Is a Tankless Water Heater Right for Your Home?
A tankless water heater heats water on demand instead of storing it in a tank. That means you’re not paying to keep 40 or 50 gallons hot around the clock. According to the U.S. Department of Energy, tankless water heaters are 24 to 34 percent more energy efficient than conventional tank units for homes that use 41 gallons or less per day. For higher-use households, they still save 8 to 14 percent.
Bailey Bros. has been installing and servicing tankless water heaters across Central Maryland since 2018. Our team is led by a licensed Master Plumber and Master Gas Fitter, which matters because most tankless installations require gas line evaluation, proper venting, and code-compliant connections. We handle the full scope, from initial assessment through installation, and we service all major brands.
We serve homeowners and commercial properties throughout the Greater Baltimore area, the I-95 corridor, and the Chesapeake Bay region. Financing is available through Wisetack for tankless installations and conversions.

Signs It's Time to Consider Tankless
Traditional tank water heaters last 10 to 15 years. A tankless unit can operate efficiently for 20 or more years with proper maintenance. If your current tank is approaching the end of its lifespan, upgrading to tankless can be more cost-effective than replacing it with another tank.
If your household regularly runs out of hot water during back-to-back showers or laundry cycles, a tankless unit solves that problem. It heats water as it flows, so the supply doesn't run dry the way it does with a storage tank.
Water heating accounts for about 18 percent of a home's energy use, according to the Department of Energy. A tank unit that's losing efficiency due to sediment buildup or age drives that number higher. Tankless units only fire when you need hot water, which cuts standby energy loss to zero.
A standard 50-gallon tank takes up roughly 5 square feet of floor space. A wall-mounted tankless unit frees that space entirely. For smaller homes, finished basements, or tight utility rooms, the space savings can matter.
Rusty water from the hot side usually means your tank's interior lining is corroding. Once corrosion starts, a leak is coming. This is a clear signal to replace the unit rather than repair it, and a good time to evaluate whether tankless makes sense.
Sediment buildup on the bottom of a tank hardens over time and causes popping or rumbling noises during heating cycles. It reduces efficiency and shortens the tank's life. If flushing doesn't fix the noise, the tank is nearing the end.
Tankless Services We Provide
Tankless Water Heater Installation
New construction or adding a tankless unit to a home that’s never had one. We size the unit to your household’s demand, evaluate your gas line capacity, and handle all venting and code requirements. Most whole-home tankless units require 150,000 to 199,000 BTU input, which often means upgrading the gas line from a standard 1/2-inch to a 3/4-inch supply.
Tank-to-Tankless Conversion
Switching from a traditional tank to a tankless unit involves more than a simple swap. We remove the old tank, assess your gas line sizing, install proper venting (direct vent or power vent depending on the unit and location), and run the new connections. The result is on-demand hot water and a smaller footprint.
Tankless Water Heater Repair
Error codes, ignition failures, fluctuating water temperature, and mineral scale buildup are the most common tankless issues we see. We service Rinnai, Navien, Noritz, and all other major brands. Same-day repair service is available across our full service area.
Tankless Water Heater Maintenance
Annual flushing removes mineral scale from the heat exchanger and keeps the unit running at peak efficiency. Central Maryland’s municipal water and well water both carry enough mineral content to affect performance over time. Regular maintenance protects your investment and maintains your manufacturer warranty coverage.
Why Homeowners Are Switching to Tankless
Lower Monthly Energy Costs
An Energy Star-certified tankless water heater saves a typical family about $95 per year on gas bills compared to a standard tank model. Over the unit’s 20-plus year lifespan, that adds up to roughly $1,800 in energy savings.
A Unit That Outlasts the Tank
Tankless water heaters last 20 or more years. Most tank units need replacing within 10 to 15 years. Over the life of a home, that means fewer replacements, fewer installations, and less disruption.
Hot Water That Doesn't Run Out
Tank units store a fixed amount of hot water. When it’s gone, you wait for recovery. A tankless unit heats water as it flows through, so back-to-back showers, running the dishwasher while doing laundry, and filling a large tub all work without running cold.
Compact, Wall-Mounted Design
Tankless units mount on a wall and take up a fraction of the space a 40- or 50-gallon tank requires. For finished basements, utility closets, and tight mechanical rooms, the space savings can free up usable square footage.
Financing Makesthe Upgrade Accessible
Tankless installation costs more upfront than a standard tank replacement. We offer financing through Wisetack with monthly payment plans for all credit levels. Combined with our current $400 off tankless upgrade special, the cost becomes manageable. The long-term savings on energy and replacement costs offset the initial investment.
