What’s a Solar Water Heater?

At their most basic, solar heating systems act as greenhouses for water. The technology isn’t new; the first system was patented in 1891. Systems have improved since then, and today, they use a set of solar panels — known as a solar collector — that trap heat. This heats the water, which is then stored.

When deciding on a solar hot water system, you can choose between an active system and a passive system. The main difference is that active systems have a circulating pump and controls. Passive systems tend to be less efficient, but they are less expensive and often last longer. An installer can help you determine which type works best for your home, water needs and location.

Is a Solar Water Heater Worth It?

The answer to this question is always going to depend on your individual circumstances, but most people find a solar water heating system is a good investment. If you’re trying to build a more eco-friendly lifestyle, solar water is a great addition to your home as it decreases your carbon footprint.

Even those not interested in going green for the environment find that a solar system helps give them more green financially by putting more money in their pocket. Although upfront costs can be high, these systems pay for themselves over time by reducing your energy bills.

However, solar hot water systems aren’t without their disadvantages. Your potential savings can differ depending on where you’re located, and some homeowners have to pay additional costs to prepare their homes for the systems. It’s important to understand both the pros and cons of installing solar hot water before deciding if it’s right for you.

What Are the Benefits of Solar Hot Water?

Cost Savings

The India Department of Energy estimates that 30% of a household’s energy use goes toward heating water. In most homes, it accounts for the second-largest energy expenditure behind space heating. But once you have solar hot water installed, it doesn’t cost anything to heat the water because using the sun is free. The exact amount you can expect to save depends on a number of factors, such as how much hot water you use and where you live. However, the says that the average Indian household saves 60% to 80% on their water heating bills after installing a solar hot water system. You’ll also be protected if there are fuel shortages or rising energy costs in the future.

Increased Home Value

Homes with green features are becoming increasingly popular, so solar hot water can help your resale value. It’s likely solar hot water will add value to your home when you’re ready to sell as buyers continue to look for energy-saving and environmentally friendly housing options.

Environmentally Friendly

Solar hot water systems have a electric backup system for overcast days, but most of your hot water is heated using 100% renewable energy. This means you’re lowering your household’s carbon footprint and keeping greenhouse gases out of the atmosphere.
