Making the Switch to Solar Pool Heating
Converting a gas or oil heated swimming pool to solar is not all that complicated. Almost every pool already has two key solar components - a pump and filter. Add solar collectors, piping, a flow control valve, a controller and you're ready to start saving.
Well, you're ready to start saving after your return on investment. Don't expect any tax credit help from Uncle Sam. Switching to a solar-heated swimming pool didn't make it into the Energy Policy Act of 2005. But many states do offer tax rebates or credits. To find out if your state participates, go to Database of State Incentive for Renewable Energy (www.dsireusa.org).
Pool size is the biggest factor in conversion cost. It determines how many solar collectors you'll need. From there it's basic math: The larger the pool, the more collectors you need. The more collectors, the higher the cost. Along with factoring in material and labor costs, there likely will be an outlay for removing or capping the old gas or oil heater.
"The contractor may need to remove the gas or oil heating appliances," says Patrick Robinson, an engineer for the Florida State Energy Center. "You may be charged for that."
All things considered, Robinson estimates that switching to solar typically costs about $4,000, give or take some. And while solar heating is less expensive when installed with the pool, even a later conversion will save money in the long run.
