Speaking about water heaters, do you know anything about solar heaters. They were popular before Reagan did away with the tax credits you could get for buying one. Anybody have any recent experience ?
I can't see them being cost effective at this time. Unless you convert all your lights and appliances to run on DC voltage you will have to use an inverter and many, many batteries to get any useful power out of it. May can use it to heat hot water, but I just don't see any savings when you factor in the cost to buy and install the system.
Ex co-worker of mine had installed a heat pump system that uses the earth to help cool in the summer and heat in the winter. The subsurface of the earth doesn't have a lot of temperature variability, so you just basically circulate water through it to provide cool water in the summer and warm water in the winter to the HVAC system. This greatly enhanced the efficiency of the unit. This alternative is much more affordable and once installed has very little maintenance, if any.
Hoober, thanks, but I believe you mistook what I was asking; not solar electric panels, but direct solar water heating.
Back in the 1st energy crisis, Carter instituted tax credits to people who would put them in, and since they cost at the time around $2000, after the credits, the installed cost was not too bad.
I was living in the Memphis area at the time, and a lot of people were putting them in, and as a result, a lot of small outfits were selling and installing them.
Reagan, in typical pro energy company fashion , did away with those tax credits and that entire industry dried up. Clinton tried to get them back, but the congress would have none of it. Lewinski was much more important to our economy and energy independence.
I heard somewhere that some of those credits had returned, but don't know how to find out, or who sells those heaters. If I could get one with a deal like in the 70's I would , and I was wondering if anybody knew .
