Going Tankless: Everything You Want to Know About Tankless Water Heaters
David E.
Have you ever been looking forward to a long, hot shower only to realize a few short minutes in that the hot water was gone? Yeah, we’ve all been there at some point. When our hot water tank runs out of hot water, it can take a while for more to be heated. With tankless water heaters, running out of hot water is a thing of the past. The difference is that it heats the water when you need it and for as long as you need it, so essentially, it won’t run out! They’ve been in the United States since the 1990s, so they’ve been refined and improved for around 30 years and we think they can be a great option. Let’s explore how they work and a few other things you probably want to know about tankless water heaters. As your Birmingham residential plumbing experts, we want to help you make the best plumbing decisions for your home!
How They Work
Tankless water heaters heat water directly without the use of a storage tank. When the hot water knob is turned on (or an appliance on a hot setting), cold water travels through a pipe into the unit, then a heating element or flame heats the water. So essentially, it delivers a constant supply of hot water. You don’t have to wait for a storage tank to fill up again- how nice!
Because they are actively heating the water, tankless water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute, which can be a slower flow rate than you’re used to if you switch (information from Energy.gov). While gas-fired versions produce higher flow rates than electric ones, sometimes even the biggest model cannot supply enough hot water for simultaneous, multiple uses- like taking a shower and running the dishwasher at the same time. No need to worry- one solution is to install two or more tankless water heaters, for those instances of simultaneous demands of hot water. You could also install separate tankless water heaters for appliances (i.e. dishwasher and/or washing machine) that use a lot of hot water in your home.
Tank vs. Tankless: Which is better?
Let’s look at the pros and cons of a tankless hot water heater:
PRO: More energy efficient = lower utility bills
You could save 27 to 50 percent of fuel costs over tank-type heaters. The initial cost is typically higher than that of a conventional storage water heater, but the savings on energy costs adds up and can actually start saving you money.
PRO: Longer lasting
Most tankless water heaters have a life expectancy of more than 20 years whereas storage water heaters last 10–15 years. Additionally, replacement parts for tankless units are easy to install and can further extend the life of the system.
PRO: They’re Compact
Tank-type water heaters take up a lot of room, even if it’s tucked away- think about the extra storage space you could have without it there. Tankless gas heaters are about the size of a suitcase and hang on the wall.
PRO: They’re Safer
Traditional hot water heaters have the potential to spring a leak or even burst. This shouldn’t happen, but we know that things break down over time, so it is a possibility. If a leak happens, flooding happens. No one wants water damage. Because there’s no tank to fail, there’s almost no chance of a catastrophic leak with a tankless system. Also, tankless versions are safer because the air-supply and exhaust vents are sealed, so carbon monoxide can’t leak into the house.
CON: They’re Sensitive to Slow Flow
If there’s too much buildup in the pipes, or a faucet is clogged, the slowed flow can make these units automatically shut off. So they can be more sensitive than their tank-style counterparts.
CON: More expensive and the payback takes a while
Tank heaters can cost an average of $400, whereas tankless models are $1,000 on average. Going tankless may save you about $100 per year, depending on how efficient it is and how much hot water your household uses. So it could take several years for it to start saving you money.
It’s also important to note that it’s recommended to have them professionally cleaned by All City Plumbers about once a year. That’s a good thing because it means your water heater will remain functional for longer and will run efficiently, but it does add something else to your home that needs professional cleaning.
A tankless water heater is a great option for many households looking for energy-efficiency, decreased risk, and “never ending” hot water, but does that mean it’s the right option for your home?

