Tankless Water Heater Installation inBuford, Georgia



Endless Hot Water and Lower Energy Use With Expert Tankless Installation

Running out of hot water halfway through a shower is a problem a tankless water heater can solve. Instead of storing and reheating a tank of water around the clock, a tankless unit heats water only when you open a tap. At Paramount Plumbing HVAC, we bring over 30 years of experience to every tankless installation, making sure your new system is sized, vented, and connected correctly from day one.


We proudly serve Buford, Georgia, and nearby communities, including Suwanee, Sugar Hill, and Flowery Branch. Homeowners across Gwinnett and Hall Counties count on us to review their hot water needs, the number of bathrooms, and the fixtures that run at the same time before recommending the right unit. Whether you are replacing an old tank in an established home or planning for a new build, our licensed team handles the planning and installation with care.


A tankless installation involves more than mounting a unit on the wall. Gas supply, electrical capacity, venting, water connections, and code requirements all affect how well the system performs and how long it lasts. By handling each detail with precision, Paramount Plumbing HVAC delivers an installation you can rely on for steady comfort, better efficiency, and lasting peace of mind.


Our Tankless Water Heater Installation Services

Gas Tankless Water Heater Installation

Gas tankless models deliver strong flow rates for busy households. We install the unit, connect and size the gas line, set up proper venting, and test combustion and operation, so your system runs safely and delivers consistent hot water whenever you need it.

Electric Tankless Water Heater Installation

Electric tankless units are a compact option for homes where gas is not available or preferred. We confirm your electrical capacity, handle the wiring and water connections, and calibrate the system for safe operation and dependable hot water at every fixture.

Tank to Tankless Conversion

Switching from a traditional tank is a smart upgrade for many households. We remove the old tank, adjust the plumbing, gas, venting, and electrical connections as needed, and install your new tankless unit, so you gain floor space and enjoy hot water on demand.

Sizing and Hot Water Demand Assessment

The right unit depends on flow rate and temperature rise. We review your household size, fixtures, and peak hot water use to select a tankless heater that keeps up with demand without wasting energy or leaving you with weak, inconsistent hot water.

Venting, Gas Line, and Electrical Upgrades

Tankless systems often have different venting and supply requirements than tank models. We upgrade or modify gas lines, venting, and electrical service where needed, making sure every connection meets code and supports safe, efficient performance for years to come.

Testing, Setup, and Homeowner Walkthrough

After installation, we test water temperature, flow, and safety functions, then walk you through the controls and routine care. You will know how your new system operates, how to adjust settings, and what upkeep keeps it running efficiently.


Benefits of Professional Tankless Water Heater Installation

Steady Hot Water Supply

A properly sized tankless water heater heats water as you use it, so you are not limited by the size of a storage tank. Professional installation ensures the unit matches your household demand, giving you hot water for showers, laundry, and dishes without waiting for a tank to refill.

Lower Energy Use

Because a tankless unit does not keep a full tank of water hot around the clock, it avoids standby heat loss. Correct installation and calibration help the system run at its rated efficiency, which can reduce energy use and utility bills over time.

Space Saving Design

Tankless heaters mount on the wall and take up far less room than a bulky storage tank. Expert placement and secure mounting free up floor space in your utility room, garage, or closet while keeping the unit easy to reach for service.

Longer Equipment Life

With proper care, tankless systems often outlast traditional tank models. Professional installation protects that potential by getting venting, water flow, and gas or electrical connections right from the start, which reduces stress on internal components and helps prevent early failures.

Safe, Code Compliant Installation

Gas lines, venting, wiring, and pressure relief all affect how safely a water heater operates. Our licensed team follows applicable code requirements and tests every connection, protecting your family and property from leaks, poor venting, and electrical hazards.

Reliable Performance From Day One

Professional setup means the system is tested and adjusted before we leave. You get consistent water temperature, quiet operation, and a clear understanding of how to use and maintain your new unit, so there are fewer surprises after installation.

Upgrade to Tankless With Confidence

Choosing a tankless water heater is a long term investment in comfort and efficiency, and the installation determines how well it performs. At Paramount Plumbing HVAC, we bring 30 years of experience to every project in Buford, Georgia, and nearby communities like Suwanee, Sugar Hill, and Flowery Branch. Our team plans carefully, installs precisely, and tests thoroughly, so your new system delivers reliable hot water for years. When you are ready to upgrade, we are ready to help you do it right.

FREQUENTLY ASKED QUESTIONS

  • How does a tankless water heater work?

    When you open a hot water tap, cold water flows into the unit, where a gas burner or electric element heats it instantly as it passes through. There is no storage tank, so you get hot water on demand without the standby heating a tank requires.

  • Are tankless water heaters worth the investment?

    For many households, yes. Tankless units typically cost more upfront but can reduce energy use, free up space, and last longer than tank models. Our team can review your home and usage to help you decide whether tankless fits your needs.

  • What size tankless water heater do I need?

    Sizing depends on how many fixtures run at the same time and how much the incoming water must be heated. We assess your household's peak demand, then recommend a unit with enough flow capacity to keep up without wasting energy.

  • Can a tankless water heater run several showers at once?

    Yes, if it is sized correctly. Every unit has a maximum flow rate, so a system chosen for your household can support multiple fixtures at the same time. An undersized unit may struggle, which is why proper sizing matters.

  • Do I need to upgrade my gas line or venting for a tankless unit?

    Often, yes. Tankless heaters usually need a larger gas supply and different venting than tank models, and electric units may need a larger electrical circuit. We inspect your existing setup and make the upgrades needed so the new system runs safely and meets code.

  • How long does a tankless installation take?

    Many installations are completed in a single day, though the timeline depends on the unit and the work involved. Gas line changes, new venting, or electrical upgrades can add time. We explain the scope of work before we start.

  • How long do tankless water heaters last?

    With regular maintenance, tankless water heaters commonly last 15 to 20 years, which is longer than most tank models. Annual flushing and descaling help protect the heat exchanger and keep performance consistent.

  • Can I install a tankless water heater myself?

    We do not recommend it. Installation involves gas, electrical, venting, and plumbing work with real safety risks, and mistakes can lead to code violations or warranty problems. A licensed professional makes sure the system is safe, efficient, and set up correctly.
