arrogance and ignorance is an unfortunate combination.
the sustainable village also sells spanish sky mats for about $50...
lowest cost solar thermal panels
the least expensive way to heat enough water for regular showers. unglazed
so only practical in areas that don't freeze or for summer only use. also
great for swimming pool heating. the absorber area should be chosen 50%
larger if there is no cover. the regionally different number of sunshine
hours can be allowed for by adding or deducting up to 20% absorber area.
the flow rate should be 150 to 250 l/m^2 absorber area per hour. the
required type of pump is easy to determine. the delivery rate is calculated
from the absorber area x 200 lts. the delivery head is the difference in
height between the water level and the absorber panel plus approx. 5m.
each panel measures length 1320 mm - width 820 mm - 1.08 m^2 with 4 couplings
dia. 25mm (type a) or with integrated collecting pipe dia. 40 mm and two
couplings dia. 25 mm (type b) recommended absorber area in % of pool surface
for open-air pools with cover or indoor swimming pools (early may through
end of september). temp increase 4-7 c compared to unheated swimming pools.
type a is for the first and last in a connected series and has a 40mm header
for the water to flow in. type b is for the panels in between and connects
with 25mm hose connectors to make as large a collector as needed. for
example, if you wanted to join 10 together in one line, you would buy 2
type a for the flow in and out and 8 type b to couple up between the two
end panels. fob spain