Deciding when to repair or replace your water heater is a vital consideration that impacts home comfort, safety, and energy efficiency. Water heaters are essential household appliances that provide hot water for bathing, cooking, and cleaning, and their performance can significantly influence utility costs and quality of life. Understanding the signs that indicate repair or replacement needs, as well as evaluating the conditions favoring each option, enables homeowners to make informed decisions. This comprehensive article covers these aspects in detail, incorporating valuable information from professionals such as All City Plumbers, insights from tankless water heaters, and the importance of emergency services for critical situations. Recognizing Signs That Repair is Needed Water heaters, like any mechanical system, may experience malfunctions or inefficiencies over time. Early identification of repair needs can extend the life of the unit and prevent costly replacements. Common signs requiring repair include inconsistent water temperature, strange noises such as rumbling or popping caused by sediment buildup, water leaks near the tank or connections, and longer than usual recovery times for heating. Ignoring these symptoms can exacerbate damage, leading to more extensive and expensive repairs. Homeowners should prioritize regular maintenance inspections, ideally conducted by trusted professionals such as All City Plumbers, who can diagnose issues comprehensively and recommend effective repair strategies. In some cases, simple fixes like replacing thermostats or flushing mineral deposits restore functionality efficiently without necessitating full replacement. When Replacement Becomes the Best Option Despite repairs, there comes a time when replacing a water heater is more cost-effective and safer than patching existing problems. Factors influencing the decision to replace include the age of the unit—typically over 10 to 15 years for traditional tanks—repeated and escalating repair costs, inconsistent water quality, and significant leaks that compromise structural integrity. Additionally, adopting new technologies can justify replacement. Tankless water heaters insights reveal their advantages in energy efficiency, longer service life, and space-saving designs compared to conventional models. Upgrading to a tankless system presents opportunities for homeowners looking to reduce energy consumption and enjoy continuous hot water. Professional plumbers, including All City Plumbers, can provide expert evaluations to identify ideal replacement systems tailored to household needs and budgets. Safety Concerns and Emergency Services A malfunctioning water heater can pose safety hazards such as leaks that damage property or, in the case of gas-powered units, risks of carbon monoxide leaks or explosions. Recognizing emergency signs—unusual smells, visible corrosion, or sudden loss of hot water—requires immediate attention. In these instances, accessing emergency services is crucial to prevent injuries or extensive damage. Emergency response teams dispatched by experienced plumbing services expedite diagnosis and mitigate risks, often providing temporary solutions such as shutoff assistance or temporary heating options while permanent repairs or replacements are scheduled. Homeowners are encouraged to establish relationships with reputable providers like All City Plumbers to ensure prioritized emergency support when critical. Maintenance and Longevity Considerations Regular maintenance positively influences whether a water heater can be repaired or requires replacement. Tasks like flushing the tank, inspecting anode rods, and checking for leaks enhance efficiency and delay deterioration. Maintenance regimens tailored to specific systems, including tankless water heaters, further optimize performance and longevity. Professional plumbing companies emphasize preventive care that minimizes unscheduled downtime and maximizes appliance lifespan. Integrating maintenance with proactive monitoring helps identify gradual decline early, allowing timely interventions and cost-effective upkeep. Environmental and Economic Impacts of Repair vs. Replacement Homeowners also weigh environmental and financial factors when deciding between repair and replacement. Newer water heaters, especially tankless models, conform to stringent energy standards reducing carbon footprints and lowering monthly bills. Repairing outdated or inefficient units might temporarily save money but could result in higher operational costs and environmental impacts. Energy rebates, incentives, and financing options offered for upgrades enhance affordability, and professional consultations with experts like All City Plumbers help balance upfront investments with long-term savings. Such holistic considerations ensure that each household’s decision supports sustainability goals alongside comfort and budget priorities. Conclusion Determining when to repair or replace a water heater involves evaluating performance issues, safety concerns, age, and economic factors, supported by expert advice from seasoned plumbers and modern technological insights. Proactive maintenance can defer replacement, but timely transitions to advanced systems, including tankless water heaters, often bring superior efficiency and reliability. Equally, preparedness for emergencies through access to prompt services mitigates risks. Trustworthy services like All City Plumbers provide comprehensive, tailored solutions ensuring homeowners enjoy safe, consistent hot water with optimal investment returns.
