Thinking About Going Tankless?
A tankless water heater can be an excellent upgrade—but the biggest benefits come from choosing the right system and installing it correctly. Unlike a traditional water heater that continuously keeps a stored tank of water hot, a tankless system heats water as your home needs it. That can mean more usable hot water, less space devoted to a bulky storage tank, and improved energy efficiency.
Continuous Hot Water
A properly sized tankless system can keep producing hot water as long as your household needs it. No more planning everyone's showers around a limited tank of heated water.
Lower Energy Waste
Because the system heats water when there is demand rather than maintaining a full tank around the clock, tankless technology can reduce standby energy loss.
More Usable Space
Tankless water heaters mount to the wall and take up substantially less room than traditional storage tanks, making them especially useful in garages, utility rooms, closets, and other tight spaces.
Built for Long-Term Performance
Tankless systems are designed for years of service, but proper installation and routine maintenance matter. Correct sizing, venting, water quality, gas supply, and regular descaling all play a role in how well the system performs over time.
Not sure whether tankless makes sense for your home?
We'll compare your hot-water demand, current plumbing setup, installation requirements, and budget before recommending a system.
Tankless Water Heater Installation
A great tankless system starts with more than choosing a brand or model. The system has to match the way your home actually uses hot water.
AZERPLUMB installs tankless water heaters for homeowners who want dependable hot water, improved efficiency, and a system built around their household—not a generic recommendation.
Before installation, we evaluate your current plumbing setup, hot-water demand, available fuel source, venting requirements, installation location, and the number of fixtures that may be used at the same time. That allows us to recommend a system with the capacity to keep up without unnecessarily oversizing the equipment.
Proper Sizing Matters
Tankless water heaters are rated by how much hot water they can produce at a given time. A system that works perfectly for a smaller household may struggle in a home where multiple showers, sinks, and appliances frequently run together.
We look at your household's real usage so the system is sized for peak demand—not just square footage.
Installation Built Around Your Home
Depending on the property and the system selected, installation may involve updates to gas supply, water connections, venting, condensate drainage, electrical connections, or mounting location.
Our plumbers evaluate those requirements before work begins so you understand what the installation involves and why.
Replacing an Existing Tankless System
If your current tankless water heater is aging, unreliable, or no longer keeping up with your household, we can evaluate whether repair or replacement makes more sense.
When replacement is the better option, we’ll help you select a new system that fits your current needs and install it properly for long-term performance.

TANK-TO-TANKLESS CONVERSION
Converting From a Tank Water Heater to Tankless
Replacing a traditional storage-tank water heater with a tankless system can be a major upgrade, but it isn't always a simple one-for-one equipment swap.
A tankless conversion changes how your home produces hot water, which means we need to evaluate more than the old water heater itself.
AZERPLUMB looks at the complete installation so you know what your home needs before the conversion begins.
Can My Home Be Converted to Tankless?
In many cases, yes.
The first step is determining whether your existing plumbing, gas or electrical service, venting options, and installation location can support the tankless system your household requires.
For gas-fired tankless systems, the higher demand of the new equipment may require changes to the gas supply. Venting can also be different from a traditional tank water heater. Depending on the model and location, condensate drainage and electrical connections may need to be addressed as part of the project.
That is why we evaluate the home first instead of simply removing the tank and hanging a new unit on the wall.
What We Check Before a Tankless Conversion
Hot-Water Demand
How many showers, sinks, tubs, and appliances could need hot water at the same time?
Fuel and Gas Supply
Can the existing gas system properly support the equipment being considered?
Venting
Where can the new system safely vent, and what changes are required for the selected unit?
Installation Location
Where will the tankless water heater provide the best combination of performance, accessibility, and serviceability?
Water Quality
Hard water and mineral buildup can affect tankless performance, so we consider maintenance needs when designing the installation.
Existing Plumbing
We check the current connections and surrounding plumbing for anything that should be addressed during the upgrade.
What Happens to the Old Water Heater?
As part of the conversion, the existing storage tank is disconnected and removed so the space can be reconfigured for the new system.
Because tankless units mount to a wall, homeowners often gain valuable floor space after the conversion—especially in garages, utility rooms, and mechanical closets.
Is a Tankless Conversion Worth It?
That depends on the home.
For some households, the biggest advantage is having a system that can better support long periods of hot-water demand. For others, the appeal is efficiency, additional usable space, or replacing an aging tank before it fails.
We’ll walk you through the installation requirements, expected benefits, and available options so you can decide whether converting to tankless makes sense for your home.

Frequently Asked Questions
How does a tankless water heater provide hot water on demand?
Tankless units heat water directly as it flows through the system using either electric elements or gas burners. That means you get hot water when you need it, without waiting for a large tank to fill or reheat. It's instant, efficient, and space-saving.
Is a tankless water heater really more energy efficient?
Yes, tankless systems are incredibly energy efficient because they only operate when there's a demand for hot water. Unlike conventional water heaters that keep a tank hot 24/7, these units reduce energy costs by eliminating standby heat loss. Over time, that adds up to real savings on your utility bills.
Can a tankless water heater handle a large household?
Absolutely! The key is choosing the right size unit to match your household's water use and simultaneous fixture needs. We help you find tankless water solutions that ensure you never run out of hot water, even when showers and laundry run at the same time.
How long does it take to install a new unit?
Most tankless water heater installations can be wrapped up in just one day. Our experienced plumbing services team works efficiently to ensure your home gets back to normal fast, with minimal interruption and maximum results.
What are the signs you need tankless water heater repair?
Watch out for inconsistent water temperature, blinking error codes, or a total lack of hot water—these are common red flags. If your unit makes odd noises or fails to deliver when needed, it's time for a tankless water heater repair by a professional.
Is it expensive to switch from a traditional to a tankless system?
The installation costs can be higher than replacing a traditional unit, but it's an investment with long-term rewards. You'll save on energy bills, enjoy fewer repairs, and benefit from extended system life. Plus, rebates and incentives may help reduce upfront costs.
Can you replace a tank system with a tankless system on your own?
We don't recommend it—installing a tankless water heater involves complex electrical work, gas line adjustments, and plumbing repairs. A licensed plumber ensures everything meets safety codes and runs efficiently from day one.
Will you need to change your water lines?
Not necessarily. Many setups are ready for an upgrade, but we'll inspect your system and let you know if any adjustments are needed. Our goal is to make the installation process as smooth and stress-free as possible.
Do you offer emergency repairs?
Yes, we do! If you've got a breakdown, cold shower, or error alert flashing on your unit, our team offers fast emergency service. We'll restore your hot water in no time.
What should you do if your tankless water heater keeps shutting off mid-shower?
If your tankless water heater suddenly shuts off during use, it could be due to improper venting, a dirty flame sensor, or even low water pressure. It's best to stop using the unit and schedule a professional inspection to prevent damage or safety hazards.
Can you install a water softener to help your tankless system last longer?
Yes, and it's a smart move—especially if your home has hard water. A water softener reduces mineral buildup inside the unit, helping you avoid scale-related issues and extend the life of your tankless water heater.
