Benefits of Solar Water Heating
Solar Water Heaters Work In Every Climate
Today's SWH technologies can be operated efficiently and affordably in any climate. Systems are specifically designed for various climatic and geographical areas of the country.
Reduce Energy Costs
By installing a SWH system, a typical household can meet 50 to 80 percent of their hot water needs. In southern climates, a SWH unit can meet nearly 100 percent of a household's hot water needs.
Proven Efficient Technology
Currently there are more than 300,000 SWH units installed across the United States (excluding swimming pool applications) and because these systems have been proven efficient and reliable, the number of installations continues to grow by the thousands every year.
Improved Environment
Reduced demand for fossil fuels will improve the environment by reducing air and water pollution as well as the heat-trapping gases that cause global warming. And though they cost a little bit more up front to install, a SWH system will save consumers money in the long run as the fuel source (the sun's energy) will always be free.
Types of Solar Water Heaters
There are two basic types of Solar Water Heaters:
Passive
Warm Climate
- Easy to install and maintain; has no moving parts
- Storage tank must be installed above or close to collector
- Uses no electricity; will function during blackouts
- Price range: $1,700.00 - $2,600.00
Active
Moderate Climate
- Flat plate type collector
- Pumps, valves & controllers assist in the prevention of freezing
- Tanks do not need to be installed above or close to collectors
- Uses electricity; will not function during blackouts
- Price range: $2,200.00 - $5,200.00
Cold Climate
- Evacuated tube type collectors
- Heavy-duty residential and commercial
- Additional applications: Radiant floor heating, Space Heating
- Price range: $6,000.00 - $17,000.00
