How to Choose a Efficient Solar Water Heater


Several factors come into play when choosing a Solar Water Heater. First of all, you need to decide how much you’re willing to spend on your solar water heater. You should consider the energy savings that you’ll get from having one installed. Next, you’ll want to consider the installation and maintenance process. Read on to learn more about solar water heaters. You’ll soon be surprised at just how affordable they can be.

Cost of Solar Water Heater

Investing in a solar water heater will reduce your carbon footprint, which is important if you want to help the environment. You can also save money on utility bills because your system will run off renewable energy, instead of burning fossil fuels. In addition, you can get tax credits from the federal government and many local governments offer incentives that lower the initial cost. And, of course, using renewable energy will increase the value of your home. More buyers are looking for homes that use less energy, and that higher perceived value translates into a higher asking price when you decide to sell your home.

Determine your location and solar resource

When calculating the cost of a solar water heater, you should first determine your location and solar resource. Also, consider the direction of sunlight and the climate where you plan to install it. You should also gather information about regulations, local subsidies, and tax exemptions. Once you’ve done this, you can start looking at solar water heaters and compare them. When comparing providers, look for those that have a good reputation.

Energy savings Heater

A widely used method of heating water is a solar water heater. These devices heat water by converting the sun’s energy into thermal energy. While this is an efficient method, it does require additional solar energy. The average solar hot water heater needs 2.2 kW, which is roughly the equivalent of seven additional solar panels. Because solar energy is expensive, it can add up to over $6,380 to the cost of the water heater.

Types of Solar Water Heater

There are two main types of solar water heaters: evacuated tube collectors and direct-current (DC) systems. The former use a series of transparent glass tubes or flat plates to collect the sun’s heat. The heat is then transferred to water stored in a tank or a conventional water heater. Unlike conventional water heaters, evacuated tube collectors can work even in cold temperatures. But before you install one of these devices, you should make sure that your climate permits it.


Installation of Heater

Installing a solar water heater requires proper orientation and plumbing lines. In addition to addressing these issues, this article provides a quick review of the components of a solar water heater. We’ll also provide tips to choose the best one for your home. Installing a solar water heater can save you money and energy.

Different cost by different factors

A typical system costs between $3,000 and $6,000. You can choose a 50-gallon or 80-gallon tank for this price. Larger systems are more expensive, as you’ll need more solar collectors. And remember, passive solar water heaters require fewer solar collectors and will pay for themselves within a few years. Solar water heaters are also more complex than traditional systems.

Maintenance of Heater

To maximize the power output of your solar water heater, it is essential to perform regular maintenance on it. You can do so with routine cleanings and checking of its parts. You can also opt to have an electric backup system for overcast days, but ensure to switch it off as soon as the day is over. This is because of the danger of galvanic corrosion which occurs when dissimilar metals come into contact with each other.

Easy to maintain a heater

The maintenance of a solar water heater is fairly simple. Cleaning the glass surface once every five days, preferably daily, will increase the efficiency of the system. You also need to ensure that the water level is maintained in the main cold water tank. If possible, you should use an automatic level controller. In addition to cleaning, you need to keep your system free from dust and debris. To make sure that your system is running at peak efficiency, you should also flush it once a year.


ENERGY STAR certification

If you’re considering purchasing a solar water heater, you should consider whether it’s ENERGY STAR certified. This certification is a great way to ensure your solar water heater is energy efficient. Solar water heaters with this certification are proven to cut carbon dioxide emissions by up to 50 percent. Moreover, these energy-efficient appliances have a long lifespan, which means they will last for over 20 years.


The EPA’s website offers detailed information about the energy efficiency of residential solar water heaters. You can identify the models that are ENERGY STAR certified by checking the ENERGY STAR label on their products. This information is also available for federal buyers who want to purchase energy efficient products. However, you should note that not all ENERGY STAR-certified solar water heaters qualify for the tax credit. The manufacturer’s certification statement is the best way to determine whether a solar water heater is eligible.
