Outdoor Instant and Endless Hot Energy Efficient Tankless Water Vs. Traditional Gas Powered System 

There are very few modern comforts more beneficial or enjoyable than hot running water for showers, washing hands, dishes, bathes, laundry and other cleaning. It is easy to take your hot morning shower, or relaxing evening bath for granted, that is until you no longer have hot water. There is nothing worse than running out of or not having hot water. This is one of the main reasons why so many Americans are choosing the best, most energy efficient, instant and endless hot small exterior wall mounted, whole home Rheem outdoor installed gas powered tankless water heaters, over traditional hot water heating systems. Traditional gas water heaters run out of water after you use the volume of hot water it can hold. You then have to wait for it to refill and heat the new water. The larger the hot water heating system is, the more hot water it can hold. However, it also takes longer to refill and reheat. These types of residential gas-powered whole home water heaters are also not very energy efficient. They waste a ton of energy, because these gas-powered whole home water heaters have to continuously use energy keeping the water hot for when it is needed. This is called the stand by losses. For houses with traditional gas-powered water heating systems stand by losses are the biggest energy expense. Plus, these traditional water heaters are big, bulky, take up a ton of space and can only be installed indoors.  

Top rated, energy efficient, small, outdoor Rheem gas-powered tankless water heaters are installed outside. They are typically mounted on the outside of an exterior wall of the home. However, they are also often used for outdoor showers as well. Because the best Rheem outdoor tankless on demand water heaters are relatively small, they are easy to mount to any exterior wall. Having an exterior wall mounted Rheem instant and endless hot gas tankless water heater will prevent precious space inside the home from being wasted. Exterior wall mounted Rheem outdoor inline tankless water heaters are also much easier to install than traditional residential water heating systems. Unlike traditional whole home gas water heaters, the best Rheem tankless water heaters are small and easy to move around. Because energy efficient outdoor on-demand tankless water heaters are installed outside the home there is not any expensive or difficult venting involved.  To install, simply mount the small, energy efficient inline continuous flow Rheem outdoor gas tankless hot water heater on the outside of the house, on an exterior facing wall, using the easy mounting brackets and screws that come with the unit. You then have your water in, water out, gas connection, which is standard ¾” at the unit. However, top-rated Rheem residential gas outdoor on-demand tankless water heaters will get enough gas pressure off a half inch line or larger. The outdoor installed energy efficient space and money saving Rheem tankless hot water heaters also come with a 120-volt power cord, and come exclusively from TanklessWaterHeaterDepot.com with a pre-wired thermostat controller from Rheem.

In addition to saving space and being much easier and cheaper to install than traditional whole home residential hot water heating systems, the best Rheem outdoor gas continuous flow tankless water heaters are extremely energy efficient, completely eliminate expensive stand by losses and never run out of hot water. Unlike a traditional hot water heater, top rated small Rheem outdoor gas-powered tankless water heaters only heat the water that you are using as you are using it. This is why energy efficient inline tankless water heaters are often called on-demand hot water heating systems, because they only heat water on-demand as it is needed. The best Rheem tankless water heaters have heating elements with multiple chambers. When you turn on hot water in the house, water starts flowing through the outdoor wall mounted Rheem on-demand tankless water. This turns the unit on. (Rheem units only need .4 gallons per minute to turn on, which is a bathroom sink’s hot water turned on less than half way. Once on this can be reduced down to .1 gallons per minute) As the water flows through the powerful Rheem heating element water is heated to the desired temperature, with a max temperature of 140 degrees for the residential whole home and outside shower gas-powered Rheem exterior mounted inline tankless water heaters. This is also why energy efficient on-demand tankless water heaters are also commonly referred to as instant hot water heaters and endless or continuous hot water heaters. By heating the water that you are using as you are using it you completely eliminate the stand by losses, and never have to worry about running out of water. As long as you have gas, you will never run out of hot water.
