Tankless water heater installation
in Little Rock, AR
Your current water heater is a huge tank sitting in your garage or utility closet taking up valuable space. It runs out of hot water when multiple people shower, and your energy bills stay high because it keeps water hot 24/7 even when nobody's using it. You've heard about tankless water heaters that heat water on demand, never run out, and cost less to operate.
We're a local plumbing company that installs tankless water heaters throughout Little Rock. From older homes in Hillcrest, Heights, downtown to new construction in Pleasant Valley, we help homeowners switch to tankless systems that save space, energy, and money.
Your Local Plumber: On-Demand Hot Water
Tankless water heater installation means putting in a system that heats water instantly as it flows through the unit instead of storing hot water in a tank. The tankless unit mounts on your wall and takes up about as much space as a suitcase. When you turn on hot water anywhere in your home, cold water flows through the unit, gets heated by electric elements or a gas burner, and comes out hot at your faucet.
Traditional tank water heaters common in neighborhoods like The Heights and Riverdale heat 40 to 50 gallons of water and keep it hot all day. This wastes energy because the water sits there losing heat even when you're at work or asleep. Tankless systems only heat water when you actually need it, which can cut your water heating costs by 25 to 40 percent.
Tankless units also never run out of hot water. With a tank system, once you use up the 40 or 50 gallons, you wait 30 to 60 minutes for more hot water. With tankless, you can shower for an hour straight or run multiple showers at once and the hot water keeps coming. This makes them popular in larger homes throughout West Little Rock and Chenal Valley where families need lots of hot water at the same time. Depending on the size of your home, we can properly size the tankless model to be the perfect fit.
The installation process is more complicated than replacing a regular water heater because tankless units need different connections. Electric tankless heaters require upgraded electrical service. They pull a lot of power all at once when heating water. Gas tankless units need larger gas lines and special venting that regular tank heaters don't require. Older homes in the Quapaw Quarter and Governor's Mansion District often need electrical panel upgrades or gas line work before we can install tankless systems. Depending on your current water heater setup and the size of tankless system you need, you may need to upgrade your existing infrastructure to support the new unit. This ensures you get a fully optimized system that delivers unlimited water. No more running out during that relaxing bath after a long day.
Signs You Need Tankless Water Heater Installation
Installing a tankless water heater gives you endless hot water. You never have to time your showers around other family members or wait for the tank to refill. Everyone can shower back-to-back without running cold, and you can fill a large bathtub without worrying about using up all the hot water.
You save space in your home. The tankless unit mounts on a wall in your garage, utility room, basement, or even outside. This frees up the floor space your old tank water heater occupied. Some people add storage shelves in that spot, others just appreciate the cleaner look.
Your monthly energy costs drop. Tankless systems only heat water when you need it, which uses 25 to 40 percent less energy than keeping a tank of water hot all the time. For a typical Little Rock home, this saves $100 to $300 per year on utility bills.
You get cleaner water. Tank water heaters accumulate rust and sediment that sits in your hot water for years. Tankless systems have no storage tank, so fresh water gets heated every time. You're not using water that's been sitting in a rusty tank for days.
The system lasts much longer. A quality tankless water heater lasts 20 years or more with proper maintenance. Tank water heaters usually last 8 to 12 years before they rust through and leak. Over time, tankless systems cost less because you replace them half as often.
You increase your home's resale value. Buyers appreciate energy-efficient features and modern appliances. A tankless water heater is a selling point that sets your home apart from others on the market.
What to Expect When You Call for Tankless Water Heater Installation
We start by discussing your household's hot water needs. How many people live in your home? How many bathrooms do you have? Do you run multiple showers at once? Do you have a large bathtub you like to fill? These questions help us size the tankless unit correctly.
We schedule a site visit to evaluate your home. We need to see your current water heater setup, check your electrical panel capacity, examine your gas line size if you have gas service, and figure out where the tankless unit should go. This evaluation takes about 30 to 45 minutes.
We'll explain your options - electric versus gas tankless. Electric tankless heaters work anywhere but require significant electrical upgrades in most homes. They need dedicated high-amperage circuits that many older electrical panels can't handle. Gas tankless heaters are more powerful and can heat more water at once, but they need proper gas line sizing and special venting to the outside.
