Tankless Hot Water Heaters and How They Save You Money!


Though central and supplemental air conditioning and heating units are usually the main energy users in homes, hot water heaters often come in at a close second. Water heaters are used often throughout the day, from kitchens to bathrooms to garages. 

Whether you are looking for a new water heater to replace your existing unit or if you're just looking for a more efficient way to save energy, choosing the right model will really pay off, especially in the long run.

There are many different types of hot water heaters:

Which Type Is Best?

A solar-powered water heater may be the most energy efficient and most rewarding in terms of long-run usage, but there are also many factors that affect your ability to use one: your location, the weather, and even the direction your roof faces. As a result, most people prefer to use a tankless hot water heater.

As mentioned above, tankless water heaters, also known as "demand" water heaters, don't store the hot water in a reservoir. This gives you a constant and immediate supply of hot water whenever you need it. You don't have to wait for the cold water to slowly warm up, and as a result, your home can become 24 to 34% more energy efficient!

Most of these heaters, like those from Stiebel Eltron and Rheem, come with a number of safety features to make sure you and your family don't have to sacrifice safety to save money.

You'll need to determine what type of application you'll be using the tankless system for in your home. Is it for a single application? Then you'll need a point-of-use version. If you plan on using it for multiple applications, then you'd be better off with a whole house model.

3. Location & Size

The size unit you need is determined by GPM, and there are several factors that can help determine what is best for you. These include ground water temperature, desired hot water temperature and flow rate:
