Enjoy reliable, energy-efficient hot water with help from Horizon Services. We provide tankless water heater services in the Denver metro area, with proper sizing and code-compliant installation, accurate and fast repairs, and ongoing maintenance to help you get the best value from your system.

Hot Water On Demand With a Tankless Water Heater

On-demand or tankless water heaters work similarly to traditional units, but without a storage tank. They heat water instantly and only when needed, such as when you turn on a hot water tap. A flow sensor activates the burner or electric element, the heat exchanger quickly brings cold water to a set-point temperature, and the water flows to the appropriate tap or appliance.

Benefits of Tankless Water Heaters

Tankless water heaters offer different benefits, including:

Endless hot water supply: Units warm water rapidly when you turn on a faucet, and you won’t run out of hot water even with long periods of high demand.
Energy savings: Tankless work on demand instead of constantly maintaining an entire tank to account for standby heat loss, and families can save up to $1,800 on gas bills over the unit’s lifetime.
Space-saving design: Tankless water heaters are compact and can be installed on walls in utility rooms or inside closets and cabinets, freeing up valuable floor space.
Longer lifespan: Well-maintained tankless units last about 20 years, exceeding the average lifespan of a tank system by several years and delaying the need for a replacement.

Tankless Water Heater Installation

Horizon Services provides tankless water heater installation in the Denver area. We assess your home’s peak gallon-per-minute hot water demand to determine the correct flow rate, accounting for Denver’s local climate factors, including cold groundwater, combustion efficiency at high altitudes, and scale-causing minerals in your water supply. On installation day, we connect and configure your new unit according to local codes and best practices.

Our tankless water heater installers are experienced with major manufacturers and system types. We install units such as:

Gas tankless water heaters.
Electric tankless water heaters.
Heat pump tankless water heaters.
Condensing tankless water heaters.

Tankless Water Heater Repair

When you notice inconsistent temperatures, strange noises, low hot water pressure, or other signs of a failing unit, rely on Horizon Services for tankless water heater repair near you in Denver. Our licensed technicians accurately diagnose, troubleshoot, and fix tankless water heater systems to restore performance and safety. We’re available 24/7 for urgent residential needs and concerns, so you can prevent further damage and get your water heater back to its normal operation with minimal delay.

Common Tankless Water Heater Problems

Horizon Services handles these common residential tankless hot water heater problems and more:

Heat exchanger scale buildup reducing thermal transfer and energy efficiency.
Exceeded flow rate due to an undersized unit.
Clogged inlet water filters causing low water pressure.
Cold or lukewarm water resulting from ignition or burner failure.
Water leaks from fittings or units.

Tankless Water Heater Maintenance

Tankless water heaters require annual maintenance, depending on water hardness, warranty conditions, usage, and system age. At Horizon Services, we provide tankless water heater maintenance to keep your system operating at peak performance. Professional maintenance with Horizon Services includes:

Descaling the heat exchanger.
Cleaning the inlet and filter.
Testing combustion, gas, and exhaust components.
Checking the condensate neutralizer (for condensing units).
Testing the pressure relief valve.

Regular on-demand water heater maintenance helps your system run safely, efficiently, and for as long as possible. For example, minerals in your water coat, harden, and insulate heating components, and descaling the heat exchanger removes this buildup to restore efficiency and protect your system from excessive wear. Most manufacturers also require proof of professional annual maintenance to preserve the warranty, ensuring that you’re protected in case of a defective part.

Tankless Water Heater Replacement

If your system is approaching the end of its lifespan, choose Horizon Services for tankless water heater replacement in Denver. While repairs can address isolated problems in systems that are otherwise in good condition, replacement is often a better choice for aging units with widespread wear. Call Horizon Services for replacement services if your system is older than 20 years, or if you notice these signs:

Frequently breakdowns or costly repairs.
Visible rust or discolored water.
Leaks or puddles around the unit.
Recurring error codes.
Inconsistent or cold temperatures from hot taps.

Tankless vs. Traditional Water Heaters

Both tankless and traditional water heaters carry certain advantages, depending on your home’s needs. See the differences between tankless versus traditional water heaters:

Capacity: Traditional water heater capacity is based on the tank size, and replenishment may take several hours after heavy demand. Tankless water heaters provide endless hot water, but pressure or temperatures may drop if demand exceeds the flow rate capacity.
Energy efficiency: Traditional units are usually less efficient due to standby heat loss, while efficiency is higher for on-demand systems.
Lifespan: With proper maintenance, tank units last eight to 12 years, while tankless units last 15 to 20 years.
Upfront cost: Compared to tankless units, purchase and installation costs are lower for tank water heaters.
Size: Traditional water heaters require more space to account for the tank and clearance needs. Wall-mounted tankless units are compact and save floor space.

Is a Tankless Water Heater Right for Your Home?

Consider these factors to decide if a tankless water heater is right for your home:

Household demand: Tankless units are well-suited to homes with long periods of hot water demand. Some homes may need higher flow rates or additional units to accommodate larger plumbing systems or multiple fixtures at once.
Budget: Installing a tankless unit has higher upfront costs, but energy savings and longer equipment lifespan improve long-term value.
Space: Compact tankless units take up minimal space in apartments and townhomes.
Fuel source: Existing infrastructure may need upgrades for high-capacity gas lines or electrical circuits.
