Get Endless Hot Water with Maximum Efficiency – Upgrade to the ThermoMate CZ480NG Condensing Tankless Water Heater and enjoy unlimited, on-demand hot water for your home. With a 5.28 GPM flow rate and 114,000 BTU output, this advanced system delivers hot water to 3–4 fixtures simultaneously – perfect for busy households. Say goodbye to cold water shocks and waiting for the tank to refill.
Save Energy & Reduce Utility Costs – This condensing tankless water heater achieves a high 0.86 UEF efficiency, offering up to 15% energy savings compared to non-condensing units. Its innovative dual heat exchanger system combines a corrosion-resistant stainless steel condensing exchanger with an oxygen-free copper heat exchanger to capture and reuse heat normally lost by traditional water heaters, maximizing energy efficiency and minimizing operating costs.
Smart & Precise Temperature Control – The ThermoMate CZ480NG uses an advanced flow sensor and microchip technology that adjusts heating power 20,000 times per second, keeping hot water fluctuations within ±1℉. The 3.5-inch LED touchscreen allows easy adjustment of water temperature (90°F–140°F) and real-time monitoring of water flow, flame status, and fan operation.
Safe & Reliable Performance – Engineered with 8 comprehensive safety protections, including boil-dry, freeze, flame-out, overheating, over-temperature, pipe blockage, high-temperature lock, and excessive air pressure safeguards. The water heater’s auto frost protection activates below 41°F (5℃), using minimal electricity to prevent frozen pipes.
Compact & Easy to Install – Measuring 21"H x 13"W x 7"D, this wall-mounted unit saves more than two-thirds of the space of traditional tanks. With standard 3/4" NPT water connectors, 1/2" NPT gas inlet, 3" vent, and UL-approved 120V plug, installation is simple and compatible with most homes.
Condensate Management – As a condensing unit, the CZ480NG produces mildly acidic condensate water. For optimal pipe protection, we recommend installing an external condensate neutralizer kit (sold separately) to neutralize the acid.
Built for Extreme Weather – Equipped with a high-speed DC fan (380Pa static pressure/6000 RPM), this water heater ensures safe and powerful exhaust evacuation, capable of withstanding winds over 111 mph (Category 3+ hurricane conditions), preventing backdraft or flameouts.

Easy install took less space works good
After old heater tear out and repiping, installation was easy.
After doing tons of research, I chose the CZ480NG for the 0.86 UEF efficiency. It’s been running for two months now and works flawlessly. Hot water comes instantly and doesn’t fluctuate. I also installed the condensate neutralizer kit as recommended – very easy to set up.
This heater is powerful but compact. It fits neatly on my basement wall and freed up a lot of space. I love that it shows real-time information on flow rate and flame status – feels high-tech and reliable. No more waiting for hot water, which is a blessing with two teenagers at home.
We have a family of five, and this tankless water heater has been a game changer. It easily handles two showers and the dishwasher running at the same time. I was skeptical about the condensing feature at first, but I can already see the difference in my gas bill. Excellent product!
I replaced my old 40-gallon tank with the ThermoMate CZ480NG and the difference is night and day. Showers no longer run cold when someone uses the kitchen sink. The installation was straightforward, and the size is so compact compared to my old tank. I also appreciate the precise temperature control – it really keeps the water steady. Highly recommend!
I live in a colder climate and worried about freezing, but the built-in frost protection works perfectly. Even during sub-zero nights, we had no issues. The unit is quiet, efficient, and the digital display makes it easy to adjust settings. Great investment for long-term savings.
we like it , i just want to say very very good
Great unit. Works as advertised. Install was at a homeowners level. Great performance for the price.
Tank gets installed tomorrow. Replacing a State Select condensing 50 gal heater purchased in 2004. Will update this once nee unit is installed snd operational .
Awesome!
It started up immeadiately and gets the water hot quickly. VERY easy install. my only complaint is that if the water flow is lower than full blast, it will shut off... leaving you in the cold.
I recently upgraded to the ThermoMate CZ480NG Condensing Tankless Water Heater, and it’s been a total game changer for my home. The hot water is instant and consistent — no more running out of hot water during showers or while doing laundry and dishes at the same time. With a 5.28 GPM flow rate, it easily handles 3 to 4 fixtures running together.
I was nervous about switching to a tankless system, but this product exceeded expectations. It’s compact, quiet, and delivers endless hot water even when multiple taps are running. I especially like the safety protections – makes me feel secure knowing the system looks after itself.
Very impressed with the build quality. It’s lightweight but feels sturdy. The 114,000 BTU output is more than enough for our household needs. The installation kit had everything needed, and the manual was clear. It’s been reliable since day one.
The energy savings are real. My utility bill dropped noticeably since switching from a non-condensing tankless model. The stainless steel and copper dual heat exchangers feel like solid, durable engineering. This unit gives me peace of mind knowing I won’t run out of hot water again.
