If you’re currently researching ways to utilize the technology of solar power inside your home, we commend you and appreciate your efforts to save some money while also saving the planet. Today, we want to discuss an incredible way to leverage solar technology to take advantage of the sun; to produce hot water for your home. As well as discussing how it works, we’ll also explain the different types of systems and the potential cost of such a system. For more detailed information about the cost of converting to a solar hot water tank, you can visit the industry experts at http://www.phoenixgreenteam.com/solar-water-heater-cost/
How Does a Solar Hot Water Heater Work?
Much like solar PV panels, solar hot water heaters work from thermal ‘collectors’. With traditional panels, they aim to convert the energy from the sun into electricity. With thermal collectors, their aim is to still collect the same energy but use the heat to provide hot water for the home. We’ve broken the process down below;
• Firstly, the collector panels on the roof will contain small tubes of water which are summarily warmed by the sun.
• Once this water is heated, potentially up to 90 degrees Celsius, it passes into your home and normally into a cylinder or storage tank.
• Using a system of pipes, the hot water is then ready to use around the home.
The first thing we should state is that you will still need your traditional immersion heater or boiler because the hot water provided by your solar hot water heater might not be enough to cover all your needs. For many experts, they believe solar energy can provide up to 70% of a family’s hot water needs and this allows for significant savings. Suddenly, your home will only be using traditional sources for 30% of water and the rest is free.
Types of Solar Thermal Collectors
Evacuated Tube Collectors – With this first option, several glass tubes will be placed alongside one another on the roof. Using a partial vacuum, these tubes have an absorber and allow the water to be warmed by the sun. Traditionally, this option is more expensive but many prefer it for its aesthetic appeal (some also argue for its efficiency over the next option!).
Flat Plate Collectors – With a similar appearance to regular solar panels, an absorber plate containing metal tubing sits on the roof and the casing is perfect for retaining heat. Fluid continually runs through the tubing and is then heated by solar power.
Cost of Solar Hot Water Heaters
Now, we reach perhaps the most important question (and possibly the reason you clicked onto this fantastic guide in the first place!). How much of an investment will you need to make to get this system installed in your home?
In the US, you’ll pay up to $5,000 for the whole system…but we have good news. Many states offer solar incentives which will allow you to receive a discount (or a portion of the cost paid on your behalf!). In addition to this, you also need to consider the difference in energy and water bills for your home. Rather than paying every single time you want hot water, up to 70% of your hot water needs can be covered for absolutely no cost. If you plan to stay in your current home for many years to come, the system will eventually pay for itself. Even if you don’t plan to stay forever, the solar hot water heater will add value to your home so you could probably recuperate the cost of an installment when selling.
All things considered, solar hot water heaters are fantastic pieces of equipment that allow you to save money and help the environment. Why not look into the incentives near you to see if you can get help today?
