PV Gap

Rafael Said:

Which is more effecient and more successful? A Tank-less Waterheater of a solar-powered waterheater?

We Answered:

My folks have a tankless water heater, and they love it. It is electric, and doesn't use any power until the hot water faucet is turned on. Then, it only runs to heat water going through the pipe. As soon as you turn off the faucet, you turn off the heater. It's instant heat, and unlimited heat. Here is the website that they bought from. Others have used it and love it as well. Very efficient to use, and not much money to set up. Solar water heaters would work great, but they are expensive to set up. It takes a long time to make your money back with those.

Does anybody out there have thermodynamic solar collectors?

this is not exactly what your talking about but I made a solar water heater to pre heat my water before it goes into my water heater in my house and it works great( I drooped my elec bill just by the preheat and a timer on house water heater to turn off at night ) but I live in fl we get two seasons hot and hotter not sure how it would be up north( also put my stove and dryer on gas to save more)
