Alongside traditional gas or electric water heaters, solar units are always booming in their demand. Yes, you should consider them when living in sunny areas, however, they may fit climates with cloudy weather as well. Today, you can start by finding a contractor, because the specialists have the ability to guide you through the best systems available in the market. Otherwise, we offer you to take a look at the below-mentioned solar water heaters that have high rankings and can fit various homeowners.
Let’s remind you how solar water heaters work. All such systems come with storage tanks alongside solar collectors. Then, depending on the functionality, they are divided into 2 types – active, and passive ones. For instance, when choosing active water heaters, they may be with direct circulations. In simple terms, their pumps circulate water via the collectors into the house. They are a go-choice for climates with rare freezes. Then, active units may come with indirect circulation. In this case, their pumps circulate non-freezing fluid via the collectors and a heat exchanger. So, it first heats the water and then transfers it into the household. They are a go-choice for climates with occasional freezes.
What about passive solar water heaters? First off, they are less expensive, but there is a drawback as well – they are not highly efficient. They are also divided into two types. The first one is integral collector-storage units which consist of storage tanks with designated materials that help the sun heat the water. After that, the water from the tank passes into the plumbing system. Finally, there is a thermosyphon system that has water heated in a collector mounted on the roof and transferred to the plumbing system when you open the hot water faucet.
Now, let’s offer you some choices in terms of the best solar water heaters.
