New Tankless Water Heaters in Metro Kansas City

Natural gas or propane fired tankless water heaters are compact heating units that provide hot water as it is needed and do not store hot water like traditional tank-type water heaters. When a hot water tap is turned on, a sensor detects the water flow and activates the tankless heater, which quickly raises the water temperature to a preset level.

Because tankless heaters do not store water, they are less subject to corrosion than tank-type heaters. As a result, their expected equipment life is possibly longer, typically more than 20 years, compared with 10 - 15 years for traditional heaters.

R-Mech Heating, Cooling and Plumbing are Kansas City's oldest and most experienced Rinnai tankless water heating expert. We have offered Rinnai high-efficiency water heaters to Kansas City, Independence, and Liberty, Missouri, and Overland Park, Kansas homeowners and businesses for more than almost two decades.
