Are you tired of running out of hot water halfway through your morning shower? If you live in Littleton or the surrounding Colorado communities, you know how brutal it is to have the water suddenly turn ice-cold during the winter months. For decades, homeowners relied on massive, bulky traditional water heater tanks that stored and constantly reheated 40 to 50 gallons of water. But today, there is a vastly superior alternative: the tankless water heater.
Also known as "on-demand" water heaters, tankless units are rapidly becoming the standard for modern residential plumbing. At Plumbing Littleton CO, we’ve seen firsthand how upgrading to a high-efficiency tankless system can dramatically improve a family's comfort while simultaneously lowering their monthly utility bills. If you are on the fence about whether to repair your aging tank or invest in a tankless upgrade, this comprehensive guide will walk you through the top benefits.
The single most popular reason homeowners switch to a tankless system is the promise of endless hot water. Traditional tanks hold a finite amount of hot water. Once you use up that 40 or 50 gallons—say, by running the dishwasher and taking a long shower simultaneously—you have to wait 30 to 45 minutes for the tank to refill and reheat.
A tankless water heater operates entirely differently. It utilizes powerful gas burners or electric heating elements to flash-heat water on demand as it passes through the unit. Because it only heats water when you turn the tap on, the supply is effectively limitless. You can run multiple showers, a load of laundry, and the dishwasher at the exact same time without ever experiencing a drop in temperature. For large families, this benefit alone is often worth the investment.
Did you know that your water heater is the second largest energy consumer in your home, right behind your HVAC system? Traditional water heaters suffer from what is known as "standby heat loss." They must run their burners 24 hours a day, 7 days a week, to keep the stored water at 120 degrees, even while you are sleeping or away at work.
Tankless water heaters completely eliminate standby heat loss. They remain completely dormant until you turn on a hot water tap. By only heating water when it is actively needed, a tankless unit can be up to 34% more energy-efficient than a standard storage tank for homes that use less than 41 gallons of hot water daily. Over the lifespan of the unit, this translates to hundreds, if not thousands, of dollars in energy savings.
If you live in an older home in Englewood, Centennial, or Littleton, you know that utility space is at a premium. Traditional water heaters are gigantic metal cylinders that take up a massive footprint in your basement, garage, or utility closet.
Tankless water heaters are incredibly compact. Most units are about the size of a small carry-on suitcase and are mounted securely to the wall. This frees up significant square footage in your home, allowing you to utilize that space for additional storage or even a finished basement remodel.
Water heaters are a significant investment, and you want them to last. Traditional tank water heaters have an average lifespan of 8 to 12 years. Because they constantly hold water, they are highly susceptible to internal corrosion and mineral scale buildup, which eventually causes the tank to rupture and leak.
Tankless water heaters, on the other hand, do not store water, which drastically reduces their exposure to corrosive minerals. With routine maintenance—such as annual flushing to remove scale—a high-quality tankless unit can easily last 20 years or more. Furthermore, unlike traditional tanks that must be entirely replaced when they fail, tankless units have replaceable parts, making them far easier to service and repair.
One common question we hear from homeowners is whether tankless water heaters can keep up with freezing Colorado groundwater temperatures during the winter. The answer is absolutely yes—provided the unit is properly sized.
Because groundwater in Littleton can drop to near-freezing temperatures in January, a tankless heater must work harder to raise the water temperature to a comfortable 120 degrees. This requires a unit with a high BTU (British Thermal Unit) rating. When you hire professional Water Heater Repair & Installation experts like us, we carefully calculate your home’s peak water demand and groundwater temperature to ensure we install a unit robust enough to deliver endless hot water, even in the dead of winter.
When a traditional water heater tank reaches the end of its life, the inner steel lining rusts through. The result is often a catastrophic failure where 50 gallons of water suddenly dumps onto your floor, causing massive water damage to your basement, drywall, and personal belongings.
Because tankless units do not store large volumes of water, the risk of a catastrophic flood is virtually eliminated. If a component fails or a leak develops in a tankless unit, it is typically a minor drip that can be quickly addressed by our Emergency Plumbing team rather than a disastrous deluge.
While the benefits of a tankless water heater are undeniable, proper installation is absolutely critical. Switching from a traditional tank to a tankless unit often requires upgrading your gas line to accommodate the higher BTU demand and installing specialized stainless steel venting to safely exhaust combustion gases. This is not a DIY project.
At Plumbing Littleton CO, our licensed and insured plumbers have extensive experience retrofitting older homes with modern tankless technology. We handle all the necessary permitting, ensure the gas line sizing is safe and code-compliant, and meticulously calibrate the unit for peak performance.
