Overview

Product Overview

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.

Manufacturer Warranty

Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.

Professional Installation Recommended

Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.

Before You Order

Make sure it is the right size, and that you have the rest of it

Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
