Home Automation , Home Automation eHouse – Heating foundation from free energy to reduce heating energy escape .

Through the foundation and base plates running a large amount of heat energy , because of the high heat-transfer coefficients of concrete.

In addition, it is not possible warming of the foundations and supporting the bottom plate which is a very efficient thermal bridge .

We give general recommendations , which in some circumstances may be cost-effective in other irrational.

Of course, we write about solution for many years (over 20) use of home, and refund itself after a few years.

The first way to reduce leakage to ground , be taken into account is the foundation of the building above the groundwater level at any time of the year (preferably 0 . 5 – 1m) .

Water and moisture substantially increases (up to 20 times with respect to air) heat permeability materials .

Additionally oozes upward capillary walls and floors getting wet home , also causing extensive damage and weakening of the material , Fungus , mold .

Dry house will be much more economical to heat in winter and cool in summer .

Another way is the foundation of your home for loose soils (sands), which have slightly lower thermal transmittance.

In the case of clay soil even the exchange of land for tens of centimeters thick sand , can give positive effects of energy gains.

Said, of course, you need to thicken the ground to get the required capacity for continuous footings or foundation slab.

Houses on sandy soils are much drier due to less capillary water and moisture .

In addition, sandy soils are more stable in relation to the clay in particular for casting or rising ground water .

In these cases, the clay becomes malleable and soft, which results in , the building “works” , break the wall , footings , connect to chimneys and walls switching places, where there are different emphasis on land .

Another way to reduce heat loss through the foundation or floor slab foundation is the use of heating (alternative). These solutions apply Nordic countries (very far north) where they are much more adverse weather conditions than in Poland or central Europe.

Heating foundation can be done in 2 ways:

• air heating
• Water Heating

Heating Air

It involves placing a tube in the slab foundation with a diameter of 10cm , which eventually flows through the warm air from the green energy.

Unsealing the tube does not matter as these air flows, so that it can act effectively to ” end of life ” home .

However, air has a much lower coefficient of heat transfer from the fluid so the efficiency of such heat for cooling the ground is too high .

Pipes have a much larger diameter than the heating water which requires a much thicker screed .

Water Heating

It involves placing the foundation board , benches or the ground floor directly under the floor of the water pipes for underfloor heating . This gives a much more effective heat transfer comparing to the air heating .

The tube is placed in a casing tube which is to reduce the pressure directly on the tube .

Here are the negatives of factors such as mechanical failure or when installing the pipe during operation which would lead to the use of heating (it is impossible to repair) .

Damage to or loss of containment pipe will wet slab which is also a very negative consequences .

Water pipes have a much smaller diameter than the air and can be applied not only to the base plates as well as , ceiling , stair boards and other concrete materials at home .

Heating low-foundation work – Temperature , at temperatures well below the underfloor heating and heated plate to room temperature leads to an overall reduction of heat loss to the ground by the foundation (the difference in temperature of 0 degrees) .

Concrete and soil is also relatively high thermal inertia , and the slab heated to higher temperatures greatly reduce the expenditure on heating .

Heating to higher temperatures makes sense only as a storage of excess heat , because this method of heating is mainly to reduce energy leakage to the earth , rather than heating the whole house .

Heating foundations is economic of free energy such as Solar system (water or air) .

You should also take this into account in the planning of the solar heating.

For example, if you ultimately intend to use only water collectors, the board must use water pipes, and vice-versa .

When water collectors , which have a very low efficiency in winter , water circuit can switch on the foundation at the collectors do not give a sufficient temperature for heating the water but it is sufficient to heat the foundation and its energy storage.

This way you can warm up the floor slab.

In February when the outside temperature is very low (less than – 10C) , but the sun is shining and solar system works .

In addition, when traveling in the summer, we have the opportunity to switch the heat from the solar system to the foundation , which protects them from damage due to lack of heat reception.

When planning such heating should not be limited to the heating of foundation .

Similarly, you can heat the basement floor , garage , ceilings , stair board , poured concrete walls , that will allow for the storage of free solar (thermal) energy and reduced spending energy by heating up house.
