?? about types of solar water heaters
OK, I'm getting down to the final choices for building our ICF house. We decidede that photovoltaic systems are just not cost effective enough right now to invest in with our tight budget so we're putting that money into the tightest, most solid structure possible.
But I do think that here in Florida solar water heaters are definitely cost effective. I've seen three different types of systems: building integrates, passive systems that directly heat the water use standard tank water heaters for backup and passive systems with integrated tanks that use glycol to heat the water.
The dealer does not recommend the intergrated building system type - with that system, the piping for the collection loops is installed under a metal roof. If there is any leakage, not only does it come right through the roof sheathing, you've got to tear out your roof to repair it.
I'm sort of drawn to the type with the integrated tank - that seems as though it would limit the plumbing connections and therefore limit the possibilities of leakage. Plus since it is one system, there could be no finger-pointing in the case of problems.
Also, I was concerned about where the water heater tank would be located in the houseand this takes it completely OUTSIDE!
Here are the two systems I am comparing:
Any advice on either of the two types of solar water heater? Any advice on other brands I should consider. A note on this - my BIL is a dealer for Eco-$mart, so I will get a discount of these systems. ;-) But I want to buy a good system, not just get whatever I can get for cheap!
