When we consider having solar power installed in our homes, we often imagine a crisp array of dark blue panels fixed neatly to the roof, paying the electricity bill. But solar electricity is not the only way we can use solar energy in our homes.
While those panels can cost an arm and a leg without extensive government rebates, an equally important path to saving money is to install a solar hot water heater.
There are many benefits to this. First and foremost is a reduced energy bill. Whether you currently have a gas, oil or even electrical water heater producing hot water for your home, installing a solar unit will have a massive impact on your fuel bill and save you lots of money very quickly.
Less immediate benefits include having a more positive impact on the environment by harnessing a renewable energy source, and making your home more valuable. Solar water heaters work effectively in virtually any climate and latitude. It is very likely that you will be able to get a grant or rebate on the cost of the unit and installation, which should make it very affordable (In GA it's 35% of the total system cost as a Clean Energy Tax Credit capped at $2500 for solar thermal). There are plenty of reasons to go solar for hot water and none against it.
Once you’ve decided to go solar for your hot water, you’ll need to decide on the type of system you want. There are a few varieties. Active systems use a pump to drive water from the main tank into the heating tubes. Passive systems let water density do the work and do not require a pump, though they do need to have the tank placed above the panels.
If you live in a frost prone area you’ll need to go for a system that uses some type of anti-freeze in the collector tubes. These systems require a heat exchange unit as well so they may cost a little more.
Be prepared to shop around to get the best deal. Most installers are willing to come to your home to give you an accurate quote and will also let you know what system is best for you. By getting several such quotes you will be able to determine what you should be paying and what system you want. The more quotes you get the better a deal you will end up with.
