Frequently Asked Questions
Today, we want to take the opportunity to run through the most common questions we get regarding tankless water heaters.
What’s a Tankless Water Heater?
Let’s start from the top—tankless water heaters are water heaters that create water on demand. You might even hear these systems referred to as “on-demand” water heaters. This is because the water heater starts creating your water heater when you turn on a tap.
Tank water heaters create warm water on a regular basis and then it “stands by” and waits for you to turn on a tap. The main problem with this is that it loses heat while it’s waiting around to be used.
If you have a home that uses around 41 gallons or less of hot water per day, then a tankless water heater is the right move for you. In fact, these types of water heaters can perform 24-34% more efficiently than a standard water heater could. This high efficiency is only possible when the unit’s performance is maintained through regular upkeep. Most manufacturers recommend following specific maintenance schedules to ensure optimal operation, and water hardness can increase the frequency of required maintenance. If you have hard water, you may need to perform maintenance on your tankless water heater more frequently to prevent mineral buildup. Even if you use more hot water than this on a regular basis, a tankless water heater could save you around 8% to 15% more when it comes to your efficiency.
Why Should You Get One?
Are you still wondering why you should get a tankless water heater? Here are a few reasons:
- Efficiency: We mentioned it above, but we can’t reiterate it enough—tankless water heaters are efficient. The elimination of standby heat loss helps save you both energy and money.
- Longer Lifespan: Tankless water heaters are more expensive than tank units, but they make up for it in several ways. One of these ways is that they last much longer.
- Cost Savings: Saving on your energy emissions means that you’re also saving on cost. We all want to save where we can in our home and an investment in one of these systems is an easy way to do it.
- Never Run Out of Hot Water: One of the biggest perks of a tankless water heater is that you never run out of hot water. The days of taking a shower and having it run cold halfway through are gone. You’ll always have the hot water you need with one of these systems.
- Maintenance Matters: Regular tankless water heater maintenance, including flushing the system to remove mineral deposits and sediment buildup, is essential to keep your unit running efficiently and to avoid costly repairs or breakdowns. Annual professional maintenance inspections are recommended to check internal components and ensure peak performance. Neglecting maintenance can lead to high energy bills, lack of hot water, and expensive repairs.

Types of Tankless Hot Water Heater
When it comes to choosing a tankless hot water heater, it’s important to understand the different types available and how they can fit your home’s needs. Unlike traditional tank-type water heaters that store and constantly heat a large volume of water, tankless water heaters heat water only when you need it—right as it flows through the unit. This on-demand approach means you’ll never have to worry about running out of hot water, even during back-to-back showers or busy mornings.
There are three main types of tankless hot water heaters: gas-powered, electric, and hybrid models. Gas-powered tankless water heaters use a powerful gas burner and a heat exchanger to quickly bring your incoming water supply up to temperature. These units are ideal for larger households or homes with high hot water demands, as they can deliver a strong, steady flow of hot water. Gas models also feature air filters that help filter sediments or particles from the air supply, ensuring efficient operation; the air filter should be checked and cleaned or replaced annually to ensure proper combustion and prevent system overheating. Electric tankless water heaters, on the other hand, use electrical resistance to heat the water. They’re often more compact and easier to install, making them a great choice for smaller homes or point-of-use applications. Hybrid models combine the strengths of both gas and electric systems, offering high efficiency and reliable performance. Condensing tankless water heaters utilize flue gases to extract additional heat, which results in the formation of condensate that must be safely managed.
Many leading brands, offer a variety of tankless water heaters with advanced features. Some units come equipped with scale detection software to alert you to mineral buildup, while others use a copper heat exchanger for improved durability and heat transfer. Easy maintenance features, like accessible air intake filters and user-friendly pressure release valves, help keep your tankless water heater running smoothly.
Regular maintenance is key to ensuring your tankless water heater continues to properly heat your water and operates efficiently for years to come. Tasks like descaling the unit to remove mineral buildup, cleaning the air intake filter to ensure proper airflow and efficiency, and checking the pressure release valve should be performed according to the manufacturer’s recommendations. The inlet water filter should be cleaned every 6 to 12 months to prevent debris from clogging the system, and water filters in tankless water heaters should be cleaned regularly to prevent blockages that can damage mechanical components. The process of flushing a tankless water heater typically involves circulating vinegar through the unit using a five gallon bucket and a garden hose, and the hot water valve is used during flushing procedures to facilitate cleaning and vinegar circulation. After flushing, clean water should be used to rinse components, and it is important to let the water run to clear out any remaining sediment or air pockets. If you live in an area with hard water, installing a water softener can help prevent mineral deposits from forming inside the heat exchanger, which can otherwise reduce your unit’s performance and lifespan. Scale build from sediment accumulation can reduce the efficiency of tankless water heaters, so proper maintenance directly impacts the unit’s performance. The venting system should also be inspected periodically, as blockages can cause dangerous carbon monoxide buildup. Always refer to your owner’s manual for specific maintenance requirements, and don’t hesitate to call a professional plumber if you’re unsure about any part of the process.
By selecting the right type of tankless hot water heater and keeping up with regular maintenance, you can enjoy a reliable, energy-efficient supply of hot water while minimizing the risk of costly repairs. Whether you opt for a gas, electric, or hybrid model, today’s tankless systems offer a smart solution for modern homes—delivering hot water exactly when and where you need it, without the bulk and standby energy loss of a storage tank.
Importance of Annual Maintenance for Tankless Water Heaters
Annual maintenance is essential for keeping your tankless water heater running at peak performance and ensuring a long, trouble-free lifespan. Unlike traditional tank-type water heaters, a tankless water heater pushes hot water through a compact heat exchanger, heating it instantly as it flows. Over time, however, mineral buildup—especially in areas with hard water—can accumulate inside the heat exchanger, reducing its ability to properly heat your water and potentially leading to costly repairs or even premature failure.
To prevent these issues, regular maintenance is a must. One of the most important tasks is descaling and flushing the unit, typically using a sump pump and a descaling solution like distilled white vinegar. This process helps remove mineral deposits that can clog the heat exchanger and restrict water flow. Following the manufacturer’s instructions is crucial, as maintenance requirements can vary based on your specific model and local water supply conditions.
In addition to descaling, annual maintenance should include cleaning the air intake filter to ensure proper airflow and prevent overheating. It’s also important to check the pressure release valve and make sure the cold water inlet is free of obstructions. These steps help protect the internal components of your tankless water heater and keep your hot water supply consistent.
If you live in an area with high water hardness, you may need to perform maintenance more frequently—sometimes every six months instead of once a year. Installing a water softener can help reduce mineral buildup and make maintenance easier. Some modern tankless units even feature scale detection software to alert you when it’s time for a flush, helping you stay ahead of potential problems.
While many homeowners are comfortable performing basic maintenance themselves, hiring a professional plumber is always a safe bet—especially if you’re unsure about handling gas lines, pumps, or other internal components. Improper maintenance can void your warranty and lead to expensive damage, so don’t hesitate to call in an expert if needed.
By keeping up with annual maintenance, you’ll not only extend the life of your tankless water heater but also enjoy lower energy bills and a reliable supply of hot water. Regular checkups can catch small issues—like a clogged cold water inlet or a faulty pressure release valve—before they turn into major headaches. Whether you use a water softener, rely on scale detection software, or simply follow your owner’s manual, making maintenance a priority will help your tankless water heater deliver efficient, dependable performance for years to come.
