Frequently Asked Questions
Tankless water heaters can last up to 20 years or more with proper maintenance. Because they do not store hot water in a tank, they often have a longer lifespan than traditional tank water heaters. Regular flushing, descaling, and inspection are especially important because mineral buildup can affect the heat exchanger, reduce efficiency, and shorten the life of the system.
Tankless water heaters can help reduce energy use because they only heat water when you need it. Unlike traditional tank systems that keep a large amount of water hot throughout the day, tankless units activate on demand. This can improve energy efficiency and may lower monthly utility costs, depending on your household’s water usage, current system, and the model installed.
The right size depends on your home’s hot water demand, number of bathrooms, number of fixtures, appliance usage, fuel type, and how many people may need hot water at the same time. A tankless water heater that is too small may struggle during peak use, while an oversized system may cost more than necessary. Our technicians can evaluate your home and recommend a properly sized unit.
Regular maintenance is important for keeping a tankless water heater working efficiently. A professional descale or flush typically takes 1–2 hours and helps prevent expensive repairs by reducing mineral buildup, especially around the heat exchanger. Routine inspections can also help identify small problems before they affect performance. Cold is on the Right provides tankless water heater maintenance to help extend system lifespan and protect your investment.
Tankless systems can work well for larger households when the unit is properly sized and installed. Homes with high hot water demands may benefit from a larger unit, multiple tankless systems, or a hot water recirculation system, and proper sizing helps maintain consistent hot water for larger households. Our team can review your household’s usage and recommend a setup that supports steady, reliable hot water.
A tankless water heater is a type of hot water heater that heats water on demand instead of storing hot water in a tank. When you turn on a hot water tap, cold water passes through the unit and is heated by gas or electricity as it moves through the system. This design can provide efficient hot water without the standby energy loss associated with traditional tank systems.
Tankless water heaters offer several benefits, including energy efficiency, space-saving design, longer lifespan, and hot water on demand. They can be a smart choice for homeowners who want a modern water heating system that does not rely on a large storage tank. With the right unit and installation, a tankless system can improve comfort and long-term performance.
Tankless water heaters are better for some homes, while traditional tank water heaters may still make sense for others. Tankless systems are efficient, compact, and long-lasting, but they usually have a higher upfront cost and need proper sizing. Traditional tanks are often less expensive to install but may use more energy over time. Our team can help you compare both options based on your home, budget, and hot water needs.
The cost of tankless water heater installation depends on the unit selected, fuel type, home layout, existing plumbing, plumbing system, venting needs, electrical requirements, and whether any upgrades are needed. After reviewing your home and hot water demand, Cold is on the Right can provide upfront pricing and explain what is included before installation begins.
Many homeowners can upgrade from a traditional tank water heater to a tankless system. However, the installation may require plumbing changes, venting updates, electrical work, gas line adjustments, or other modifications, depending on your home. Our plumbers can inspect your current setup and explain what is needed for a safe, reliable conversion.
Gas and electric tankless water heaters both heat water on demand, but they use different energy sources and may have different installation requirements. Gas systems often require proper venting and gas line capacity, while electric systems may require sufficient electrical service. Our team can help determine which option is the best fit for your home.
Even though tankless systems heat water on demand, hot water still has to travel from the unit to the faucet or shower. The farther the fixture is from the water heater, the longer it may take. A hot water recirculation system can help reduce wait times and improve convenience in some homes.
A hot water recirculation system helps move hot water through your plumbing so it reaches fixtures faster. This can be useful in larger homes, homes with long pipe runs, or households that want quicker access to hot water. When paired with the right tankless water heater, it can improve comfort and reduce water waste from waiting at the tap.
A properly sized tankless water heater can provide a steady supply of hot water, but it can still be overwhelmed if too many fixtures or appliances are used at once. For example, multiple showers, laundry, and a dishwasher running at the same time may exceed the system’s flow rate. Proper sizing is key to avoiding performance issues.
Flow rate refers to how much hot water the system can produce at one time, usually measured in gallons per minute. Your home’s required flow rate depends on how many fixtures may use hot water at the same time. Choosing the right flow rate helps make sure your tankless water heater can keep up with your household’s demand.
Inconsistent hot water can be caused by mineral buildup, sediment buildup, a dirty filter, flow rate issues, gas supply problems, error codes, improper sizing, or a failing component. Our technicians can inspect the unit, identify the cause, and recommend the right repair or maintenance service.
Common tankless water heater problems include fluctuating temperatures, error codes, ignition failure, mineral buildup, poor water flow, delayed hot water, system shutdowns, reduced efficiency, and premature failure when buildup or ongoing performance issues are left unresolved. Many of these issues can be corrected with maintenance or repair, especially when they are addressed early.
Cold is on the Right provides tankless water heater repair for Austin homeowners experiencing no hot water, inconsistent temperatures, error codes, low flow, ignition problems, or unusual system behavior. Our technicians diagnose the issue and explain your repair options before work begins.
Cold is on the Right installs tankless water heaters for Austin-area homes and businesses. We help you choose the right model, prepare the installation area, complete the plumbing connections, and make sure the system is set up for safe and efficient operation.
Most tankless water heaters should be flushed once a year, but homes with hard water or heavy hot water usage may need more frequent maintenance. In Austin, an annual flush service is especially important because hard water can reduce efficiency and lead to costly repairs. Our team can recommend the right maintenance schedule for your home to help maintain consistent performance.
Hard water can create mineral scale inside a tankless water heater, especially around the heat exchanger. This buildup can reduce efficiency, cause temperature issues, trigger error codes, and shorten the life of the unit. Regular maintenance and water treatment options can help protect the system.
A water softener can be a smart addition in homes with hard water. By reducing mineral buildup, a softener may help protect the tankless water heater, improve performance, and reduce maintenance issues over time. Our team can evaluate your water quality and recommend whether a softener or filtration system makes sense.
Many tankless water heater installations can be completed in a day, but the timeline depends on your current setup, fuel type, venting requirements, gas or electrical capacity, and whether plumbing modifications are needed. Before installation begins, our team will explain what to expect and provide a clear timeline.
Tankless water heaters can be installed indoors or outdoors depending on the model, manufacturer requirements, home layout, and local code considerations. Outdoor units must be rated for exterior installation, while indoor units need proper venting and placement. Our plumbers can recommend the safest and most practical location.
Tankless water heaters can be a good fit for small homes because they take up less space than traditional tank systems. Their compact design makes them useful for tight utility areas, closets, garages, or homes where space is limited. Proper sizing still matters, even in smaller households.
Tankless water heaters can work well for certain commercial properties, especially when the system is designed around the building’s hot water demand. Restaurants, offices, salons, retail spaces, and other businesses may benefit from efficient on-demand hot water. Our team can evaluate the property and recommend the right setup.
Some tankless water heaters may qualify for manufacturer rebates, utility incentives, or efficiency-related programs, depending on the model and current offerings. Availability can change, so our team can help you review your options during the consultation or point you toward current program details.