For electric installations, we often need to upgrade your electrical panel or add circuits. Little Rock homes built before 2000 typically have 100-amp or 150-amp panels. A whole-home electric tankless heater might need 150 to 200 amps total, which means upgrading your panel. We coordinate with licensed electricians to handle this work.
For gas installations, we evaluate your existing gas line. Many homes have half-inch gas lines that work fine for tank water heaters but can't supply enough gas for a tankless unit. We might need to run a larger three-quarter-inch gas line from your meter to the tankless location.
We give you a complete estimate covering the tankless unit, installation labor, and any electrical or gas line upgrades needed. Tankless installation costs more than tank replacement because of these extra requirements, but the long-term savings make up for it.
The actual installation takes one to three days depending on what prep work we need. Simple replacements in homes already set up for tankless can happen in one day. Installations requiring electrical panel upgrades or gas line work take longer.
We remove your old tank water heater first. We drain it, disconnect all the water lines, and haul it away. This creates the space we need for the new tankless unit and associated piping.
We mount the tankless unit on the wall in the best location. This might be where your old tank was, or we might move it to a better spot. Gas tankless units need outdoor venting, so we consider where the vent pipes can run through your wall or roof.
All the water connections get replumbed to fit the tankless unit. The inlet and outlet connections are different from tank heaters, so we install new pipes and valves. We also install isolation valves that make future maintenance easier.
For gas units, we connect the gas line and install proper venting. The venting is specialized - it brings in combustion air from outside and vents exhaust gases safely away from your home. This is required by code and ensures safe operation.
For electric units, we make the electrical connections to the dedicated circuits. Tankless electric heaters use 240-volt power like tank heaters, but they draw much more amperage. The wiring must be properly sized and protected.
After everything is connected, we test the system thoroughly. We run hot water at multiple fixtures to make sure the unit heats properly and maintains temperature. We check for leaks, verify gas connections are tight, and confirm the venting is working correctly.
We show you how to use your new tankless water heater. Most units have digital controls where you set the exact water temperature you want. We explain any maintenance requirements like annual flushing to prevent mineral buildup.
We provide warranty information and maintenance recommendations. Most tankless manufacturers offer 10 to 15-year warranties on the heat exchanger and 5-year warranties on parts. We explain what's covered and what maintenance you need to do to keep the warranty valid.
What to Expect When You Call for Tankless Water Heater Installation
When you call about tankless water heater installation, we discuss your hot water needs. How many bathrooms? How many people? Do you run multiple showers at once? Tankless heaters provide unlimited hot water but have limits on flow rate.
We figure out what size unit you need. We check if your gas line is big enough for a gas tankless, as they need more gas than tank heaters. For electric tankless, we make sure your electrical service can handle it, as they draw a lot of power.
We remove your old tank water heater and prepare the location. Tankless units mount on walls and take up way less space. We run new gas lines or electrical if needed. We install proper venting for gas units - they need different venting than tank heaters.
We mount the unit, connect everything, and program it. We test it by running hot water at multiple fixtures. We make sure it keeps up with your demand. We explain how it works - you have unlimited hot water but you can't run ten showers at once. We set the temperature and show you the controls.

Why Local Matters
For Your Plumbing
Why Local Matters
For Your Plumbing
You could call a big national chain. They'll probably charge you more and send someone who doesn't know Little Rock. Local plumbers understand that homes in Pulaski Heights have different plumbing than new builds in West Little Rock. They know which neighborhoods have hard water problems and which areas tend to have foundation shifts that affect plumbing.
When you call a local company, you get someone who answers the phone and can usually tell you right away what's probably happening and when they can get there. No automated system. No waiting on hold for 20 minutes.
Response times are better too. A local plumber is 15 minutes away, not coming from another city. If you've got a burst pipe or sewage backing up, those minutes matter. Plus, local companies know the city inspectors, understand Little Rock's specific codes, and can get permits processed faster. When you need plumbing work done right and done quickly, local is the way to go.
