What Are the Benefits of Tankless Water Heaters?

Tankless hot water heaters are a great alternative to traditional tank water heaters. They provide a continuous stream of hot water, which is perfect for homes with multiple people using hot water at the same time. Tankless water heaters also take up less space than traditional tank water heaters, making them a great option for small homes or apartments. 

Advantages of tankless hot water heaters include:

• Continuous stream of hot water
• Less space required than traditional, bulky tank water heaters
• Energy efficient - save on your energy bill
• Long lifespan - tankless water heaters can last twice as long as traditional water heaters
• Fewer repairs throughout the lifetime of the hot water heater

Tankless Water Heater Installation in Lowell

When installing a tankless water heater, it's important to work with a qualified plumbing professional. At A. Fagundes Plumbing & Heating Inc., we pride ourselves on our workmanship and would be happy to guide you through the process of choosing a system that’s best for your home and family. Our licensed, uniformed plumbers perform installs around your schedule and always leave your space sparkling clean when we’re finished. 

Before we install a new unit, we evaluate your household’s hot water use, gas or electrical capacity, venting options, and the existing plumbing layout so that the system is properly sized for your home. This up-front assessment helps prevent problems like temperature fluctuations or low flow once the system is in place and makes it easier for you to decide whether a single whole-house unit or multiple point-of-use units will work better. Homes in older Lowell neighborhoods may also need updates to gas lines or venting to meet current codes, and our team will explain these requirements clearly before any work begins.

On installation day, we arrive with all needed materials, protect your floors and work areas, and carefully remove your old water heater if you are replacing a tank system. We then mount the new tankless unit, make all gas, water, and power connections, and test the system at different flow rates to confirm that every shower and fixture is getting reliable hot water. Our plumbers walk you through basic operation, maintenance needs, and warranty details before we leave so you feel confident using your new equipment and know exactly who to call if questions come up later.

Tankless Hot Water Heater Repairs 

Tankless water heaters are a great alternative to traditional tank water heaters, but like any other appliance, they may need repairs from time to time. If you're experiencing problems with your tankless water heater, be sure to call A. Fagundes Plumbing & Heating Inc. for speedy repairs. 

Our team of experienced plumbers will help you identify the problem and provide a solution that is right for your needs. We offer repairs for all makes and models of tankless water heaters, and we pride ourselves on providing quality service that is second to none.

Common problems we see with tankless systems include units shutting down mid-shower, inconsistent water temperature, error codes on the display, or reduced hot water flow at fixtures that used to work well. Mineral buildup in the heat exchanger, blocked intake or exhaust vents, and issues with gas supply are frequent causes, especially in New England homes with harder water. When you call us for tankless water heater repair, we arrive with diagnostic tools and replacement parts so we can quickly determine whether cleaning, component replacement, or system adjustments will restore dependable hot water for your household.

During a service visit, we not only address the immediate issue but also check related components such as shut-off valves, isolation valves, and venting connections to look for early signs of wear. This preventive approach helps reduce the chance of repeat breakdowns and gives you a clearer picture of the overall condition of your equipment. If we find that an older unit is nearing the end of its useful life, we will discuss your options, provide straightforward pricing for repair versus replacement, and answer your questions so you can make an informed decision that fits your home and budget.

Tankless Water Heater Maintenance

Tankless water heaters require regular maintenance in order to function properly. Annual maintenance to flush the unit and remove mineral buildup and sediment is important for protecting the longevity of your unit. 

When you invest in regular maintenance service for your tankless water heater, our professionals can catch and correct potential issues early, thus saving you money in the long run. 

During a typical maintenance visit, we shut down and isolate the unit, connect flushing hoses, and run a cleaning solution through the heat exchanger to dissolve scale and sediment. We also clean the inlet screens, check the burner assembly, verify proper combustion, and confirm that safety controls are working as designed. In areas of Massachusetts and New Hampshire with harder water, this service is especially important because scale can form more quickly and reduce the efficiency of your system if it is not removed regularly.

