Solar Hot Water Heaters
Most people don’t realize that the most efficient solar system for a residence is a solar domestic hot water heater (SDHW). Even if you wanted to invest in Photovoltaic, you should consider a solar hot water heater for a better return.
Depending where you are in Florida, you have a few options as far as hot water system components. For the majority of central Florida, the best and most reliable option is for a direct, flat plate system. It’s the most efficient system on the market and is used in central and southern Florida, as it is not a good system in areas that may freeze.
Solar water heaters are more efficient the gas or electric heaters.
Solar water heating systems usually cost more to purchase and install than conventional water heating systems. However, a solar water heater can usually save you money in the long run.
How much money you save depends on the following:
- The amount of hot water you use
- Your system's performance
- Your geographic location and solar resource
- Available financing and incentives
- The cost of conventional fuels (natural gas, oil, and electricity)
- The cost of the fuel you use for your backup water heating system, if you have one.
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.
After installation, properly maintaining your system will keep it running smoothly. Passive systems don't require much maintenance. For active systems, discuss the maintenance requirements with your system provider, and consult the system's owner's manual. Plumbing and other conventional
water heating components require the same maintenance as conventional systems.
Regular maintenance on simple systems can be as infrequent as every 3–5 years, preferably by a solar contractor. Systems with electrical components usually require a replacement part or two after 10 years
