How Do I Know If I Need Tankless Water Heater Repair or Replacement?

Worried you might need emergency tankless water heater services? These common problems may indicate it’s time for repairs or replacement:

Inconsistent water temperature

If you’ve noticed issues with water temperature, it may indicate an issue with an internal component such as the heating element.

Leaks

Water on or around your tankless water heater can mean a leak in the system. This may be due to an internal component malfunction, a loose connection, or physical damage that needs to be patched up and resealed.

Loud noises

Tankless water heaters typically have fairly quiet operation, so loud noises are often a sign of an issue. A broken fan, loose part, or buildup of sediment from hard water are common causes of unusual water heater noises.

Age of the system

Tankless water heaters are extremely durable and may last more than 20 years with good maintenance. However, even the best models will eventually show signs of wear. If your tankless water heater is reaching the end of its expected lifespan and requires a major repair, it may be more affordable in the long run to replace it now.

Benefits of Installing a Tankless Water Heater

Constant hot water

Unlike traditional water heaters, a tankless water heater heats your water on demand. This means a continuous supply of water, so you’ll never have to worry about the shower running cold.

Extended unit lifespan

Most traditional water heaters last between 8 to 12 years, while a tankless water heater may last more than 20. 

Energy savings

Tankless water heaters only heat the water that you need, so there’s no energy wasted maintaining the water temperature. Energy Star estimates that a tankless water heater saves a family of four $95 every year in energy efficiency.

What Size Of Tankless Hot Water Heater Do I Need? 

(diagram & mathematical information courtesy this old house)
 
The table above is how the professionals ensure your on-demand water heaters deliver enough hot water.
 
It takes a tremendous amount of energy for a tankless heater to warm cold water into hot water in just a few seconds. If demand becomes too high, you will start getting lukewarm water because your heater can keep up with it or cut back on the flow.
 
To determine if a tankless water heater will be able to meet your household’s needs, a plumber will look at the temperature of the water coming into the home, when is your household’s peak demand for hot water in gallons per minute (GPM), and the heater’s efficiency, as indicated by its Uniform Energy Factor, found in the product specs. The following are the steps a plumber must go through:
 
  1. A pro finds out how many Btus (British Thermal Units) per
    gallon a heater needs to raise the incoming water to 120 degrees.
  2. Next comes peak demand, the sum of the flow rates for
    every appliance and fixture that could be using hot water simultaneously (those
    rates are listed below). The total gets reduced by 20 percent since we
    don’t bathe or wash in 120-degree water. You could also help reduce peak
    demand by upgrading to low-flow fixtures and water-saving appliances. Or
    by holding off on the washing when the shower is in use.
  3. Calculating the total Btu output is done by plugging the
    Btus-per-gallon and peak-demand figures into the formula. If that output
    falls between two models, purchase the unit with the higher Btu rating.
    And if it exceeds 198,000 Btus, the maximum for residential gas heaters,
    you’ll need two smaller tanks that work together.

Rule-of-Thumb Sizing

In case you’re not interested in doing the math. Then you can use these figures to estimate how much heater output you’ll need.

1 bathroom, 1–2 people: 140,000 Btus

2 bathrooms, 2–3 people: 190,000 Btus

3 bathrooms, 3–5 people: 380,000 Btus

Fixture flow rates:

Showerhead: 1.25–2.5 GPM

Kitchen or bath faucet: 1.5–2.2 GPM

Tub filler faucet: 4 GPM

Dishwasher: 1–2.5 GPM

Washing machine: 1.5–3 GPM

To find the actual GPM of any fixture, time how many seconds it takes to fill a bucket to a 1-quart mark. Divide that by 15, the answer will give you your fixture’s GPM.

Do Tankless Water Heaters Need Maintenance?

When you have a professional plumber install an on-demand water heater such as Nick’s Plumbing Service, we will advise you to seek an annual service. That will include cleaning or changing water and air filters, as well as checking the burner.
 
In a residential area with hard water, a vinegar flush, every 500 hours keeps scaling, also known as a mineral build-up from clogging your heat exchanger. The flush can be performed by either us or you, the homeowner.

What Can Go Wrong with My Tankless Water Heater?

A tankless water heater doesn’t have many moving parts to cause mechanical failure, but there are some symptoms to look for that can indicate a need for tankless water heater repair in Houston. The pressure of your hot water may decrease, which suggests that mineral deposits may have built up in your heat exchanger. If these clog-causing deposits are not removed with regular maintenance, they will eventually cause the heat exchanger to corrode. Corrosion of the heat exchanger will cause leaks in your tankless water heater which can then also damage the electronic components of the water heater.

Depending on the type of tankless water heater you have, gas jets and electrical contacts need to be adequately maintained to ensure consistent firing. A failure in the gas supply or electrical circuits can result in a complete loss of hot water.

What Are The Latest Tankless Advances?

With high-efficiency tankless technology continually evolving and improving, it’s hard to keep up to date on the newest advances.
 
Firstly, today’s newest tankless units are taking approximately 15 seconds to bring water up to temperature. Yet you still have to wait for it to reach your shower head or faucet. Just as you would with a traditional tank, if the distance between your heater and your fixture is greater than 50 feet, you may want to consider buying a unit that features a recirculation pump, which saves water and reduces waiting time.
 
Secondly, condensing gas heaters currently on the market can extract up 96% of a fuel’s heat. These new heaters offer a 17% improvement compared to the first-generation’s tankless units. This improvement is due to the installation of a second heat exchanger.
 
Thirdly, tankless units are now Wi-Fi compatible. This means you can adjust the temperature and monitor gas and your hot water usage on your Smartphone. Even more impressive is if you have a problem with your tank, you can identify the source and relay that information to your plumber at Nick’s.

Installing Your Tankless Unit Outside

If hanging your high-efficiency tankless water heater outside is something you’ve never considered before, there are several advantages of installing a heater outdoors, if your climate and local codes permit can save you space. It is one less appliance you have to find room for inside. The built-in exhaust vent eliminates the need to cut a large hole through your house’s side by installing your high-efficiency outside. There is tremendous ease of access. Just think, if a plumber needed to get to it for a service call, you wouldn’t need to worry if you were home or not.  They would only require access to the side of your home.
 
There may be a few drawbacks to having your high-efficiency water heater located outside your home. You may be required to seek formal permission from your local building department. Additionally, if you don’t live in a warm climate, having exposed water pipes may mean you’ll have to insulate or wrap them to avoid them from freezing.