Our plumbers will also review your usage patterns and the manufacturer’s maintenance recommendations so you have a realistic schedule for future service. For many homeowners, pairing annual tankless maintenance with other home comfort checks—such as boiler or furnace tune-ups—provides a convenient way to keep everything running smoothly. If you are enrolled in one of our maintenance plans, we will remind you when service is due and help you plan ahead, which makes it easier to protect your investment and avoid sudden interruptions to your hot water supply.

Don't wait until your tankless water heater stops working completely. Contact A. Fagundes Plumbing & Heating Inc. today at (978) 350-5522 for all of your tankless water heater repair needs!

Is a Tankless Water Heater Right for Me?

While tankless water heaters have many benefits, they also come with a few drawbacks. One of the biggest complaints about tankless water heaters is that they can be more expensive to install than traditional tank water heaters due to the extensive piping involved. 

They also require regular maintenance to ensure proper flushing, which will help avoid corrosion. If you have any questions or concerns about investing in a tankless hot water system, don’t hesitate to contact us for a professional opinion on what would work best for your space. 

When we help you decide whether a tankless system is a good fit, we look at factors such as the number of bathrooms in your home, how many fixtures often run at the same time, and whether you plan to add future features like an additional shower or in-law suite. We also consider your existing gas or electrical service and venting, because upgrades to these components can affect the overall cost of the project. For some homes, especially smaller households or properties with limited mechanical space, the long-term energy savings and space savings of a tankless unit make a lot of sense, while in other situations a high-efficiency tank system may still be the better choice.

Homeowners in communities like Lowell often have a mix of older and newer construction, and each type of home presents different considerations for a new hot water system. We will explain how a tankless unit would be integrated into your particular layout, discuss available rebates for high-efficiency equipment, and review typical operating costs so you can compare options clearly. Our goal is to give you practical information—not pressure—so that you can choose the water heating solution that keeps your household comfortable and aligns with your plans for the property.

Signs You Need Tankless Water Heater Repair

Many homeowners are not sure when a minor nuisance with their hot water crosses the line into a problem that should be checked by a licensed plumber. Paying attention to early warning signs can help you schedule service before you are left without hot water altogether. In our New England climate, losing hot water during a cold snap is more than just an inconvenience, so it pays to know what to watch for and when to call for help.

You might benefit from a repair visit if you notice changes such as water that suddenly runs hot and cold, a new delay before hot water reaches your fixtures, or error codes appearing on the tankless unit’s display. Other red flags include unusual noises from the unit, visible corrosion on connections, or a drop in water pressure when you turn on more than one tap. These symptoms can point to issues like scale buildup, failing sensors, gas supply concerns, or venting problems that require a trained technician to diagnose safely. When you call our team, we walk you through what you are seeing or hearing and help you decide whether a simple adjustment, maintenance visit, or full diagnostic appointment makes the most sense.

Homes in and around Lowell often have older plumbing systems and varying water quality, which can accelerate wear on tankless components if they are not maintained. If your system is more than ten years old or has not been serviced regularly, scheduling a proactive inspection can help you avoid emergency calls and unexpected expenses. During that visit, we will let you know what condition your equipment is in today and outline any steps that can extend its life, so you can plan ahead instead of reacting to a surprise breakdown.

Our Tankless Water Heater Installation Process

Understanding what will happen during an installation can take a lot of stress out of planning a new system. We follow a clear, step-by-step process so you know who will be at your home, how long the work will take, and what your space will look like when everything is finished. That predictability is especially important if you live in a busy household or in a compact Lowell property where every square foot matters.

We begin with an in-home consultation where we review your current water heater, talk through how your family uses hot water each day, and discuss any comfort problems you want to solve, such as running out of hot water during back-to-back showers. From there, we take measurements, check gas or electrical capacity, and evaluate venting routes that comply with local building codes in Massachusetts and New Hampshire. Once we have this information, we present clear options and pricing so you can choose a system that balances up-front cost, efficiency, and performance without surprises.

After you approve the work, we schedule the installation at a time that works with your routine and coordinate any necessary permits or inspections. On the day of the job, our uniformed plumbers protect your home, remove the old equipment if applicable, and install the new tankless unit according to manufacturer standards and local code requirements. We test the system thoroughly, clean up our work area, and review how to operate and care for your new heater before we leave. By the end of the visit, you have a neat, space-saving installation and a clear understanding of how to get the most from your investment.
