Buying a 'DIY' Solar Heater (Water/Pool) on Internet?
We're looking into cutting electricity costs for our 1 story 1700 SF house in Southern California. I did a web search and there are a MULTITUDE of sites claiming you can build your own system for under $200 and save from 30% to 80% off your electric bill. You just need to purchase their "super easy detailed step-by-step" plans for around $40.00.
Is a plan from one of these sites a good purchase?
If not, is this information available for free somewhere?
Is it possible to get all of the components from your local hardware store for under $200?
We were originally thinking of just a solar pool heater and/or hot water heater but the plans say you can furnish your entire household with solar...still under $200.00.
Your advice is greatly appreciated.
