how to heat your home with solar energy

Heating their home with solar energy is a difficult task, because when you need it is just the warm up period when the sun is weak.

As we always say, to get the best result requires action on several fronts: using multiple technologies and with a proper design of the building.

With regard to the heating system can also obtain a coverage of 60% of heating, (in addition to almost 100% of requirements of domestic hot water for showers and sinks).
To obtain this result must first install a number of solar panels.
Sorry if I disappoint someone, but from experience I believe in general in Italy do not need (!) Particular types of solar panels. Just that there are many, that have large absorbing surface.
If instalate closed-loop systems (eg vacuum panels, usually recommended to those seeking to integrate the warming because yields have also improved during the winter months) attention to the surplus heat in summer and how it is disposed of!
The concept is this: if I produce a lot of heat in the winter when I need it and there is little sun, where do you dispose of it when I need it and the sun is? -> Problems!
Usually the answer-not-say is that I open the cold water tap and dispose of sewage in the warm to hold the storage temperature. This is normal, but understand it’s crazy energy and the environment!
And ‘so that if you install solar panels Sometimes you feel advised to build a swimming pool: why your heating engineer (or a plumber, or someone else) has not yet solved all problems!
Another thing I’ve heard and seen in fair-to-cover with solar panels in the summer of towels: I guess the operation very easy to do!
PS: with the safety rules that-rightly-rage, what must I do to garanire the safety of those rooms on the roof staring at the towel?

Who wants to make warming winter sun with the best when used with solar panels to drain.
This is a technology sempòice and that is spreading increasingly to the undeniable advantages.
When the temperature in the panels rises too the circulation pump stops working (= saving) and the panels are emptied.
I have no problems with the water boils at 100 ° C and that (to prevent this) must be added with glycol, but acidifies and must be replaced every two years (= maintenance and environmental impact), otherwise corrode the pipes and the pump!

Rather, we need a suitable collection surface: at least 9 square meters to cover about 150 square meters of a house is well insulated. Of course, if the plates are emptied they fall contraindications to install more.
It ‘s also essential to accumulate as much hot water prodota possible, to compensate for the discontinuity of production of the sun.
Consider if heated by the sun are not the worst of the cold and sunny, but temperate ones but covered! Even with -10 ° C outside and the sun de December 21, panels can operate at full capacity and produrmi water at 70 ° C!
It is therefore necessary to think to install a tank of at least 800 liters (but the dimensioning also depends greatly on the internal functioning of the tank and the type of internal stratification of the hot water)

In the house must have a heating system operating at low temperature, that is, with radiant panels under the floor or wall below. This is because the winter solar panels produce water at moderate temperatures, that is not normal to adaterebbero radiators, which instead operate with very hot water on surfaces restricted.

If I have a normal type of heating radiators (the so-called heat registers or radiators), I can keep it only if I can make them work at low temperature (40 ° C).
I can do this by increasing the surface with the addition of some form, but especially if I insulated (isolated) very well the house ….
I always recommend-without changing the system-to replace them with the radiant tube for putting under a fresh coat of plaster: the gains are very evident both in savings and comfort.

The approximate cost of a solar heating of about 150 square meters of housing is about $ 8,000, whereas 9 square meters of panels, type of high quality vacuum tubes and a tank of 2,000 liters. This amount may be encouraged by local funding (regions and municipalities) and national (income tax deductions of 36% or 55%).
