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.
