Solar Water, Flat Plate Collectors.
Flat plate solar collectors ( aka "Flat Plate Water Heaters") are ideal for domestic solar water heating and solar pool heating applications.
The flat plate solar collector is often believed to be more effective at lower temperature differences than vacuum tubes.
Sun Power Is Free Power.
On average, if you install a solar water heater, your water heating bills should drop 50%–80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes.
Often solar systems are calculated or engineered for the time period they will pay for themselves in savings.
A solar water heater can usually save you money in the long run; however, many buyers are scared away by the initial costs, which are often more to purchase and install than conventional water heating systems. It's not the initial cost, it's the savings on opperation.
How much money you save depends on the following:
- The amount of hot water you use, not total water used.
- Your system's current performance and efficiency.
- Your geographic location and sunlight availability.
- Local/federal financing and incentives
- The cost of conventional fuels (natural gas, propane, oil, and electricity)
- The cost of the fuel you use for your backup water heating system if you have one.
If you're building a new home or refinancing, the economics are even more attractive. Including the price of a solar water heater in a new 30-year mortgage usually amounts to between $13 and $20 per month. The federal income tax deduction for mortgage interest attributable to the solar system reduces that by about $3–$5 per month. So if your fuel savings are more than $15 per month, the solar investment is profitable immediately. On a monthly basis, you're saving more than you're paying.
