CoEnCo Solar Boilers
CoEnCo solar boilers use heat pipes in vacuum tubes. These are many times more efficient than normal flat plate collectors. Also flat plate collectors are available at very interesting prices.
Available are: Split Systems Compact systems Flat plate collectors

Heat pipe The heat is passed on to the heat pipe by means of a small copper head. The most important function of the heat pipe is to pass on the heat to the medium that must be warmed up. The heat pipe is filled up with a liquid that evaporates at a relative low temperature. The liquid evaporates by the sun in the warmed up vacuum tube. The evaporated gas rises to the relative cold upper side of the heat pipe. There it condenses again by release to the medium that must be warmed up. The energy of the condensation is passed on to the manifold around the streaming liquid. On its turn the condensed liquid streams down and the cycle repeats again. The cycle stops when the sun stops heating the vacuum tube. This prevents the reflux of energy.

Wind energy with CoEnCo A general survey
 Some easy calculations.
What may be your profit?
Normally you can expect minimal 1500 usable wind hours (2000 following some sources) depending of your site. This is certainly true for the CoEnCo wind turbines because our turbines reach a nominal capacity at 8 to 10m/s (28 -36 Km/hour) and start already up with an average wind speed of 3 to 4m/s (10 to 14km/hour)
The calculation is made in no time. You buy a turbine of for example 2kW Nominal. This turbine will generate, on a annual base, (minimal) a return of 1.500 x 2kW= 3.000 kWh. This is for a private house already a beautiful return on the general electricity consumption. At the same time you get a ”green certificate” which returns 110€ per 1000 kWh or a supplementary return of 330€ on annual base.
The investment will be repaid within 3 to 5 years. The average total investment for a complete system of direct supply to the grid costs about 2.4 at 3.3€ per watt. This is the best investment. For a system on battery independant of the grid costs about 1.6 at 3.1 per watt

The CoEnCo lighting post
CoEnCo can even offer you an original lighting post for your entry or your access road existing of a wind turbine of 400 Watt in combination with solar panels of 2 x 50 Watt. The lamp itself is a 35 Watt lamp. Depending of the height of the post it will generate between 12 and 35 Lux (at a height of 7 m >30 Lux)
In the soccle of the post is a hidden battery which gives you an autonomy of 30 hours light. (this by lack of wind and sun what is equal to +- 4-5 nights without recharge). The controller and the invertor are also fitted in the soccle of the post. This is a very comfortable system and needs no further connections.
