I'm considering to heat my future home on solar power, but I can not
find much information on the Internet on heating. Most of the
information is about heating tapwater. We do not use much hot tapwater,
so we don't expect serious savings there.
I wonder how many square meters solar collectors are needed and
how many liters storage for the hot water.
This question is a great deal like asking "How long is a piece of
string?"
With no information about where the house is, what size it is, what the
incoming sun resouce is, the local climate, the specific values of
insulation, it's quite impossible to say how many square meters of solar
collector you need, or how much hot water storage you need.
In a mild climate - less. In a harsh climate - more. Few cloudy days in
a row - less. Many cloudy days in a row - more. Well insulated - less.
Poorly insulated - more.
do you know where I can get some information?
alt.solar.thermal - read the archives for a lot of solar house heating
background information, then post some specifics about your house design
and house site. I'm guessing, since you asked about square meters of
collector, that we'll need to try to recall what the European R-values
for insulation actually refer to, since most regulars on that group are
using US R-values based on imperial units and will need to convert to
consider your design, and I'm not recalling what the underlying units
for the metric version of the same number are.
