Estimated Delivery: 30 days. Average water temperatures will be 212 f degrees.
This is an excellent system. Grade a+ life is 20-25 years. We do not sell gray market or second market solar equipment
Works 24 / 7 day or night, even on cloudy, rainy, or snowy days.
Average water temperature 170-212 f
Save 70-85% on heating water cost. Some systems can also heat your home
Use the free energy of the sun to heat your water.
It is believed that 25-40% of domestic energy is used to heat water.
Approximately 80% radiation is turned into heat energy.
A study conducted by National Renewable Energy Laboratory (NREL) concluded that homes with solar water heaters sell 20% faster and for 17% more money.
Solar energy creates absolutely no pollution.
As the use of renewable energy continues to grow, the value of your home may increase as well, as more buyers seek out energy-efficient houses. A higher perceived value translates to a higher asking price when you are ready to sell your home
What is included?
Solar glass vacuum tube water heaters. (full 1800mm tubes including frame and manifold not the "mini" toy type)
This listing is a lot of two sets of 30 tube water heaters.
Sixty tubes total with two manifolds and frames with spaces for thirty tubes each.
These are the state-of-the-art in solar hot water heaters. Full 1800mm tubes. (almost 6 feet long)
These are the type without heat pipes, the tubes go straight into the manifold and the water goes into the glass directly.
Heat pipes are good for areas with extreme freezing temps
glass solar collectors 1800mmX58mm borosilicate glass
heat collector manifold
aluminum channel frame
All stainless steel
Header tube (where the hot water flows) stainless steel
outlet = stainless 1" NPS male thread (DN 25 OD 1.3.15")
Tip: To estimate the heat concentration of a vacuum tube system use 70W per tube
So, ten tubes would be 700 watts of heat in full sun.
Thirty tubes would be 2.1kW thermal energy.
Sixty, as in this listing, would be 4.2kW which is around what an electric
jacuzzi heating element would be rated at.
(But note, this one will be running all day long.)
In the summer that will be a bit much but how hard is that problem to solve?
