Tankless water heaters can be a game-changer, but only when installed where they make sense. A tankless system may be a great fit if:
You Have a Growing Family or Frequent Guests
Running out of hot water is a common headache in busy homes. With a tankless system, hot water is heated on demand so everyone can shower, run the dishwasher, and do laundry without timing everything just right.
Your Current Water Heater Is Reaching the End of Its Lifespan
Older tanks lose efficiency and are more prone to breakdowns, leaks, and corrosion. Upgrading to a tankless system can save you from an emergency replacement and give you peace of mind for years to come.
You’re Remodeling or Upgrading Your Plumbing System
If you’re already doing work on your home, it’s the perfect time to go tankless. These systems are compact and wall-mounted, freeing up space and fitting seamlessly into modern plumbing layouts.
You Want to Avoid Unexpected Water Damage
With a tankless water heater, you’ll never have to worry about an old storage tank corroding or bursting and flooding your home. Enjoy peace of mind knowing your hot water system is not only efficient but also eliminates the risks of tank failure and water damage.
Not Sure Yet? That’s What We’re Here For.
Our job isn’t to sell you something you don’t need; it’s to help you make the best decision for your home. JG Water Heaters, Filtration and Plumbing walks you through your options, explains the pros and cons, and helps you understand what’s possible with your current setup.

Standard Tankless Units
Reliable, Efficient, and Built for Everyday Comfort
Our standard models offer dependable, high-efficiency performance and are ideal for most homes. They're especially popular for remodels and upgrades from old tank systems.
- Unlimited Hot Water on Demand: No more running out mid-shower or waiting for the tank to refill.
- Energy Efficient Operation: Uses energy only when you turn on the faucet, saving money annually.
- Compact, Wall-Mounted Design: Frees up space in your garage, closet, or utility area.

- Great for Larger Tubs: Heats continuously so you can fill deep tubs with ease.
Standard tankless water heaters are available for both 1–3 bathroom and 4+ bathroom homes, depending on the flow rate needed.
Advanced Tankless Units
Faster Hot Water With Built-In Smart Tech
Advanced units include enhanced features for those who want even more comfort and efficiency, which is especially helpful in larger homes or for those who value convenience.
- Recirculating Technology: Built-in pump reduces wait time at distant faucets or showers.

Tankless Water Heater Installation You Can Count On, From Start to Finish
When you choose JG Water Heaters, Filtration and Plumbing for your tankless water heater installation, you get a quality product and a full-service experience that puts your comfort and convenience first. From the moment you call to the final walkthrough, we handle every step with care, clarity, and craftsmanship.
Here’s how we make the tankless water heater installation process smooth, stress-free, and built around your home’s unique needs:
1. In-Home Evaluation
Every home is a little different, so we start with a quick, thorough assessment. We’ll look at your existing plumbing setup, check your gas line or electrical system, and ask about your household’s water usage. This helps us determine if a tankless water heater is the right fit and exactly what’s needed to install it safely and efficiently. If your old water heater is already on its last legs, we’ll prioritize a quick turnaround to minimize downtime.
2. Personalized System Recommendation
Not all tankless systems are the same. We’ll help you choose the right size, model, and fuel type (gas or electric) based on your home’s layout, family size, and budget. We only recommend trusted brands we’ve personally installed and stood behind for years.
3. Clear, Upfront Quote
Once we know what your home needs, we’ll walk you through a detailed quote so there are zero surprises. We’ll explain everything we recommend, always with your best interest in mind. We believe in transparency, not pressure. You’ll have the info you need to make a confident decision.
4. Professional Tankless Water Heater Installation
If you’re ready to move forward, we’ll get your new system installed, often the same or the next day. Our licensed, experienced plumbers will handle everything: removal of your old unit, proper setup of your new tankless heater, system testing, and a clean finish. We work efficiently, protect your space, and treat your home with care.
5. Post-Install Support
We’ll walk you through how your new system works and answer any questions before we leave. And if anything comes up later or you just want to check in, you can count on us to be there. Our service doesn’t stop at the install; we’re your go-to for future maintenance, repairs, and replacement.

The Benefits of Going Tankless
Upgrading to a tankless water heater isn’t just about getting hot water—it’s about getting more from your home, too. More comfort, more savings, more space, and more reliability. Here's what makes going tankless a smart move for so many homeowners:
Endless Hot Water
Say goodbye to cold showers and scheduling around the water heater. A tankless system heats water on demand, which means you’ll never run out with a properly sized unit, even with back-to-back showers, laundry loads, or dishwashing marathons. It’s hot water when you need it, for as long as you need it.
Energy Efficiency That Pays Off
Traditional water heaters keep a tank of water hot 24/7, whether you're using it or not. Tankless systems only fire up when you turn on the tap, making them significantly more efficient. Over time, that means lower monthly utility bills and less energy wasted heating water you never use.
Compact, Space-Saving Design
No more bulky tank taking up floor space in the garage or closet. Tankless water heaters mount neatly on the wall, opening up room for storage, tools, or just a cleaner, more modern setup. They’re great for smaller homes, remodels, and anyone who values efficiency and aesthetics.
Longer Lifespan
A well-maintained tankless system can last 20 years or more, outliving traditional tank models by 5–10 years. That means fewer replacements, fewer headaches, and a better return on your investment.
Boosted Home Value
Today’s homebuyers are looking for energy-efficient upgrades, and a tankless water heater installation checks all the boxes. They’re a desirable, future-ready feature that can make your home more attractive on the market if you ever decide to sell.
What Our Customers Say
Here are just a few of the great things our clients have said about us.
Excellent service with a level of honesty and integrity we have not experienced with other companies. Very impressed and grateful. When it DOES come time for us to replace our water heater, we will use JG.
Neighbor was having water heater installed, and we had been researching and getting bids/reviews. The installation Technician (Christian) gave us a bid, and told us they recommended, Bradford White. We asked how soon they could install a 50-gallon unit, and to our surprise he had one on his van. He installed the water heater, and replaced all ball valves for shut-offs. Very happy with the price, efficiency and quality of the work performed. Friendly and professional!
I called JG Water Heaters the morning after my 75 gallon gas water heater started leaking. Gregg came out right away and by 5pm his 3-man crew had installed a new tankless one along with all additional per-code gas line and new exhaust. They also changed out the old, faulty water pressure regulator that probably contributed to the leak. Great team. 120% great workmanship, supported by excellent leadership and infrastructure. Pretty perfect. Very highly recommended.
