be unable to supply enough hot water).

Are Your Water Heating Bills Increasing?

The cost of your energy bills is another way to assess how efficient your tankless water heater is. Your monthly heating costs should be lower after installing one. However, if your energy bill is increasing with no reasonable explanation, consider replacing the unit (especially if it’s been used for several years and hasn’t had annual maintenance). After all, tankless units are designed to conserve energy and save on utility costs.

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
