Capital Region Tankless Water Heater Specialists
The Radiant Store provides professional tankless water heater installation, repair, replacement, and maintenance for homeowners and businesses throughout the Greater Capital Region of New York, including Albany, Troy, Schenectady, Clifton Park, Saratoga Springs, and surrounding communities. In this area, tankless water heaters have gained popularity due to their energy efficiency and space-saving design, making them ideal for both residential and commercial properties. Many local businesses and homeowners are switching to these systems to reduce utility costs and enjoy continuous hot water. Tankless water heaters heat water only when needed, eliminating the standby energy losses associated with traditional storage tanks. Additionally, their compact size allows for flexible installation options, making them ideal for homes with limited space.
As a locally owned HVAC company specializing in high-efficiency hydronic and domestic hot water systems, we design and service tankless water heater systems that deliver consistent hot water, improved energy efficiency, and long-term reliability, even during Upstate New York’s coldest months. Unlike traditional tank water heaters, tankless models heat water on demand, eliminating the standby heat loss associated with storage tanks. Additionally, their compact design allows for flexible installation options, making them ideal for both new constructions and retrofits.
What Is a Tankless Water Heater? (On-Demand Hot Water Explained)
A tankless water heater heats water only when it is needed, rather than storing heated water in a tank. When a hot water tap is opened, cold water passes through a high-efficiency heat exchanger and is heated instantly before reaching the fixture. This on-demand heating process eliminates the need for a storage tank, reducing energy consumption and providing a continuous supply of hot water. Additionally, tankless water heaters take up less space and have a longer lifespan compared to traditional tank models, making them an increasingly popular choice for modern homes. Additionally, their energy-efficient design helps reduce utility bills while providing an endless supply of hot water on demand.
How Tankless Systems Differ from Traditional Water Heaters
No storage tank
No standby heat loss
Continuous hot water production
Higher operating efficiency
Longer service life
Tankless water heaters are commonly used in single-family homes, multi-bathroom residences, apartments, restaurants, and commercial buildings where hot water demand is frequent or unpredictable. These heaters provide hot water on demand by heating the water directly as it flows through the unit, eliminating the need for a storage tank. This not only saves space but also reduces energy consumption, making them an efficient and eco-friendly choice for various applications.
Tankless Water Heater Services We Offer
Tankless Water Heater Installation
Installing a tankless water heater is a technical HVAC and plumbing process, not a plug-and-play replacement. Proper installation directly affects performance, safety, efficiency, and warranty coverage. Tankless water heaters require careful calibration of gas, water, and electrical connections to ensure optimal operation. Additionally, professional installation helps prevent issues such as fluctuating water temperatures and potential damage to the unit.
Every installation is designed to meet New York State plumbing and mechanical codes and optimized for Capital Region water temperature and usage patterns.
Tankless Water Heater Replacement
Replacing an existing tankless water heater, or converting from a tank system, requires a detailed evaluation of your current setup. It's important to assess the gas or electrical capacity to ensure it meets the demands of the new unit. Additionally, proper venting and water line sizing must be verified to maximize efficiency and safety.
We remove old equipment, update connections as needed and install modern high-efficiency systems designed for long-term performance.
Tankless Water Heater Repair
Tankless water heaters are reliable, but when problems arise, professional diagnosis is critical. Regular maintenance and timely repairs can significantly extend the lifespan and efficiency of these units. Additionally, addressing issues promptly helps prevent costly damage and ensures continuous hot water supply for your home.
We service most major tankless water heater brands and models commonly installed throughout the Capital Region.
Tankless Water Heater Maintenance & Descaling
Annual maintenance is essential for tankless water heater performance—especially in areas with mineral-rich water, which is common throughout Upstate New York.
Tankless Water Heater Lifespan & Performance Expectations
Average Lifespan
Tank water heaters: 8–12 years
Tankless water heaters: 15–20+ years with proper maintenance
Tankless systems last longer because they are not subject to tank corrosion or continuous reheating cycles.
Gas vs Electric Tankless Water Heaters
Choosing the right system depends on your home’s infrastructure, hot water demand, and efficiency goals. Electric tankless water heaters offer the advantage of compact size and energy savings by heating water only when needed, eliminating standby heat loss associated with traditional storage tanks. Additionally, they are easier to install in homes without existing gas lines, making them a versatile and option for a wide range of households. Their compact size also frees up valuable space, providing homeowners with more room for storage or other uses.

Frequently Asked Questions About Tankless Water Heaters
How long does installation take?
Most installations are completed within one day, depending on system complexity and required upgrades.
Can a tankless water heater replace my existing tank system?
Yes. Many homeowners upgrade from tank systems to tankless with proper evaluation and installation. Tankless water heaters offer continuous hot water while saving space and energy, making them an attractive alternative. However, it’s important to assess your household’s hot water demand and consult a professional to ensure the system meets your needs effectively.
Do tankless water heaters work during power outages?
Electric units require power. Gas units may still need electricity for controls unless equipped with backup power. During a power outage, electric tankless water heaters will not function, making them less reliable in areas prone to blackouts. However, some gas models with battery backup or manual ignition can continue operating, ensuring a continuous supply of hot water even during electrical outages. This feature makes them especially valuable in areas prone to power interruptions, providing reliable comfort and convenience without interruption.
How often should a tankless system be serviced?
Annual maintenance is recommended. Regular servicing helps ensure optimal performance and extends the lifespan of the unit. During maintenance, technicians typically clean the system, check for mineral buildup, and inspect all components for wear or damage.
