Gas and Electric Tankless Water Heater Options in Pinellas County
Tankless water heaters are available in gas and electric models, and the right choice starts with your home—not the brand. Your existing utilities, household size, and daily hot water demand all play a role in selecting a system that will provide reliable performance for years to come.
Gas Tankless Water Heaters
For homes with natural gas, McGill Plumbing installs Noritz and Rinnai tankless water heaters. These systems are designed to handle higher hot-water demand while delivering dependable, energy-efficient performance. If your home already has a gas connection, a gas tankless water heater is often the most practical option for larger households.
Electric Tankless Water Heaters
If your home doesn't have natural gas, an electric tankless water heater may be the better fit. We install Stiebel Eltron systems, which provide an efficient, space-saving solution for homes that rely on electric service. Electric models can be an excellent choice for smaller households, home additions, or properties where installing a gas line isn't practical.
Choosing the Right Tankless Unit for Your Pinellas County Home
Selecting the right tankless water heater involves more than choosing between gas and electric. Before making a recommendation, a McGill plumber will evaluate several factors, including:
Your household's size and daily hot water usage
Peak demand, such as running multiple showers or appliances at the same time
Existing gas or electrical service
Available installation space
Venting and plumbing requirements
If your home already has natural gas, installing a gas tankless water heater is often the most straightforward option. Homes without gas service may benefit from an electric model, although some installations require dedicated electrical circuits or an electrical panel upgrade. If gas line work is needed, our team can complete that as part of the installation.
Every tankless water heater installation is completed in accordance with Florida code, and we'll explain any additional recommendations (such as thermal expansion protection) before work begins. Our goal is to install a system that's properly sized, professionally installed, and built to deliver reliable hot water for years to come.
How Tankless Water Heaters Work
Unlike traditional water heaters that continuously heat and store water in a tank, tankless systems heat water only when you need it. When you turn on a hot water faucet, cold water flows through the unit's heat exchanger, where it's heated before traveling directly to your faucet or shower.
Because there's no storage tank, a tankless water heater eliminates standby heat loss—the energy used to keep a full tank of water hot around the clock. The result is greater energy efficiency, a continuous supply of hot water, and a compact design that frees up valuable space in garages, utility rooms, and closets.
With proper maintenance, tankless water heaters can last up to 20 years, making them a durable, long-term investment for many Pinellas County homeowners. If you're comparing your options, explore our water heater installation and repair services to learn more about traditional tank water heaters.
Tankless Water Heater Repairs in Pinellas County
A tankless water heater should deliver reliable hot water whenever you need it. If your system isn't performing as it should, prompt repairs can help restore efficiency, prevent further damage, and extend the unit's lifespan. McGill Plumbing repairs gas and electric tankless water heaters throughout Pinellas County, diagnosing the problem and recommending the most effective solution.
Some of the most common tankless water heater issues we repair include:
No hot water: Ignition problems, gas supply issues, or electrical failures can prevent the unit from heating water.
Inconsistent water temperatures: Fluctuating temperatures are often caused by flow sensor problems, mineral buildup, or a unit that's no longer operating efficiently.
Error codes: Modern tankless water heaters display diagnostic codes when something isn't working properly. We'll identify the cause and complete the necessary repairs.
Reduced performance from hard water: Mineral deposits can build up inside the heat exchanger over time, restricting water flow and reducing efficiency if the system isn't routinely descaled.
Because Pinellas County has naturally hard water, mineral buildup is one of the most common causes of tankless water heater problems. Installing a water softener can significantly reduce scale buildup, improve long-term performance, and help extend the life of your system. McGill Plumbing's water treatment team can recommend and install the right water softener to protect your tankless water heater and your home's plumbing.
Every tankless water heater repair is backed by a 90-day warranty on parts and labor, giving you added confidence in the work we perform.
What to Expect During Your Tankless Water Heater Installation
Installing a tankless water heater starts with a thorough assessment of your home's plumbing system, fuel source, and utility connections. This allows our plumbers to confirm the unit is properly sized, identify any installation requirements, and ensure your new system is set up for long-term performance.
On installation day, we'll complete the work in accordance with Florida plumbing code, test the system to verify everything is operating correctly, and walk you through its basic operation and maintenance. Before we leave, we'll answer your questions and make sure you know how to get the most from your new tankless water heater.
When you choose McGill Plumbing, you can expect:
Same-day scheduling for many installations and service calls
Upfront pricing with no hidden fees or surprise charges
A one-year McGill labor warranty, in addition to the manufacturer's warranty coverage

Hear From Our Happy Customers
McGill Plumbing and Water Treatment is a business with 3 generations of satisfied customers. Cody and Johnny were professional, knowledgeable and friendly. Highly recommend for any plumbing issues you may have.
I've been using McGill for nearly 20 years. It started with a stupid mistake that broke an outdoor faucet on a weekend and McGill was out quickly to fix the problem. Over the years they have replaced toilets and fixed other plumbing leaks, and are responsive. There's a reason they have been around so long! And Tonya is always great to work with, as well as the other employees I have encountered.
I am extremely happy with McGill Plumbing. They moved my plumbing from the floor to the attic. Jake and Bobby were professional, friendly, explained what they were doing, and very easy to work with. Kudos to McGill Plumbing. Reasonable price. Everything was upfront. No surprises. I would highly recommend.
Just an incredibly professional job installing my hot water heater by Mark. Old piping was a mess and he cleaned it all up with sweated(soldered) copper pipes! Same price or cheaper than the competition and they don’t solder copper. Can’t be happier.
I called McGill plumbing to fix a plumbing issue I was having. They scheduled someone to come to my house within 30 minutes. Chris from McGill addressed the problem and fixed it for me. He was very professional and kind.. I will continue to use McGill if I have anymore problems in the future.