What a Tankless Installation Includes
Every tankless installation from Bailey Bros. covers the full scope. We don’t just hang the unit on the wall and leave. Here’s what’s included:
Assessment and Sizing
We evaluate your household’s hot water demand, the number of fixtures, your incoming water temperature, and your existing gas and venting setup. The right unit size depends on all of these factors. An undersized unit produces lukewarm water during peak demand. An oversized unit wastes money on equipment you don’t need.
Gas Line Evaluation and Upgrade
Tankless units draw significantly more BTUs than a standard tank water heater. If your gas line isn’t sized to handle the increased demand, we upgrade it as part of the installation. Our team includes a Master Gas Fitter, so gas line work stays in-house with one licensed contractor.
Venting and Exhaust
Tankless units require proper venting to the exterior. Depending on the unit type and location, that means direct vent, power vent, or concentric venting. We install the appropriate venting system and ensure it meets Maryland code.
Installation, Testing, and Cleanup
We install the unit, connect all water, gas, and electrical lines, test for leaks and proper operation, verify the temperature output, and clean up the work area. Old tank units are removed and hauled away. We walk you through the unit’s operation and maintenance schedule before we leave.
Hear It From Your Neighbors
Very Professional and gets the job done! Bailey Bros was recommended to me by a friend who is a general contractor. They came and were very transparent with everything that needed to be done. They were professional and courteous as they explained everything before and during the process. They had to dig a very deep trench to access my sewer line and they returned the following days to finish, re-seed and straw my yard. Thank you! I have peace-of-mind knowing the task was done right.
I was having problems with my toilet and was looking for a plumber. I called Bailey Bros. and spoke with Ray on the first call. He came to my home and fixed the issue. He was very professional and easy to deal with from the first conversation I had with him. He was great! I will only call Bailey Brothers for any plumbing issues I have in the future.
Had these guys install a hot water heater for me. I bought the heater and they were gracious enough to install it. They were friendly, responsive and the least expensive after a comprehensive search. Significantly less expensive. They were thorough and explained everything. Shawn (my tech) was charming. Someone you’d be happy to go out and have a drink with. They have a 5 star rating. They ran a little late, but for the savings and quality of work, it was well worth it. The basement was a little cleaner after their work than before they arrived. I highly recommend them.
Thank you Shawn and Mike! My water heater busted on a Saturday and they were able to install a new one within a few days! 🥰 you guys are awesome! It’s so much better than the old one from 1999! 🫠
Tankless Water Heater Questions
How much does a tankless water heater cost?
The unit itself and the installation scope both affect the total. Gas line upgrades, venting, and the brand and model you choose all play a role. We provide upfront pricing before any work begins. Financing is available through Wisetack for monthly payment plans.
Is tankless worth it over a regular water heater?
For most homes, yes. The energy savings, longer lifespan, and endless hot water supply make tankless a strong long-term investment. The upfront cost is higher, but financing and our $400 spring special help close that gap. We’ll walk you through the numbers during your estimate.
What brands do you install?
We install and service Rinnai, Navien, Noritz, and other major tankless brands. We’ll recommend the right unit based on your household’s demand, your gas setup, and your budget.
Does my gas line need to be upgraded?
Often, yes. Most whole-home tankless units require a 3/4-inch gas supply line, while many Maryland homes have a 1/2-inch line running to the existing tank water heater. We evaluate your gas line as part of every tankless estimate and include any upgrades in the quoted price.
How long does tankless installation take?
A straightforward replacement takes 4 to 6 hours. Tank-to-tankless conversions that require gas line upgrades and new venting typically take a full day. We’ll give you a time estimate specific to your job before we start.
How often does a tankless water heater need maintenance?
Annual flushing is recommended to remove mineral scale from the heat exchanger. Central Maryland’s water carries enough mineral content to affect performance if maintenance is skipped. A flush takes about an hour and extends the life of your unit.
Can a tankless water heater supply a whole house?
Yes. A properly sized whole-home tankless unit handles multiple fixtures running at the same time. Sizing depends on the number of fixtures, the flow rate demand, and incoming water temperature. We size every installation to your household’s actual usage.
Do you offer financing for tankless installation?
Yes. We offer financing through Wisetack with easy approval and monthly payment plans for all credit levels. You can combine financing with our current $400 off tankless upgrade special. Call (443) 787-5995 or book online to get started.
