Why Indianapolis Homeowners Are Making the Switch to On-Demand Hot Water
Tankless water heater installation Indianapolis IN offers homeowners a modern solution to one of the most common frustrations: running out of hot water at the worst possible moment. Whether you’re dealing with a traditional tank that can’t keep up with your family’s demand, rising energy bills from heating water 24/7, or simply looking to reclaim valuable space in your basement, a tankless system provides continuous hot water while saving energy and lasting twice as long as conventional units.
Key Benefits of Professional Installation:
1. Energy Savings – Reduce energy use by 24-34% compared to traditional tank heaters
2. Endless Hot Water – Heat water on demand, never run out during back-to-back showers
3. Longer Lifespan – Last up to 20 years with proper maintenance vs. 10-12 years for tanks
4. Space Savings – Compact wall-mounted units (28″ x 20″ x 10″) free up floor space
5. Professional Assessment – Proper sizing based on your home’s peak demand and flow rate (GPM)
6. Expert Installation – Gas line connections, venting, electrical work, and permit compliance
The installation process involves evaluating your existing plumbing and gas or electrical systems, properly sizing the unit based on your household’s hot water usage (typically 4-8 GPM), and ensuring all connections meet local Indianapolis building codes. Professional installation is essential—tankless units require specific venting for gas models, adequate electrical capacity for electric models, and precise water line connections to deliver optimal performance.
I’m Jeff Rich II, and I’ve spent years helping Indianapolis homeowners steer the transition from traditional tank systems to efficient tankless technology through countless tankless water heater installation Indianapolis IN projects. My experience has shown me that proper sizing and professional installation are the two most critical factors in ensuring homeowners get the energy savings and endless hot water they expect from their investment.
Why Indianapolis Homeowners Are Switching to Tankless Water Heaters
Imagine never again having to rush a shower because someone else needs hot water, or wincing at the thought of your energy bill constantly heating a tank of water you might not even use for hours. This dream is becoming a reality for many homeowners in Indianapolis and surrounding areas like Carmel, Fishers, and Greenwood, thanks to the benefits of tankless water heaters.
Energy Efficiency
One of the most compelling reasons to consider a tankless water heater installation Indianapolis IN is the significant boost in energy efficiency. Traditional tank water heaters continuously heat a large volume of water, even when you don’t need it. This constant heating leads to “standby heat loss,” essentially wasting energy as the water sits there, waiting to be used.
Tankless water heaters, on the other hand, operate on an “on-demand” basis. They only heat water when a hot water tap is turned on, eliminating standby heat loss. This difference can lead to substantial savings. Our research indicates that tankless water heaters can reduce energy usage by up to 24 to 34 percent compared to typical tank heaters. For an average Indianapolis household, this could translate to saving hundreds of dollars each year, conserving almost 27 to 50 percent more energy than traditional tank heaters. Considering that heating water accounts for about 14% of a home’s utility bill, these savings are certainly something to smile about! Tankless models are up to 34% more efficient than tank units, potentially saving homeowners up to 40% on their energy bills.
Endless Hot Water
Perhaps the most beloved feature of tankless water heaters is the promise of an endless hot water supply. With a traditional tank, once you’ve used up the stored hot water, you have to wait for the tank to refill and reheat, which can take 30-40 minutes or more. This is why you often find yourself taking a cold shower if you’re the last one in the family.
A tankless system eliminates this problem entirely. When you turn on a hot water tap, cold water travels through a pipe into the unit, where a powerful gas burner or electric heating element quickly heats it. This means you get hot water when you need it, for as long as you need it, ensuring everyone in the family can enjoy a comfortable shower without fighting over the hot water. No more dreading that cold blast!
Longer Lifespan
When we invest in home appliances, we want them to last. Tankless water heaters shine in this department too. While a traditional tank water heater typically lasts about 10 to 15 years (often with an 8-10 year warranty), a tankless unit boasts a significantly longer lifespan, often around 20 years. Many tankless units even come with a 10 to 15-year warranty, reflecting manufacturers’ confidence in their durability. This extended lifespan means fewer replacements over time, offering greater peace of mind and long-term value.
Space-Saving Design
Traditional water heater tanks are bulky, often standing around 60 inches tall and 24 inches wide, taking up valuable floor space in basements, utility closets, or garages. Tankless water heaters are much more compact, typically measuring around 28 inches tall, 20 inches wide, and 10 inches deep. Their small size allows them to be mounted on a wall, freeing up precious floor space for storage, a workbench, or even a small home gym. This space-saving benefit is particularly appreciated in smaller homes or those with limited utility areas in communities like Westfield or Zionsville.

