Important datas

Sizing & planning• planner's responsibility:

– Building area– Orientation– Structure

Costs• Depend on:

– System– +/- tank– Internal/external– Including the necessary

devices and structures– Type of heating

• Number of the users

Perfomance

Air heating system• Pros:

– We need only 2-3 kW power to move 10 kW heat (about the heating claim of a family house )

– Cheap• Cons:

– We need the electrical system to make it effective

– Low efficiency– May be need a supplementary electric

system on the cold winter days – Proposed to heating systems with a very

low temperature

Geothermal probes• (depend on the construction of the soil) we can produce 20-100 W./metre.

• The temperature of the soil after 15 metres constant, these layers do not get cold in winter.

• The depth of the probes, and it’s number is necessary to elect according to the heat claim

• Pros:– Closed system– Higher efficiency than air/water heat pump– We need less area for drill– We don’t need permission until 20 metres

• Cons:– Expensive to set up– 20 metre isn’t enough– We need an electric system to make it

effective

Soil heat collectorImportant datas

• Pros:– If we have enough area it’s

cheaper than geothermal probes– Closed system– Don’t need permission

• Cons:– Medium efficiency– Depend from the shining,

outdoor temperature– It limits the garden(area)

usability– We need an electric system to make it

effective

Solar thermal collectors• Collect heat from solar radiation

– Heating– Warm water

Page 8: Heating and warm water provision Systems: -geothermal system (heat pump) -solar thermal collectors -electric heating system

TypesVacuum tube• Tube+tube = vacuum

Plain• Absorber surface

Thermosyphonic system•Solar thermal collectors + Hot water storage tank

Perfomance

• Depends on:– light transmission

• HTF=91%=82%• AR=96%=86%

– Area of rooms (m2)– Type of heating system– Quality of Insulation +

• Material• Coating

• Datas: (example)

• Wagner & Co. Solartechnik:– Plain collectors

• Produce: (in Germany) 546 kWh/m2/year
