Endless Supply of Hot Water

Tankless Water Heaters provide an endless supply of hot water. The popularity of oversize tubs is growing, and so is the demand for large volumes of low-cost hot water. The Rheem Tankless provides a compact solution for a continuous supply of energy-efficient hot water that won't run out.

Energy Savings of up to 50%

Your water heater is the second largest consumer of energy in your home after home heating/cooling. Therefore, it is where you can significantly reduce the costs of your annual energy consumption. Why keep a storage tank full of hot water 24 hours a day when the average household use is less than one hour per day? Depending on the model you select, tankless water heaters can provide endless hot water in homes with 1, 2, 3 or even more bathrooms. When water is heated and stored in a tank the inside walls will soon begin to build up mineral deposits. The scale build-up on the bottom of the tank can cause it to decrease in efficiency by as much as 50% over 10 years and the subsequent corrosion of the tank's inside wall will eventually cause it to leak. Compare this to a tankless water heater which does not store water and maintains its efficiency for the lifetime of the unit.

Significant Space Savings

Good things do come in small packages. Sophisticated technology has reduced the size and increased the features and benefits. Rheem Tankless is about one third the size of a conventional water heater, allowing room for a water softener or extra storage. A digital display makes setting a precise water temperature, or monitoring the units status, a snap!
