Solar Water Heaters – A Practical and Eco-Friendly Water Heating Solution

Although the traditional electric water heaters and the tank-less water heaters have been quite popular among homeowners, but these units are also responsible for releasing the highest rates of carbon dioxide (CO2) into the environment. On the other hand, solar water heaters produce lower levels of greenhouse gas emissions that ultimately reduce your carbon footprint once it gets installed.

So if you are considering to replace your conventional electric water heater with a modern solar water heater, then take a look at the various aspects of the solar unit below to take the most eco-friendly decision for your home.

What are solar water heaters?

Solar water heaters are an eco-friendly heating system that source their energy from sunlight which they gather from solar panels. The solar energy hence gathered is then converted into heat and transferred to a water tank, which then warms the water supply of your home effectively. Solar water heaters are the best choice when it comes to an eco-friendly and energy efficient water heater option as these operate on a natural renewable energy source that requires no burning of coal or fossil fuels.

How does a solar water heater works?

Although the modern solar water heaters have simple construction, but their functionality is a complex as it incorporates sophisticated system of pumps, storage containers and collection devices. These water heaters are designed intricately for maximizing the sunlight collection and converting it into heat for stored water.

What are the pros and cons of solar water heaters?

Just like any other device, solar water heaters come with some pros as well as cons. So let us have a look at a few of them below:


Prevents Pollution

One of the most significant benefits of a solar water heating system is that it relies upon the natural renewable resource i.e. sunlight. As long as the sun keeps shining, you will get an endless supply of heat energy without burning coals or using fossil fuels, hence is an eco-friendly solution free from pollution. According to many researches it has been concluded that solar water heating does not generate any greenhouse gases or any other toxic pollutants. Also, it has been found that a solar water heater has the potential to prevent more than 50 tons of CO2 emissions from entering the atmosphere during a 20 year period.

Saves Significant Energy Cost

When you switch to solar powered water heating system from your conventional water heater, you will save a significant amount of energy cost which typically pays for itself within a 4 to 8 years span. Solar water heaters can last from 15 years to 40 years without needing traditionally sourced and expensive electricity.

Needs Low Maintenance

Solar water heaters once installed require minimal maintenance. But saying that, all hot water heaters and solar system storage tanks need an annual flush for expelling out all of the accumulated sediment at the bottom of the tank. Long term corrosion is one of the primary issues that any plumbing system experiences, hence, you still need regular maintenance to keep the solar water heater last as longer as 35 years or more before seeking any major part replacements.


Depends on the Weather

One of the major drawbacks of solar water heaters is that these devices completely depend upon the weather. Your area might not have the ideal geographic location for a solar powered system. If you reside in an area that experiences more gray days then you should keep a backup heater ready for those sun-less, dull days ,weeks and seasons.

Upfront Cost is on the Higher End

It is true that solar energy is free but harnessing and using it for your home comes at a higher cost. Initially you will have to pay more to save more in the long run.

However, when looking at the long term goals, the pros of solar water heaters overpower the cons.
