Water heaters that use solar energy pull from the sun’s energy to heat the water. The cost of a solar heater is quite expensive although, you can save thousands of dollars in electric costs as you no longer need to use your electric to heat your water. One of the downfalls of these heaters is that they are no longer supported by current tax credits. They have become more reliable, more efficient than traditional water heaters, and are less expensive.
Living in a climate that is mild and has the capability of heating water for the entire home one can have one of these heaters installed for between $2000 and $5000. This makes solar heaters extremely competitive compared to traditional gas and electric heaters. Solar water heating systems typically have an average annual operating cost of $50 to $75. An electric or gas water heater can cost over $500 a year to operate.
Solar water heaters work by acting as a pre-heater for a standard storage water heater or on-demand water heaters. These heaters work extremely well with on-demand heaters that have temperature adjustability. Since solar systems preheat the water in the tank, that extra boost required for on-demand heaters to work is much lower. Homes that use these heaters tend to save a lot of money every month and get a higher flow rate.
If you have been thinking about installing a solar heater and a south-sloping roof, you are at a higher advantage than most people. This makes installing the heater easier and it will run more efficiently. Most families who live in colder climates use solar power as a three season system and will then use a traditional gas or electric water heater during the colder winter months.
Before having the heating system installed, do your research to look for highly qualified installation companies and a dealer that both design and size your backup system. Make sure you ask to see certifications to install and maintain solar heaters and ask for testimonials and reviews from previous customers.
One thing to keep in mind is that with any water heater, their life span is only about 10 to 15 years. This is also true for solar water heaters. What you will save a year in energy costs could potentially pay for a new solar heater and you will feel more at ease knowing that you using an eco-friendly method to heating your water.
