Professional Water Heater Installation for Your Home

Ready to replace an aging water heater or upgrade to a more efficient system? Ehret installs traditional and tankless water heaters for homeowners throughout the Metro East.

Reliable Hot Water Starts With the Right Water Heater

Your water heater is responsible for providing hot water for showers, laundry, dishes, cleaning, and countless other daily tasks. When it’s time for a new system, choosing the right water heater—and having it installed properly—can make a difference in comfort, efficiency, and long-term reliability.

Ehret provides professional water heater installation and replacement throughout the Metro East. Our experienced plumbers can evaluate your household’s hot water needs, discuss available options, and install a system that is properly sized for your home.

Whether you’re replacing an older water heater or considering an upgrade to a tankless system, we’ll help you understand your options before installation begins.

Find the Right Water Heater for Your Home

Every household uses hot water differently. Ehret can help you select a system based on your home, family size, hot water demand, available space, and other important factors.

Traditional Tank Water Heaters

Traditional water heaters keep a supply of hot water stored and ready for use. They remain a practical choice for many households and are available in different capacities to accommodate different levels of hot water demand.

Tankless Water Heaters

Tankless water heaters heat water as it is needed instead of storing it in a tank. They can provide a compact installation, improved energy efficiency, and a continuous supply of hot water when properly sized for the home.

Water Heater Replacement

If your existing water heater is nearing the end of its useful life or experiencing repeated problems, Ehret can remove the old equipment and professionally install a new system.

Gas Water Heaters

Ehret can install gas water heaters and ensure the new equipment is properly connected and configured for safe, reliable operation.

Electric Water Heaters

For homes using electric water heating, we can install an appropriately sized electric water heater based on your household’s hot water needs.

Water Heater Upgrades

Replacing your water heater can be an opportunity to consider a different capacity, improved efficiency, or a tankless system. We’ll explain the available options so you can choose what makes sense for your home.

Should You Replace Your Water Heater?

A water heater doesn’t necessarily need to stop working completely before replacement should be considered. An older or increasingly unreliable unit may give you several warning signs.

Consider talking with Ehret about replacement if:

  • Your water heater is approaching or beyond its expected service life
  • Repairs are becoming more frequent
  • The tank itself is leaking
  • You regularly run out of hot water
  • Water temperatures are increasingly inconsistent
  • You notice rust or corrosion around the unit
  • The system no longer meets your household’s hot water needs
  • You’re interested in upgrading to a tankless water heater

If you’re unsure whether replacement is necessary, Ehret can inspect your current water heater first. A repair may still be possible, and we can explain whether repairing or replacing the system makes more sense.

What Size Water Heater Does Your Home Need?

Choosing a water heater isn’t simply a matter of replacing the old unit with whatever fits in the same space. The right system should be able to keep up with your household’s typical hot water demand without being unnecessarily oversized.

Factors that can influence your choice include:

  • Number of people in the household
  • Typical hot water usage
  • Number of bathrooms
  • Simultaneous hot water demands
  • Available fuel source
  • Space available for the equipment
  • Energy-efficiency goals
  • Whether you prefer a tank or tankless system

Ehret can evaluate these factors and recommend appropriate options for your home rather than leaving you to determine sizing on your own.

Traditional or Tankless: Which Is Right for You?

Water Heater Tank

Traditional Tank Water Heater

A traditional system stores heated water in an insulated tank, keeping it available until you need it.
A traditional water heater may be a good fit if you want:
  • A familiar and straightforward system
  • Multiple capacity options
  • A typically lower initial equipment cost
  • A direct replacement for an existing tank system
Water Heater Tankless

Tankless Water Heater

A tankless system heats water on demand as it passes through the equipment rather than continuously maintaining a stored supply.
A tankless water heater may be a good fit if you want:
  • Hot water produced on demand
  • Greater energy efficiency potential
  • A compact system that doesn't require a large storage tank
  • Longer equipment life potential with proper maintenance
  • An upgrade from a traditional tank-style system

Your Water Heater Is Only as Good as Its Installation

Proper installation is important for the safety, performance, efficiency, and longevity of your new water heater.

A professional installation helps ensure that the equipment is properly sized, plumbing connections are secure, applicable gas or electrical connections are handled correctly, and the system is configured for reliable operation.

Ehret’s experienced plumbers handle the installation from start to finish so you can feel confident that your new water heater is ready to serve your household.

Protect Your New Water Heater With Regular Maintenance

Installing a new water heater is an investment in your home. Routine maintenance can help protect that investment by keeping equipment operating properly and identifying developing problems before they become more significant.

Water Heater Installation FAQs

Age, repeated repairs, leaking, corrosion, inconsistent temperatures, and an inability to meet your household’s hot water needs can all be reasons to consider replacement. Ehret can inspect your existing system and help you determine whether repair or replacement is appropriate.

 

Traditional tank-style water heaters commonly last around 8–12 years, although actual lifespan depends on factors such as usage, water quality, maintenance, and the equipment itself. An older unit does not automatically require replacement, but increasing repair needs can be a sign that it’s worth considering.

Both can be good choices depending on your home. Traditional tanks offer a familiar approach with stored hot water, while tankless systems heat water on demand and can offer efficiency and space-saving benefits. Ehret can help you compare the options based on your household.

In many homes, converting from a traditional tank to a tankless water heater may be possible. However, installation requirements can differ, so the home and existing plumbing and utilities should be evaluated before choosing a system.

The right size depends on factors such as household size and typical hot water demand. Rather than choosing based solely on your existing water heater, Ehret can help determine an appropriate capacity for your household.

When replacing an existing water heater, Ehret can handle removal of the old equipment as part of the installation process. We can explain what is included when discussing your replacement.

We came home from an out-of-state funeral to find our A/C not working. We called Ehret at 7:30 this morning and spoke to an actual person. She was very personable and told us they would be out this morning between 9 and 11. The technician actually arrived before 9. He gave fast, friendly service and had our A/C running within a few minutes.

Nick was kind, professional and knowledgeable. He repaired my showers quickly. He did not talk down to me as others have. If I could I would give him 10 stars.
