You may never have considered a tankless water heater or even know much about them. But before you get your next water heater, you might want to take the time to learn about tankless water heaters. R-Mech St. Louis is a local company that wants to help you in the decision making process for your new water heater system.

R-Mech offers Rinnai Condensing tankless water heaters. They 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, water enters the tankless water heater. A sensor detects the water flow and activates an electric or gas heating device, which quickly raises the water temperature to a preset level. When water flow stops, the heating element shuts off. Thermostatically-controlled tankless water heaters vary their output temperature according to water flow rate and inlet water temperature.

Tankless water heaters can help you enjoy up to 40% energy savings, endless hot water and significant space savings. Unlike traditional storage tank water heaters, Rinnai tankless water heaters do not store a reservoir of hot water. As a result, standby losses are reduced, which makes them an energy-efficient alternative to traditional water heating. When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they shut down and use no energy. There will always be hot water - endless hot water - for bathing, cooking, dishes, laundry and all the other countless ways hot water enriches our lives.

Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside. 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 longer - possibly more than 20 years, compared with 10-15 years for traditional heaters. Also, because they are not heating 40 - 50 gallons of water 24 hours a day, tankless water heaters are less susceptible to leakage than tank-type water heaters.