Choosing the Right Tankless Unit for Your Home
Selecting the perfect tankless water heater for your home isn’t just about picking the first one you see. It requires a thoughtful assessment of your household’s unique needs, plumbing system, and energy preferences. That’s where our professional assessment comes in. We carefully evaluate your home to ensure the unit we recommend provides optimal performance and efficiency.
For a broader understanding of water heater options, check out our guide on More info about water heater installation indianapolis in.
Gas vs. Electric Tankless Water Heaters
The first major decision when considering tankless water heater installation Indianapolis IN is choosing between a gas (natural gas or propane) and an electric model. Both have their advantages:
- Gas Tankless Water Heaters: These units typically use natural gas or propane to heat water. They are known for their high output and ability to handle larger hot water demands, making them a popular choice for many homes. However, gas units require proper venting to expel combustion gases safely to the outdoors. If you’re converting from an electric tank to a gas tankless unit, you might need to install or upgrade your gas line and venting system, which can impact the initial installation.
- Electric Tankless Water Heaters: Electric models are often easier to install in homes that don’t have natural gas lines, as they don’t require venting. They can be very energy-efficient, with some models being up to 55% more efficient than electric tank hot water heaters. However, they typically require a significant amount of electricity, which might necessitate an upgrade to your home’s electrical panel or wiring to ensure it can handle the load.
The best choice for your home in areas like McCordsville or Pendleton depends on factors such as the availability and cost of natural gas and electricity in your area, your home’s existing infrastructure, and your preferences for efficiency and environmental impact. We’ll help you weigh these factors to make an informed decision.
How to Size Your Tankless Water Heater
Properly sizing your tankless water heater is critical to ensuring you never run out of hot water, even during peak demand. This involves two main considerations: Flow Rate (GPM) and Temperature Rise.
- Flow Rate (GPM): This measures how many gallons of hot water per minute the unit can produce. To determine your needed GPM, we consider your household’s peak hot water demand – meaning how many hot water fixtures you anticipate using simultaneously. For example, if you often have two showers running while the dishwasher is on, we’ll calculate the combined GPM needed.
- Temperature Rise: This is the difference between the incoming cold water temperature and your desired hot water output temperature (we generally recommend 120 degrees Fahrenheit for safety and efficiency). In colder climates like Indianapolis, especially during winter, the incoming groundwater temperature can be quite low. A tankless unit’s GPM output decreases as the required temperature rise increases. We factor in these local conditions to ensure your unit performs optimally year-round.
Here’s a look at typical flow rates for common household fixtures:
- Faucets: 0.75 Gallons to 2.5 Gallons per Minute
- Low-Flow Shower Heads: 1.2 Gallons to 2 Gallons per Minute
- Older Standard Shower Heads: 2.5 Gallons to 3.5 Gallons per Minute
- Clothes Washers and Dishwashers: 1 Gallon to 2 Gallons per Minute
By adding up the GPM of the fixtures you might use at once, we can determine the appropriate size for your tankless water heater. For larger households or homes with very high hot water demands, sometimes two tankless systems or a larger model might be necessary, especially if your household uses more than 85 gallons of hot water a day. Our expert plumbers will conduct a thorough assessment to recommend the perfect size for your home in Fortville, New Palestine, or anywhere in our service area.

Pre-Installation Assessment
Before any tools are even picked up, our team conducts a comprehensive pre-installation assessment. This crucial step involves:
- Evaluating Existing Plumbing: We check your current water lines to ensure they are compatible with the new tankless system and can handle the required flow. Sometimes, minor adjustments or upgrades to existing pipes are needed.
- Gas Line Capacity (for gas units): If you’re opting for a gas tankless water heater, we’ll assess your current gas line to confirm it can supply the necessary BTUs for the unit. Tankless gas heaters often require a larger gas line than traditional tank models, and an upgrade might be necessary for safe and efficient operation.
- Electrical System Check (for electric units): For electric tankless models, we verify that your home’s electrical panel has sufficient capacity and that the wiring is appropriate for the unit’s power demands. Proper wire sizing is essential for safety and to prevent overloading your electrical system.
- Choosing an Installation Location: Tankless units are compact, offering flexibility in placement. We’ll identify the best spot, considering factors like access to adequate combustion air (for gas models), proximity to a suitable exhaust vent, and protection from cold temperatures (we generally don’t install tankless units outdoors in colder climates like ours).
