Why Choose a Tankless Water Heater?

Tankless water heaters (also known as on-demand water heaters) provide hot water only when needed — which means no energy waste from storing hot water all day and night. Instead, cold water flows through a heat exchanger when you turn on a faucet, instantly heating water to your desired temperature.

Key benefits include:

  • Endless hot water for showers, laundry, and dishes
  • Reduced energy bills compared to storage tank systems
  • Compact, wall-mounted units that save floor space
  • Longer lifespan (up to 20 years with maintenance)
  • Cleaner water with no rust or sediment from old tanks

A tankless system is a smart investment for Denver-area homeowners looking to improve comfort while cutting energy costs — especially in homes with multiple bathrooms or high hot water usage.

What Our Customers Say

Tankless Water Heater Replacement

If your existing tankless system is outdated, inefficient, or beyond repair, we'll remove and replace it with a modern, high-efficiency model. We'll ensure a seamless transition with minimal downtime, and handle:

  • Safe removal and disposal of old units
  • Gas and plumbing reconnections
  • Upgrade of exhaust systems or venting as needed
  • System testing to ensure proper function
  • Warranty registration for long-term peace of mind

Our licensed technicians ensure that every replacement meets local codes and manufacturer guidelines.

How to Know It's Time to Upgrade

Tankless water heaters are built to last, but like any appliance, they lose efficiency over time. If you're noticing any of these signs, it may be time to consider a replacement:

  • Inconsistent hot water supply
  • Long wait times before hot water reaches the tap
  • Visible corrosion or mineral buildup
  • Frequent repairs or error codes
  • A unit over 12–15 years old

If your tankless system is showing signs of age or underperformance, Colorado Air Solutions can help assess whether a repair or full replacement makes the most sense.

Choosing the Right Tankless System for Your Denver Home

Tankless water heaters aren't one-size-fits-all. Flow rate, fuel type, number of fixtures, and overall home usage all influence which unit is right for you. We offer:

  • Natural Gas and Propane models
  • High-efficiency condensing units with dual heat exchangers
  • Recirculation systems for faster hot water delivery
  • Units ranging from 6 to 11+ gallons per minute
  • Indoor and outdoor models depending on home configuration

We'll walk you through your options and install the system that best matches your family's needs and budget.

Tankless Water Heater Brands We Trust

As experienced HVAC and plumbing professionals, we only install systems we believe in. Our top tankless water heater brands include:

Navien

Known for its energy efficiency, long warranties, and advanced condensing technology, Navien offers models ideal for both small and large homes.

Rinnai

With decades of innovation and American-based support, Rinnai units offer high flow rates, reliable heating, and Wi-Fi compatibility.

Noritz & Rheem

Popular and dependable, these tankless systems deliver solid performance, long life, and customizable accessories for home installations.

We'll help you compare models and choose the right fit — and we're always transparent about what will work best, not just what's the most expensive.

Frequently Asked Questions About Tankless Water Heaters

A tankless water heater, also known as an on-demand water heater, heats water only when you need it. Instead of storing hot water in a tank, it activates when you turn on a faucet, using gas or electricity to instantly heat cold water as it flows through the unit. This provides continuous hot water without wasting energy.

Yes. With Colorado's fluctuating seasons and growing energy costs, switching to a tankless water heater can save money over time. These systems are more efficient than traditional tank models and can last over 20 years with proper maintenance. Many Denver homeowners appreciate the combination of performance, energy savings, and space efficiency.

Most installations take about one day. If we're replacing an old tank-style unit, extra time may be needed for gas line upgrades, venting, or electrical work. Colorado Air Solutions ensures your installation is completed efficiently and safely, with full code compliance and inspection.

We install top-rated brands like Navien, Rinnai, Rheem, and Noritz. These systems are known for durability, efficiency, and advanced features like recirculation pumps, remote controls, and high GPM (gallons per minute) output. We'll help you choose the best model for your home based on your budget and usage.

Yes, but proper sizing is essential. We'll assess the number of bathrooms, appliances, and your family's daily usage to determine the right unit size and flow rate. For larger homes or simultaneous usage in multiple areas, we may recommend a high-capacity model or dual-unit setup.

Yes. Colorado Air Solutions offers flexible financing options with approved credit, making it easier to upgrade your home's water heating system without straining your budget. We'll walk you through your options and help you apply.

Tankless systems require annual maintenance to stay efficient and reliable. This typically includes flushing to remove mineral buildup, checking filters, inspecting gas lines, and testing components. We offer affordable maintenance plans to keep your system in peak condition year-round.

Yes. Many homeowners switch from tank-style to tankless water heaters. We'll inspect your current plumbing, gas lines, and venting to ensure compatibility, then handle the full conversion. We also take care of permit requirements and safe removal of your old unit.

If you're experiencing inconsistent hot water, rising energy bills, loud noises, rust-colored water, or your system is over 10–12 years old, it may be time to upgrade. We'll inspect your current setup and give honest recommendations on whether a replacement makes sense.

Yes. Although the initial cost is higher, tankless models use less energy and eliminate standby losses from constantly reheating water. Over time, this results in lower utility bills, especially for households with high hot water demand.

They are. Since they only operate when hot water is needed, they reduce energy consumption and carbon output. Many models are ENERGY STAR® certified and contribute to a more sustainable, eco-conscious home.
