You may be surprised to know that heating water to take a shower, wash dishes and etc. is the third largest energy cost for most homes.  Installing an eco friendly water heater can help you cut down on your energy costs significantly, which will save you money as well.  So, if you want to save money and energy, here are the top 3 eco friendly water heating options. 

Install a Tankless Water Heater

Installing a tankless unit to replace a traditional unit is a popular option.  Most tankless heaters are very energy efficient.  With a traditional unit, an entire tank of water has to be heated every time you want hot water, even when you only use a small amount of water. 

With a tankless unit, only the water that you need will be heated, saving a ton of energy.  In fact, you could save between 30%-50% on your energy costs by using this eco friendly option.  There are several quality brands including Bosch, Rheem, Rinnai and more.  Some models are more efficient than others, so you may want to look for an Energy Star rating. 

Install a Solar Water Heater

If you live in an area that gets lots of sun, installing a solar water heater can be a great eco friendly heater option.  Using the sun to heat water can be the most energy efficient solution.  However, there are some downsides. 

First of all, solar units can be expensive to purchase and install.  Secondly, if you don’t get adequate sunlight to power your water heater, you’ll need to use a secondary heating source.  On the upside, since solar heaters use the sun, they can be very affordable to run, so this may be a good option for you.

Improve Your Existing Water Heater

If your existing unit is only a few years old or you don’t have the budget to spend on a more eco friendly one, replacing your existing unit with a new solar or tankless water heater may not be the best option for you.  The good news is that there are still a few ways that you can reduce your water and energy costs without replacing your existing unit.

o    Use low flow faucets and showerheads – If you can’t switch to an eco friendly water heater, consider switching to low flow faucets and showerheads.  You’ll use less water and energy without sacrificing water pressure.

o    Fix any leaks immediately- While it may seem like one small drip of water, that small drip can lead to gallons of water lost over the course of several months, so make sure to get any leaks fixed as soon as possible to avoid losing more water.

o    Wash full loads of dishes and clothes- You can save a lot of hot water and energy over time by making sure that your dishwasher and clothes washer are completely full before you wash a load.

Installing an eco friendly water heater like a tankless or solar unit are definitely great options.  However, you can be more eco friendly with your existing water heater if you make a few adjustments.
