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

Heat pump systems Types 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 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 collector Important 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

Types Vacuum 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 (m 2 ) – Type of heating system – Quality of Insulation + Material Coating Datas: (example) Wagner & Co. Solartechnik: – Plain collectors Produce: (in Germany) 546 kWh/m 2 /year = 50 liter 45°C water = One person warm water consumption
