Heating and warm water provision
Systems: -geothermal system (heat pump)-solar thermal collectors-electric heating system
Heat pump systemsTypes
From:• Ground
• Water
• Air
Into: Air
Water
Types•Ground
•Collector:1,8m (C)•Soil probe:100m (B)
•Water•Tubesystem: (A)
•Natural waters•Drilled fountains
•Air•ventilators
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
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
= 50 liter 45°C water
= One person warm water
consumption
Electric Heating
