Domestic hot water is so easy to take for granted, until it is gone. There are very things more enjoyable or necessary than a hot bath or shower. It is truly one of the best parts of modern life. However, traditional indoor water heaters are big, bulky, take up a ton of indoor space, waste a lot of energy keeping the water hot, and if you use too much hot water at once, they will run out. You then have to wait for it to refill and heat the water before you can start using hot water again. Stand by losses are the biggest waste of energy in homes with a traditional residential water heater. Stand by loss is the energy used keeping the water in the domestic hot water heater hot. The larger the unit the more hot water you have before it runs out, but the more energy it takes to heat and keep that water hot, increasing your energy bill and standby losses. Not to mention the larger the unit is, if you do run out of hot water the longer it will take to refill and heat it. These are a few of the main reasons why so many people today whether for a new home or if replacing an existing indoor residential water heater are choosing to buy the best much more compact and energy efficient Rheem on-demand indoor tankless inline water heater for their whole home’s domestic hot water needs over an outdated, bulky, energy and money wasting tank.

How Do Tankless Domestic Hot Water Heaters Save Energy and Provide Endless Hot Water

What To Consider Before Buying an Indoor Residential Tankless Water Heater

When buying a small, compact and energy efficient powerful whole home or small point of use indoor Rheem inline tankless water heater it is extremely important that it is sized properly. The colder the incoming water temperature is, and the more hot water used at the same time, the more energy it takes to heat that volume of water to your desired temperature. Temperature rise is the term used to describe the difference between incoming water temperature and what you want the outgoing water temperature to be. Flow rate is the term used to describe how much hot water is used at once. To make sure you buy the best Rheem indoor residential tankless on-demand water heater for you and your home, you will need to know what your desired temperature rise and at most how much hot water would be used at once.

It does not matter how much hot water is used throughout the day. As previously mentioned, high quality inline tankless water heaters heat the water you are using on-demand as you are using it, so you never run out of water. However, the more hot water being used at the same time, the greater the flow rate becomes, water is traveling through the unit faster, which means water has less time in the inline unit’s heating element to get hot, the more energy it will take to heat the volume of water to your desired temperature. Before buying a high quality energy star rated Rheem residential indoor endless hot tankless water for sale you want to make sure the large whole home system or small point of use inline unit will provide the temperature rise you want and the max flow rate you would ever need. As long as the top-rated, compact, and energy efficient Rheem on-demand indoor tankless water heater or multiple unit system you buy is sized properly it does not matter your climate, altitude, or how much hot water will be used at once you will be very happy with your space and money saving endless hot indoor residential water heater.
