Ground heat exchanger GHE
Smart Home , intelligent Building eHouse – Use GHE for recovery of free energy of the earth .
The ground heat exchanger is well-known component of the ventilation system and recuperation . It involves placing deep underground (minimum 1.5m) in the form of heat exchanger tubes of large cross-section (eg 200mm ) or deposits of gravel .

Solar collectors Water and Air “Solar Farms”
Smart Home , intelligent Building eHouse – the use of solar collectors to obtain free energy heating .
There are many types of solar collectors and many forms of divisions and categories
- parabolic – focusing
- rotary – tracking the sun
The technology of manufacture and the type of the collector have an impact on the efficiency and performance , insulating medium , deviation of the heat transfer element to the entire surface of the collector .
We’ll take care division at medium receiving heat from the collector :

Heating foundations and hobs – escape of heat into the ground
Smart Home , intelligent Building eHouse – Heating foundation of free energy in order to reduce the escape of heat energy .
Through the foundation and the base slab is running a significant amount of heat energy , because of the high heat-transfer coefficients of the concrete . In addition, it is not possible warming of foundations and underside of the support plates which is very effective thermal bridge . Continue reading Economic House – heating foundations
Well water for cooling in summer and heating in the winter instead of GHE (Ground Heat Exchanger)
Smart Home , intelligent Building eHouse – can use well water instead of GHE for energy .
Ground heat exchangers have a number of drawbacks discussed earlier ground heat exchanger advantages and disadvantages. On some particularly agricultural plots and farms can provide an alternative which is much better and more effective from GHE.
Old farms usually have water wells will be even cheaper solution than.

Storage of renewable energy , solar , heat
Most of renewable energy sources to have an average energy balance (averaged over one year cycle) a very low or even zero .
All renewable energy sources like wind , sun , heat , etc. . are temporary and require storage and accumulation ,much later than is the ” overproduction ” .
