Say goodbye to cold showers and hello to endless hot water with the EZ Ultra HE condensing tankless water heater. This is a high-efficiency natural gas model that can push efficiency up to 92% by using exhaust gases to preheat the incoming water—pretty smart, right? It delivers up to 3.4 gallons per minute (at a 45°F temperature rise), which is great for homes with one or two bathrooms. Because it's a condensing unit, the exhaust is cooler, allowing you to vent it vertically or horizontally using standard Schedule 40 PVC or CPVC pipe (up to 30 feet). The package includes a back-draft prevention device and a 28-inch stainless steel horizontal vent pipe for easier installation. It's fully automatic: just turn on the hot water tap, and it fires up; turn it off, and it shuts down. The digital display lets you monitor operation easily. The connections are 1/2\ NPT male for both water and gas. The unit itself is about 27\ x 14.5\ x 6.5\, so it's compact and saves space compared to a traditional tank heater. It's been tested extensively and is a solid choice if you're looking for consistent, on-demand hot water and want to upgrade to a more efficient system. Perfect for the DIY-minded homeowner or for professional installation.
