Tankless Water Heater Installation, Repair & Maintenance

Thinking about switching to a tankless water heater? Already have one that needs service? Colorado Green Plumbing, Heating & Cooling provides professional tankless water heater installation, repair, and maintenance for homeowners throughout Longmont, Erie and the surrounding Front Range.

Tankless water heaters can offer several advantages, including continuous hot water, improved efficiency, and a compact design. However, they are not the right solution for every home.

Our experienced team will evaluate your household's hot water needs, review your home's existing plumbing and utility setup, and explain your options clearly. As Certified Authorized Navien Installers, we have the training and expertise to properly install and service Navien tankless water heaters while helping you determine if they're the right fit for your home.

Our goal is to help you choose the right system for your home, not simply the most expensive one.

Unlike a traditional water heater that stores hot water in a tank, a tankless water heater heats water as it is needed.

When you turn on a hot water fixture, water passes through the unit and is heated before reaching the faucet or appliance. Because the system does not rely on a storage tank, a properly sized tankless unit can provide a continuous supply of hot water.

Benefits of Tankless Water Heaters

Depending on your home and hot water usage, a tankless system may offer:

• Continuous hot water
• Improved energy efficiency
• Reduced standby energy loss
• A compact, space-saving design
• A longer potential service life than many traditional tank models
• Consistent hot water when the system is properly sized
• Less risk of a large storage tank leaking

The benefits will vary based on the system, installation, household demand, and maintenance.

Navien or Rinnai: Which Is Better?

Both Navien and Rinnai manufacture quality tankless water heaters. The best choice depends on factors such as:

• Your household’s hot water demand
• Available installation space
• Existing gas service
• Venting requirements
• Desired features
• Budget
• Maintenance expectations

We will explain the differences between the available systems and help you select the model that best fits your home.

Professional Tankless Water Heater Installation

A tankless system must be correctly sized and professionally installed to perform as expected.

Switching from a traditional tank to a tankless water heater may require changes to:

• Gas lines
• Electrical connections
• Water lines
• Venting
• Drainage or condensate disposal
• Recirculation piping
• The location of the unit

These requirements can increase the installation cost compared with a standard tank replacement.

Before installation, we will evaluate the property and explain any required modifications. Unexpected site conditions or code requirements may affect the final project price.

Tankless Water Heater Maintenance

Tankless water heaters require ongoing maintenance, especially in areas with mineral-rich water.

Maintenance may include:

• Flushing and descaling the heat exchanger
• Checking filters
• Inspecting venting
• Testing system performance
• Reviewing stored error codes
• Checking water, gas, and electrical connections

The appropriate maintenance schedule depends on your water quality, usage, and the manufacturer’s recommendations.

Frequently Asked Questions

Do tankless water heaters provide endless hot water?

A properly sized tankless water heater can provide continuous hot water. However, every system has a maximum flow capacity. If several showers, faucets, or appliances are using hot water at the same time, the household demand may exceed the unit’s capacity.

Are tankless water heaters more efficient?

Tankless systems can reduce standby energy loss because they do not continuously maintain a full tank of hot water. Actual energy savings depend on household usage, system efficiency, utility rates, and installation conditions.

Do tankless water heaters work well in Colorado?

They can, but proper sizing is critical. Colorado’s colder incoming groundwater means the system must work harder to raise the water to the desired temperature. A professional evaluation helps determine whether a tankless unit can provide the flow rate your household requires.

Can a tankless water heater be installed outside?

For Colorado homes, we generally recommend indoor installations because freezing temperatures can create additional risks for outdoor plumbing and equipment.

How often does a tankless water heater need maintenance?

Many tankless systems should be inspected and flushed approximately once a year, although homes with hard water or heavier usage may need more frequent service. Manufacturer recommendations should also be followed.

How long does a tankless water heater last?

A well-maintained tankless water heater may last longer than many traditional tank models. Actual lifespan depends on water quality, installation, maintenance, usage, and the specific equipment.

Do you repair Navien and Rinnai tankless water heaters?

Yes. We provide diagnostics, repair, maintenance, and replacement services for Navien and Rinnai tankless systems.
