Solar Water Heating

Where does your electric dolar go?Reliable, Pollution-Free Savings with Comfort

  • Save 85-90% of your water heating costs
  • Save 20-30% or more of your home's energy bill
  • Recoup your investment within 2-5 years
  • Help the environment as much as a hybrid car
  • Provides hot water during power outages
  • Qualifies for 30% Federal Tax Credit

While most people are captivated by the high tech nature of solar electric systems, a solar hot water system will harvest more energy at a substantially lower cost. In fact, compared to solar electric panels, solar hot water collectors are more than three times as efficient at producing energy from the sun. Investing in a solar hot water system is a smart solar solution, as this proven and reliable technology offers long-term performance with low maintenance. With federal and state incentives available, these systems offer a quick payback—in some cases, only two to five years. Make an investment in your home and the environment when you replace your old, inefficient hot water tank with a new solar water heating system. You will increase the value of your home as you decrease your energy bill.

 

System Function and Sizing

Solar Hot Water systems are designed to heat relatively small amounts of water (40-120 gallons in a home) quickly to high temperatures suitable for bathing, laundry and dishwashing. Most residential solar hot water systems in our climate include a solar storage tank, a small circulation pump and a flat-plate panel. Solar water storage tanks are well insulated and have electrical back up capability. The high temperature collectors are made up of a copper plate inside of an aluminum box with a safety glass coating. When there is sufficient solar energy available, the small pump circulates the water from the tank to the collector on the roof, providing you with hot water, courtesy of the sun.

 

Your Investment

Solar Hot Water heating is a great first step in controlling rising energy costs. Water heating is the second largest energy user in the home. In fact, only air conditioning and heating use more. The system costs average between $2500.00 and $3500.00 after government incentives and will often pay for itself in two to five years depending on how many people are using hot water in the home. A professionally designed solar hot water system could provide all, or at least a significant amount, of your household hot water needs for the entire year in sunny South Florida. To get the most for your money, you will want a properly sized system that offers the best performance in our climate. Installing a solar hot water system directly reduces your consumption of fossil fuels and eliminates over one ton of Carbon Dioxide emissions each year. Properly maintained systems can offer 20 years of worry-free operation and free hot water courtesy of the sun.

 

 

 

How does a solar water heater work?

 

How does a solar water heater workSolar hot water systems absorb the sun's heat using a flat-plate collector. When there is sufficient solar energy available, a small pump circulates the water from the tank to the collector on the roof, into a large storage tank providing you with hot water, courtesy of the sun. In general, the solar thermal system will easily heat water to 140ºF or higher matching the range of its traditional hot water tank counterpart. The solar storage tanks are well insulated and have electrical back up capability.

 

Does my existing tank need to be replaced?

Yes. To provide adequate hot water storage, the tank is upgraded to a larger size. The solar storage tanks are better insulated and will operate more efficiently than standard tanks.

 

Will I have hot water if it is cloudy?

Yes. A solar hot water system stores the hot water in a specially designed, highly insulated storage tank. It can hold a one to two day supply of hot water. The tanks are also equipped with electrical back up in the case of an extended period of inclement weather.

 

Does a tankless water heater make better sense than a solar hot water heater?

Not necessary, the water you use is still being heated by electricity and the amount of energy used to heat a gallon of water is the same. The tankless style heater only eliminates the energy cost to maintain the temperature, so it only 10 to 15% less expensive than your current electric water heater. Tankless units can struggle to provide all of a home hot water needs simultaneously, which may mean you have to wait to shower if the dishwasher is running. Solar hot water system can provide a 90% saving from your current water heater and will provide plenty of hot water.