Our team of expert More info about indianapolis plumbers ensures every detail is covered.
The Installation Process

Long-Term Care: Maintenance and Replacement Signs
Just like any other major appliance in your home, your tankless water heater needs a little love to keep it running smoothly. Regular maintenance is the secret to ensuring system longevity and peak performance for your tankless water heater installation Indianapolis IN.
For more detailed information on tankless systems, you can always revisit our main guide on More info about tankless water heater installation indianapolis in.
Essential Maintenance for Longevity
While tankless water heaters require less maintenance than traditional tank units, they still need some attention to prevent issues and extend their lifespan.
- Annual Descaling: This is perhaps the most crucial maintenance task, especially in areas with hard water like Indianapolis. Hard water contains minerals that can build up inside the heat exchanger, restricting water flow and reducing efficiency. This mineral buildup can also cause damage to the heat exchanger over time. Descaling involves flushing the system with a vinegar solution to dissolve these mineral deposits.
- Flushing the System: Beyond descaling, a full system flush helps remove any sediment or debris that may have accumulated, ensuring clear pathways for water.
- Cleaning Filters: Some tankless units have air intake filters that need to be cleaned periodically to ensure proper airflow for combustion.
- Professional Servicing: We recommend professional servicing at least once a year. If your water heater is set to a high temperature or you have particularly hard water, every six months might be beneficial. Many tankless water heater manufacturers even require professional maintenance for the warranty to remain valid, so it’s a smart move on multiple fronts.

Signs Your Water Heater Needs Attention
Even with diligent maintenance, all appliances eventually reach the end of their useful life. Knowing the signs that your water heater, whether tankless or traditional, needs attention can save you from bigger headaches down the road.
- Age: While tankless units can last up to 20 years, and traditional tanks typically last 10-15 years, an aging unit is more prone to problems. If your tankless unit is approaching the 15-20 year mark, it’s wise to start thinking about replacement options.
- Reduced Water Pressure: A sudden or gradual decrease in hot water pressure can indicate mineral buildup within the unit or pipes, or a failing component.
- Inconsistent Temperatures: If your hot water is lukewarm, fluctuates wildly, or runs out much faster than usual, your unit might be struggling to heat water efficiently or experiencing control issues.
- Strange Noises: Popping, hissing, clanking, or rumbling sounds coming from your water heater can signal mineral buildup or internal component issues.
- Leaks or Water Damage: Although tankless units don’t have a large tank to rupture, leaks can still occur from connections or internal components. Any sign of water around the unit should be addressed promptly.
- Rising Utility Bills: An unexpected spike in your energy bill, without a change in usage, could mean your water heater is losing efficiency and working harder to heat water.
Don’t wait until a small issue becomes a major problem. If you notice any of these signs, it’s time to call in the professionals. Learn more about identifying problems with your water heater in our guide on More info about signs your water heater needs repair in indianapolis in.
Frequently Asked Questions about Tankless Water Heaters
We often get a lot of great questions from homeowners in Indianapolis about tankless water heaters. Here are some of the most common ones we hear:
How long do tankless water heaters last?
With proper maintenance, a tankless water heater can last significantly longer than a traditional tank model. Our research shows that tankless units typically last around 20 years, which is roughly twice the lifespan of conventional tank water heaters that usually last between 10 to 12 years. Regular annual servicing, especially descaling, is key to achieving this impressive longevity.
Can a tankless water heater handle a large family’s needs?
Absolutely! When properly sized and professionally installed, a tankless water heater can easily meet the demands of a large family. The key is that “proper sizing” we discussed earlier, which involves calculating your home’s peak hot water demand (GPM). Because they heat water on demand, tankless units provide a continuous supply of hot water. For very large households that might use over 85 gallons of hot water daily or have multiple simultaneous hot water demands, we might even recommend installing two tankless systems or a larger, high-capacity model to ensure everyone gets all the hot water they need.
Do tankless water heaters work during a power outage?
This is a common and important question. Unfortunately, tankless water heaters, whether gas or electric, do require electricity to operate. This is because they use electricity for their ignition, control systems, and often for their fan to vent exhaust. So, during a power outage, your tankless water heater will not be able to produce hot water. If you live in an area prone to outages and depend on continuous hot water, you might consider installing a battery backup system or a generator to keep your tankless unit running when the power goes out.
