MRCOOL® Natural Gas Tankless Water Heater (MHWH199NCNU)


Unlike traditional water heaters, the MRCOOL® Natural Gas Tankless Water Heater provides neverending hot water to up to four bathrooms and multiple home appliances simultaneously. With a high volume and flow rate, this tankless heater is highly efficient while still being environmentally friendly. This compact and space-saving heater has a much longer lifespan thanks to the stainless steel, corrosion resistant engineering. This design has four times the corrosion resistance of copper and is lead free. One of the many high tech features of this unit is the electronic thermostatic PCB, which provides intelligent temperature control and gas flow that is automatically controlled. The EDM BLDC variable-speed fan provides stable combustion along with a smooth air flow transition. The combustion chamber is surrounded by water tubes making it a thermal insulator also. The environmentally-friendly premixed burner gives a reduction of NOx emissions, lowers the flame temperature, and reduces port-loading. You can experience the most comfortable shower experience thanks to the self-adapting temperature regulation. A large touch-screen display provides helpful information to you and your plumber about the heater’s operation. This unit must be installed by a professional and offers a 15-year heat exchanger warranty, a 5-year parts warranty, and a 5-year labor warranty. This MrCool® Natural Gas Tankless Water Heater will replace your old water heater and provide efficiency and effectiveness.

Super. Great. Awesome value

Had to buy adapters to fit United States imperial system measurements, and the display is in Celsius degrees, but other than that for the price I paid for the unit, and having continuous hot water, I am a VERY satisfied customer! Easy to install too.

good steady temp stream

I had to replace another heater that failed. My main problem with the former one is that lower flow rates led to it turning off and I had to adjust the temp a lot because colder winter water required a higher gas flow rate. This one has fewer adjustment valves. It just produces water at the set point. A huge improvement. Not as cheap as some but no headaches. Works like the super expensive brands.

Efficient and Reliable

I recently installed the Natural Gas Tankless Water Heater in my home, and it has been a game-changer! This unit provides an uninterrupted supply of hot water, and I no longer have to worry about running out, even during peak usage times. The installation process was straightforward, and the unit's compact design allowed it to fit snugly in a small corner of my utility room, saving valuable space. The build quality feels solid, and I'm confident it will last for years to come.

Energy-Efficient and Cost-Effective

I'm delighted with the energy efficiency of this natural gas tankless water heater. It only heats water on-demand, eliminating the energy loss associated with traditional water heaters that constantly maintain a heated tank. This efficiency translates into significant cost savings on my utility bills.
